You can do it in one line without nltk (python 3.x).
import string
string_text= string_text.translate(str.maketrans('','',string.punctuation))
While it is nowhere nearly as clean, but you could implement something like C# delegates using a Java Proxy.
If you need more than this, for example securing a connection string (for connection to a database), check this article, as it provides the best "option" for this.
Oli's answer is also good, as it shows how you can create a hash for a string.
I tried something similar and was able to reproduce the problem (IndexOutOfBoundsException). Below are my findings:
1) The implementation of the Collections.copy(destList, sourceList) first checks the size of the destination list by calling the size() method. Since the call to the size() method will always return the number of elements in the list (0 in this case), the constructor ArrayList(capacity) ensures only the initial capacity of the backing array and this does not have any relation to the size of the list. Hence we always get IndexOutOfBoundsException.
2) A relatively simple way is to use the constructor that takes a collection as its argument:
List<SomeBean> wsListCopy=new ArrayList<SomeBean>(wsList);

The event
attribute of <f:ajax>
can hold at least all supported DOM events of the HTML element which is been generated by the JSF component in question. An easy way to find them all out is to check all on*
attribues of the JSF input component of interest in the JSF tag library documentation and then remove the "on" prefix. For example, the <h:inputText>
component which renders <input type="text">
lists the following on*
attributes (of which I've already removed the "on" prefix so that it ultimately becomes the DOM event type name):
blur
change
click
dblclick
focus
keydown
keypress
keyup
mousedown
mousemove
mouseout
mouseover
mouseup
select
Additionally, JSF has two more special event names for EditableValueHolder
and ActionSource
components, the real HTML DOM event being rendered depends on the component type:
valueChange
(will render as change
on text/select inputs and as click
on radio/checkbox inputs)action
(will render as click
on command links/buttons)The above two are the default events for the components in question.
Some JSF component libraries have additional customized event names which are generally more specialized kinds of valueChange
or action
events, such as PrimeFaces <p:ajax>
which supports among others tabChange
, itemSelect
, itemUnselect
, dateSelect
, page
, sort
, filter
, close
, etc depending on the parent <p:xxx>
component. You can find them all in the "Ajax Behavior Events" subsection of each component's chapter in PrimeFaces Users Guide.
Bash's set

In C++11, the using
keyword when used for type alias
is identical to typedef
.
7.1.3.2
A typedef-name can also be introduced by an alias-declaration. The identifier following the using keyword becomes a typedef-name and the optional attribute-specifier-seq following the identifier appertains to that typedef-name. It has the same semantics as if it were introduced by the typedef specifier. In particular, it does not define a new type and it shall not appear in the type-id.
Bjarne Stroustrup provides a practical example:
typedef void (*PFD)(double); // C style typedef to make `PFD` a pointer to a function returning void and accepting double
using PF = void (*)(double); // `using`-based equivalent of the typedef above
using P = [](double)->void; // using plus suffix return type, syntax error
using P = auto(double)->void // Fixed thanks to DyP
Pre-C++11, the using
keyword can bring member functions into scope. In C++11, you can now do this for constructors (another Bjarne Stroustrup example):
class Derived : public Base {
public:
using Base::f; // lift Base's f into Derived's scope -- works in C++98
void f(char); // provide a new f
void f(int); // prefer this f to Base::f(int)
using Base::Base; // lift Base constructors Derived's scope -- C++11 only
Derived(char); // provide a new constructor
Derived(int); // prefer this constructor to Base::Base(int)
// ...
};
Ben Voight provides a pretty good reason behind the rationale of not introducing a new keyword or new syntax. The standard wants to avoid breaking old code as much as possible. This is why in proposal documents you will see sections like Impact on the Standard
, Design decisions
, and how they might affect older code. There are situations when a proposal seems like a really good idea but might not have traction because it would be too difficult to implement, too confusing, or would contradict old code.
Here is an old paper from 2003 n1449. The rationale seems to be related to templates. Warning: there may be typos due to copying over from PDF.
First let’s consider a toy example:
template <typename T> class MyAlloc {/*...*/}; template <typename T, class A> class MyVector {/*...*/}; template <typename T> struct Vec { typedef MyVector<T, MyAlloc<T> > type; }; Vec<int>::type p; // sample usage
The fundamental problem with this idiom, and the main motivating fact for this proposal, is that the idiom causes the template parameters to appear in non-deducible context. That is, it will not be possible to call the function foo below without explicitly specifying template arguments.
template <typename T> void foo (Vec<T>::type&);
So, the syntax is somewhat ugly. We would rather avoid the nested
::type
We’d prefer something like the following:template <typename T> using Vec = MyVector<T, MyAlloc<T> >; //defined in section 2 below Vec<int> p; // sample usage
Note that we specifically avoid the term “typedef template” and introduce the new syntax involving the pair “using” and “=” to help avoid confusion: we are not defining any types here, we are introducing a synonym (i.e. alias) for an abstraction of a type-id (i.e. type expression) involving template parameters. If the template parameters are used in deducible contexts in the type expression then whenever the template alias is used to form a template-id, the values of the corresponding template parameters can be deduced – more on this will follow. In any case, it is now possible to write generic functions which operate on
Vec<T>
in deducible context, and the syntax is improved as well. For example we could rewrite foo as:template <typename T> void foo (Vec<T>&);
We underscore here that one of the primary reasons for proposing template aliases was so that argument deduction and the call to
foo(p)
will succeed.
The follow-up paper n1489 explains why using
instead of using typedef
:
It has been suggested to (re)use the keyword typedef — as done in the paper [4] — to introduce template aliases:
template<class T> typedef std::vector<T, MyAllocator<T> > Vec;
That notation has the advantage of using a keyword already known to introduce a type alias. However, it also displays several disavantages among which the confusion of using a keyword known to introduce an alias for a type-name in a context where the alias does not designate a type, but a template;
Vec
is not an alias for a type, and should not be taken for a typedef-name. The nameVec
is a name for the familystd::vector< [bullet] , MyAllocator< [bullet] > >
– where the bullet is a placeholder for a type-name. Consequently we do not propose the “typedef” syntax. On the other hand the sentencetemplate<class T> using Vec = std::vector<T, MyAllocator<T> >;
can be read/interpreted as: from now on, I’ll be using
Vec<T>
as a synonym forstd::vector<T, MyAllocator<T> >
. With that reading, the new syntax for aliasing seems reasonably logical.
I think the important distinction is made here, aliases instead of types. Another quote from the same document:
An alias-declaration is a declaration, and not a definition. An alias- declaration introduces a name into a declarative region as an alias for the type designated by the right-hand-side of the declaration. The core of this proposal concerns itself with type name aliases, but the notation can obviously be generalized to provide alternate spellings of namespace-aliasing or naming set of overloaded functions (see ? 2.3 for further discussion). [My note: That section discusses what that syntax can look like and reasons why it isn't part of the proposal.] It may be noted that the grammar production alias-declaration is acceptable anywhere a typedef declaration or a namespace-alias-definition is acceptable.
Summary, for the role of using
:
namespace PO = boost::program_options
and using PO = ...
equivalent)A typedef declaration can be viewed as a special case of non-template alias-declaration
. It's an aesthetic change, and is considered identical in this case.namespace std
into the global scope), member functions, inheriting constructorsIt cannot be used for:
int i;
using r = i; // compile-error
Instead do:
using r = decltype(i);
Naming a set of overloads.
// bring cos into scope
using std::cos;
// invalid syntax
using std::cos(double);
// not allowed, instead use Bjarne Stroustrup function pointer alias example
using test = std::cos(double);
you can do it this way
private Button btn;
btn = (Button)findViewById(R.id.button2);
btn.performClick();
Typescript solution based off of @krzysztof-dabrowski 's answer
export interface HoursMinutes {
hours: number;
minutes: number;
}
export function convert12to24(time12h: string): HoursMinutes {

if (hours === '12') {
hours = '00';
}
if (minutes.length === 1) {
minutes = `0${minutes}`;
}
if (modifier.toUpperCase() === 'PM') {
hours = parseInt(hours, 10) + 12 + '';

Overwrite the brand class, either in the bootstrap.css or a new CSS file, as below -
.brand
{
background: url(images/logo.png) no-repeat left center;
height: 20px;
width: 100px;
}
and your html should look like -
<div class="container-fluid">
<a class="brand" href="index.html"></a>
</div>
You need to write a document.write object:
document.write('<script type="text/javascript" src="file.js" ></script>');
and place it in your main javascript file
It's much more easier to add only the event for mousedown:
private void MyDataGridView_MouseDown(object sender, MouseEventArgs e)
{
if (e.Button == MouseButtons.Right)
{
var hti = MyDataGridView.HitTest(e.X, e.Y);
MyDataGridView.Rows[hti.RowIndex].Selected = true;
MyDataGridView.Rows.RemoveAt(rowToDelete);
MyDataGridView.ClearSelection();
}
}
This is easier. Of cource you have to init your mousedown-event as already mentioned with:
this.MyDataGridView.MouseDown += new System.Windows.Forms.MouseEventHandler(this.MyDataGridView_MouseDown);
in your constructor.
There are a number of good answers already, but some are out of date and none of them are entirely complete. In particular, most of them will remove dependencies but still leave it up to you to remove the originally-targeted formula afterwards. The posted one-liners can also be tedious to work with if you want to uninstall more than one formula at a time.
Here is a Bourne-compatible shell function (without any known Bashisms) that takes a list of formulae, removes each one's dependencies, removes all copies of the formula itself, and then reinstalls any missing dependencies.
unbrew () {
local formula
for formula in "$@"; do
brew deps "$formula" |
xargs brew uninstall --ignore-dependencies --force
brew uninstall --force "$formula"
done
brew missing | cut -f2 -d: | sort -u | xargs brew install
}
It was tested on Homebrew 1.7.4.
This works on all standard formulae that I tested. It does not presently handle casks, but neither will it complain loudly if you attempt to unbrew a cask with the same name as a standard formula (e.g. MacVim).
Use a Temp Table or a Table variable, e.g.
select 'A' as [value]
into #tmp
union
select 'B'
union
select 'C'
and then
SELECT
blah
FROM foo
WHERE myField IN (select [value] from #tmp)
or
SELECT
f.blah
FROM foo f INNER JOIN #tmp t ON f.myField = t.[value]
use below code , change proper database name and user name and then take that output and execute in SSMS. FOR SQL 2005 ABOVE
USE <database_name>
select 'GRANT EXECUTE ON ['+name+'] TO [userName] '
from sys.objects
where type ='P'
and is_ms_shipped = 0
If you need to remove multiple elements from array without converting it to List
nor creating additional array, you may do it in O(n) not dependent on count of items to remove.
Here, a
is initial array, int... r
are distinct ordered indices (positions) of elements to remove:
public int removeItems(Object[] a, int... r) {
int shift = 0;
for (int i = 0; i < a.length; i++) {
if (shift < r.length && i == r[shift]) // i-th item needs to be removed
shift++; // increment `shift`
else
a[i - shift] = a[i]; // move i-th item `shift` positions left
}
for (int i = a.length - shift; i < a.length; i++)
a[i] = null; // replace remaining items by nulls
return a.length - shift; // return new "length"
}
Small testing:
String[] a = {"0", "1", "2", "3", "4"};
removeItems(a, 0, 3, 4); // remove 0-th, 3-rd and 4-th items
System.out.println(Arrays.asList(a)); // [1, 2, null, null, null]
In your task, you can first scan array to collect positions of "a", then call removeItems()
.
Solved my own problem. This line:
BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream()));
needs to be:
BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream(), "UTF-8"));
or since Java 7:
BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream(), StandardCharsets.UTF_8));
I have created a tool that can accomplish automatic semantic versioning based on the tags in commit messages, known as change types. This closely follows the Angular Commit Message Convention along with the Semantic Versioning Specification.
You could use this tool to automatically change the version in the package.json using the npm CLI (this is described here).
In addition, it can create a changelog from these commits and also has a menu (with a spell checker for commit messages) for creating commits based on the change type. I highly recommend checking it out and reading to docs to see everything that can be accomplished with it.
I wrote the tool because I couldn't find anything that suited my needs for my CICD Pipeline to automate semantic versioning. I'd rather focus on what the actual changes are than what the version should be and that's where my tool saves the day.
For more information on the rationale for the tool, please see this.
In my case not was working out, finally i restarted my oracle and TNS listener and everything worked. Was struggling for 2 days.
In order to exit from the app on pressing back button you have to first clear all the top activities and then start the ACTION_MAIN of android phone
So, you have to write all these code only which is mentioned below :
Note : In your case MainActivity get replaced by YourActivity
@Override
public void onBackPressed() {
new AlertDialog.Builder(this)
.setTitle("Really Exit?")
.setMessage("Are you sure you want to exit?")
.setNegativeButton(android.R.string.no, null)
.setPositiveButton(android.R.string.yes, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
MainActivity.super.onBackPressed();
quit();
}
}).create().show();
}
public void quit() {
Intent start = new Intent(Intent.ACTION_MAIN);
start.addCategory(Intent.CATEGORY_HOME);
start.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
start.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(start);
}
You can use the DataColumnCollection of Your datatable to check if the column is in the collection.
Something like:
DataColumnCollection Columns = dtItems.Columns;
if (Columns.Contains(ColNameToCheck))
{
row["ColNameToCheck"] = "Checked";
}
time_t
is just typedef
for 8 bytes (long long/__int64
) which all compilers and OS's understand. Back in the days, it used to be just for long int
(4 bytes) but not now. If you look at the time_t
in crtdefs.h
you will find both implementations but the OS will use long long
.
I believe you are having the same problem here.
The sheet must be active before you can select a range on it.
Also, don't omit the sheet name qualifier:
Sheets("BxWsn Simulation").Select
Sheets("BxWsn Simulation").Range("Result").Select
Or,
With Sheets("BxWsn Simulation")
.Select
.Range("Result").Select
End WIth
which is the same.
There can be multiple ways. slicing will be fastest. Adding one more which uses .index() method:
>>> l1 = [1,5,2,3,5,1,7,43]
>>> [i for i in l1 if l1.index(i)+1==len(l1)]
[43]

You shouldn't blindly trust everything posted on stackoverflow. The comment in Jens code is incorrect, the parameter doesn't control whether exceptions are thrown or not.
MSDN is very clear what that parameter controls, have you read it? http://msdn.microsoft.com/en-us/library/dd321703(v=vs.110).aspx
If
throwOnFirstException
is true, an exception will immediately propagate out of the call to Cancel, preventing the remaining callbacks and cancelable operations from being processed. IfthrowOnFirstException
is false, this overload will aggregate any exceptions thrown into anAggregateException
, such that one callback throwing an exception will not prevent other registered callbacks from being executed.
The variable name is also wrong because Cancel is called on CancellationTokenSource
not the token itself and the source changes state of each token it manages.
A list of values quickly? Or even a list of objects!
I am just a beginner at the C# language but I like using

There's just too many ways to store items
You can use the from
and size
parameters to page through all your data. This could be very slow depending on your data and how much is in the index.
http://www.elastic.co/guide/en/elasticsearch/reference/current/search-request-from-size.html
If you've definitely got an absolute path, use Path.GetDirectoryName(path)
.
If you might only get a relative name, use new FileInfo(path).Directory.FullName
.
Note that Path
and FileInfo
are both found in the namespace System.IO
.
implode(' ',$array);
I solved this by changing the expression to:
reverse( 'django-admin', args=["%s/%s/%s/" % (app_label, model_name, object_id)] )
This requires/assumes that the root url conf has a name for the "admin" url handler, mainly that name is "django-admin",
i.e. in the root url conf:
url(r'^admin/(.*)', admin.site.root, name='django-admin'),
It seems to be working, but I'm not sure of its cleanness.
Using pandas: pd.Timestamp("today").strftime("%m/%d/%Y")
Bear in mind that using WaitForSingleObject
can get you into trouble in this scenario. The following is snipped from a tip on my website:
The problem arises because your application has a window but isn't pumping messages. If the spawned application invokes SendMessage with one of the broadcast targets (HWND_BROADCAST or HWND_TOPMOST), then the SendMessage won't return to the new application until all applications have handled the message - but your app can't handle the message because it isn't pumping messages.... so the new app locks up, so your wait never succeeds.... DEADLOCK.
If you have absolute control over the spawned application, then there are measures you can take, such as using SendMessageTimeout rather than SendMessage (e.g. for DDE initiations, if anybody is still using that). But there are situations which cause implicit SendMessage broadcasts over which you have no control, such as using the SetSysColors API for instance.
The only safe ways round this are:
MsgWaitForMultipleObjects
API.jps -lV
is most useful. Prints just pid and qualified main class name:
2472 com.intellij.idea.Main
11111 sun.tools.jps.Jps
9030 play.server.Server
2752 org.jetbrains.idea.maven.server.RemoteMavenServer
Remove these two lines:
xmlHttp.setRequestHeader("Content-length", params.length);
xmlHttp.setRequestHeader("Connection", "close");
XMLHttpRequest isn't allowed to set these headers, they are being set automatically by the browser. The reason is that by manipulating these headers you might be able to trick the server into accepting a second request through the same connection, one that wouldn't go through the usual security checks - that would be a security vulnerability in the browser.
I second that.
Dex2jar will generate a WORKING jar, which you can add as your project source, with the xmls you got from apktool.
However, JDGUI generates .java files which have ,more often than not, errors.
It has got something to do with code obfuscation I guess.

A screenshot of the output of the above code:
I found that that when I have two Get methods, one parameterless and one with a complex type as a parameter that I got the same error. I solved this by adding a dummy parameter of type int, named Id, as my first parameter, followed by my complex type parameter. I then added the complex type parameter to the route template. The following worked for me.
First get:
public IEnumerable<SearchItem> Get()
{
...
}
Second get:
public IEnumerable<SearchItem> Get(int id, [FromUri] List<string> layers)
{
...
}
WebApiConfig:
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{id}/{layers}",
defaults: new { id = RouteParameter.Optional, layers RouteParameter.Optional }
);
I managed to download the file generated by the rest API URL much easier with this kind of code which worked just fine on my local:
import React, {Component} from "react";
import {saveAs} from "file-saver";
class MyForm extends Component {
constructor(props) {
super(props);
this.handleSubmit = this.handleSubmit.bind(this);
}
handleSubmit(event) {
event.preventDefault();
const form = event.target;
let queryParam = buildQueryParams(form.elements);
let url = 'http://localhost:8080/...whatever?' + queryParam;
fetch(url, {
method: 'GET',
headers: {
// whatever
},
})
.then(function (response) {
return response.blob();
}
)
.then(function(blob) {
saveAs(blob, "yourFilename.xlsx");
})
.catch(error => {
//whatever
})
}
render() {
return (
<form onSubmit={this.handleSubmit} id="whateverFormId">

<tr>
<td>
<input type="text" key="myText" name="myText" id="myText"/>
</td>
<td><input key="startDate" name="from" id="startDate" type="date"/></td>

</tr>

</table>
</form>
);
}
}
function buildQueryParams(formElements) {
let queryParam = "";
//do code here
return queryParam;
}
export default MyForm;
The query can be written slightly simpler, like this:
DECLARE @T INT = 2
SELECT CASE
WHEN @T < 1 THEN 'less than one'
WHEN @T = 1 THEN 'one'
ELSE 'greater than one'
END T
HTML and XML entities are just a way of referencing a Unicode code-point in a way that reliably works regardless of the encoding of the actual page, making them useful for using esoteric Unicode characters in a page using 7-bit ASCII or some other encoding scheme, ideally on a one-off basis. They're also used to escape the <
, >
, "
and &
characters as these are reserved in SGML.
Anyway, Unicode has a number of tick/check characters, as per Wikipedia ( http://en.wikipedia.org/wiki/Tick_(check_mark) ).
Ideally you should save/store your HTML in a Unicode format like UTF-8 or 16, thus obviating the need to use HTML entities to represent a Unicode character. Nonetheless use: ✔
✔.

I had the same problem. I am using jquery-validation as an npm module and the fix for me was to require the module at the start of my js file:
require('jquery-validation');
You can add this code:
function parseBool(str) {
if (str.length == null) {
return str == 1 ? true : false;
} else {
return str == "true" ? true : false;
}
}
Works like this:
parseBool(1) //true
parseBool(0) //false
parseBool("true") //true
parseBool("false") //false
These were two methods I tried. Both are fine to use.
int main() {
int size,temp;
cin>>size;
vector<int> ar(size);
//method 1
for(auto i=0;i<size;i++)
{ cin>>temp;
ar.insert(ar.begin()+i,temp);
}
for (auto i:ar)
cout <<i<<" ";
//method 2
for(int i=0;i<size;i++)
{
cin>>ar[i];
}
for (auto i:ar)
cout <<i<<" ";
return 0;
}
Multiple insert/ batch insert is now supported by CodeIgniter.
$data = array(

'title' => 'Another title' ,
'name' => 'Another Name' ,
'date' => 'Another date'
)
);
$this->db->insert_batch('mytable', $data);
// Produces: INSERT INTO mytable (title, name, date) VALUES ('My title', 'My name', 'My date'), ('Another title', 'Another name', 'Another date')
string.Format("{0:hh:mm:ss tt}", DateTime.Now)
This should give you the string value of the time. tt should append the am/pm.

List
The easiest way, that I know of, is to create a fixed-size single element List
with Arrays.asList(T...)
like
// Returns a List backed by a varargs T.
return Arrays.asList(s);
List
If it needs vary in size you can construct an ArrayList
and the fixed-sizeList
like
return new ArrayList<String>(Arrays.asList(s));
and (in Java 7+) you can use the diamond operator <>
to make it
return new ArrayList<>(Arrays.asList(s));
Collections can return a list with a single element with list being immutable:
Collections.singletonList(s)
The benefit here is IDEs code analysis doesn't warn about single element asList(..) calls.
If you know that you're using the same context and not detaching any entities, you can make a generic version like this:
public void InsertOrUpdate<T>(T entity, DbContext db) where T : class
{
if (db.Entry(entity).State == EntityState.Detached)
db.Set<T>().Add(entity);
// If an immediate save is needed, can be slow though
// if iterating through many entities:
db.SaveChanges();
}
db
can of course be a class field, or the method can be made static and an extension, but this is the basics.
Add the following to the eclipse.ini
:
-vm
Java_Home_Variable\bin\javaw.exe
In my Case its
-vm
H:\usr\java\jdk1.6.0_16\bin\javaw.exe
Encountered a similar problem today. Did not see my fix listed here, so I thought I'd share.
Root could not erase a file.
I did my research. Turns out there's something called an immutable bit.
# lsattr /path/file
----i-------- /path/file
#
This bit being configured prevents even root from modifying/removing it.
To remove this I did:
# chattr -i /path/file
After that I could rm the file.
In reverse, it's a neat trick to know if you have something you want to keep from being gone.

As the automatical zoom-in (with no zoom-out) is still annonying on iPhone, here's a JavaScript based on dlo's suggestion working with focus/blur.
Zooming is disabled as soon as a text input is fucused and re-anabled when the input is left.
Note: Some users may not apprechiate editing texts in a small text input! Therefore, I personally prefer to change the input's text size during editing (see code below).
<script type="text/javascript">
<!--
function attachEvent(element, evtId, handler) {
if (element.addEventListener) {
element.addEventListener(evtId, handler, false);
} else if (element.attachEvent) {
var ieEvtId = "on"+evtId;
element.attachEvent(ieEvtId, handler);
} else {
var legEvtId = "on"+evtId;
element[legEvtId] = handler;
}
}
function onBeforeZoom(evt) {
var viewportmeta = document.querySelector('meta[name="viewport"]');
if (viewportmeta) {
viewportmeta.content = "user-scalable=0";
}
}
function onAfterZoom(evt) {
var viewportmeta = document.querySelector('meta[name="viewport"]');
if (viewportmeta) {
viewportmeta.content = "width=device-width, user-scalable=1";
}
}
function disableZoom() {
// Search all relevant input elements and attach zoom-events
var inputs = document.getElementsByTagName("input");
for (var i=0; i<inputs.length; i++) {
attachEvent(inputs[i], "focus", onBeforeZoom);
attachEvent(inputs[i], "blur", onAfterZoom);
}
}
if (navigator.userAgent.match(/iPhone/i) || navigator.userAgent.match(/iPad/i)) {
attachEvent(window, "load", disableZoom);
}
// -->
</script>
The following code will change an input's text size to 16 pixel (calculated, i.e., in the current zoom size) during the element has the focus. iPhone will therefore not automatically zoom-in.
Note: The zoom factor is calculated based on window.innerWidth and iPhone's display with of 320 pixels. This will only be valid for iPhone in portrait mode.
<script type="text/javascript">
<!--

var legEvtId = "on"+evtId;
element[legEvtId] = handler;

if (!evt) {
evt = window.event;

return sender;

function onBeforeZoom(evt) {
var zoom = 320 / window.innerWidth;
var element = getSender(evt);
element.style.fontSize = Math.ceil(16 / zoom) + "px";
}
function onAfterZoom(evt) {
var element = getSender(evt);
element.style.fontSize = "";
}
function disableZoom() {
// Search all relevant input elements and attach zoom-events
var inputs = document.getElementsByTagName("input");

}
}

Without using 'length' you can do it like this:
if ($('input[type=checkbox]').is(":checked")) {
//any one is checked
}
else {
//none is checked
}
HashMap
is implemented by Hash Table while TreeMap
is implemented by Red-Black tree
. The main difference between HashMap
and TreeMap
actually reflect the main difference between a Hash
and a Binary Tree
, that is, when iterating, TreeMap guarantee can the key order which is determined by either element's compareTo() method or a comparator set in the TreeMap's constructor.
Take a look at following diagram.
For all struggling around with the #selector in Swift 3 or Swift 4, here a full code example:
// WE NEED A CLASS THAT SHOULD RECEIVE NOTIFICATIONS
class MyReceivingClass {
// ---------------------------------------------
// INIT -> GOOD PLACE FOR REGISTERING
// ---------------------------------------------
init() {
// WE REGISTER FOR SYSTEM NOTIFICATION (APP WILL RESIGN ACTIVE)
// Register without parameter
NotificationCenter.default.addObserver(self, selector: #selector(MyReceivingClass.handleNotification), name: .UIApplicationWillResignActive, object: nil)
// Register WITH parameter
NotificationCenter.default.addObserver(self, selector: #selector(MyReceivingClass.handle(withNotification:)), name: .UIApplicationWillResignActive, object: nil)
}
// ---------------------------------------------
// DE-INIT -> LAST OPTION FOR RE-REGISTERING
// ---------------------------------------------
deinit {
NotificationCenter.default.removeObserver(self)
}
// either "MyReceivingClass" must be a subclass of NSObject OR selector-methods MUST BE signed with '@objc'
// ---------------------------------------------
// HANDLE NOTIFICATION WITHOUT PARAMETER
// ---------------------------------------------
@objc func handleNotification() {
print("RECEIVED ANY NOTIFICATION")
}
// ---------------------------------------------
// HANDLE NOTIFICATION WITH PARAMETER
// ---------------------------------------------
@objc func handle(withNotification notification : NSNotification) {
print("RECEIVED SPECIFIC NOTIFICATION: \(notification)")
}
}
In this example we try to get POSTs from AppDelegate (so in AppDelegate implement this):
// ---------------------------------------------
// WHEN APP IS GOING TO BE INACTIVE
// ---------------------------------------------
func applicationWillResignActive(_ application: UIApplication) {
print("POSTING")
// Define identifiyer
let notificationName = Notification.Name.UIApplicationWillResignActive
// Post notification
NotificationCenter.default.post(name: notificationName, object: nil)
}
Depending on what you are doing, system() or popen() may be perfect. Use system() if the Python script has no output, or if you want the Python script's output to go directly to the browser. Use popen() if you want to write data to the Python script's standard input, or read data from the Python script's standard output in php. popen() will only let you read or write, but not both. If you want both, check out proc_open(), but with two way communication between programs you need to be careful to avoid deadlocks, where each program is waiting for the other to do something.
If you want to pass user supplied data to the Python script, then the big thing to be careful about is command injection. If you aren't careful, your user could send you data like "; evilcommand ;" and make your program execute arbitrary commands against your will.
escapeshellarg() and escapeshellcmd() can help with this, but personally I like to remove everything that isn't a known good character, using something like
preg_replace('/[^a-zA-Z0-9]/', '', $str)
Late to the party, but I think it is a useful answer.
flatMap
would be the shortest way to do it.
Stream.of(objects).flatMap(o->(o instanceof Client)?Stream.of((Client)o):Stream.empty())
If o
is a Client
then create a Stream with a single element, otherwise use the empty stream. These streams will then be flattened into a Stream<Client>
.
In the event someone needs a generic version of mattsven's answer (as I did), here it is:
$('select').each(function() {
$(this).data('lastSelected', $(this).find('option:selected'));
});
$('select').change(function() {
if(my_condition) {
$(this).data('lastSelected').attr('selected', true);
}
});
$('select').click(function() {
$(this).data('lastSelected', $(this).find('option:selected'));
});
To understand pid files, refer this DOC
Some times there are certain applications that require additional support of extra plugins and utilities. So it keeps track of these utilities and plugin process running ids using this pid file for reference.
That is why whenever you restart an application all necessary plugins and dependant apps must be restarted since the pid file will become stale.
In a Firebird database the AFTER myOtherColumn
does not work but you can try re-positioning the column using:
ALTER TABLE name ALTER column POSITION new_position
I guess it may work in other cases as well.
Another way of doing that is:
String date = dateAndTime.substring(0, dateAndTime.indexOf(" "));
I'm not exactly certain, but I think this might be faster/use less memory than using the .split()
method.
I found that when I was reading strings in from a .plist
file, occurrences of "\n"
were parsed as "\\n"
. The solution for me was to replace occurrences of "\\n"
with "\n"
. For example, given an instance of NSString
named myString
read in from my .plist
file, I had to call...
myString = [myString stringByReplacingOccurrencesOfString:@"\\n" withString:@"\n"];
... before assigning it to my UILabel
instance...
myLabel.text = myString;
DroidParts has ImageFetcher that requires zero configuration to get started.
Clone DroidPartsGram for an example:
I don't use Gradle in anger myself (just a toy project so far) [author means they have used Gradle on only a toy project so far, not that Gradle is a toy project - see comments], but I'd say that the reasons one would consider using it would be because of the frustrations of Ant and Maven.
In my experience Ant is often write-only (yes I know it is possible to write beautifully modular, elegant builds, but the fact is most people don't). For any non-trivial projects it becomes mind-bending, and takes great care to ensure that complex builds are truly portable. Its imperative nature can lead to replication of configuration between builds (though macros can help here).
Maven takes the opposite approach and expects you to completely integrate with the Maven lifecycle. Experienced Ant users find this particularly jarring as Maven removes many of the freedoms you have in Ant. For example there's a Sonatype blog that enumerates many of the Maven criticisms and their responses.
The Maven plugin mechanism allows for very powerful build configurations, and the inheritance model means you can define a small set of parent POMs encapsulating your build configurations for the whole enterprise and individual projects can inherit those configurations, leaving them lightweight. Maven configuration is very verbose (though Maven 3 promises to address this), and if you want to do anything that is "not the Maven way" you have to write a plugin or use the hacky Ant integration. Note I happen to like writing Maven plugins but appreciate that many will object to the effort involved.
Gradle promises to hit the sweet spot between Ant and Maven. It uses Ivy's approach for dependency resolution. It allows for convention over configuration but also includes Ant tasks as first class citizens. It also wisely allows you to use existing Maven/Ivy repositories.
So if you've hit and got stuck with any of the Ant/Maven pain points, it is probably worth trying Gradle out, though in my opinion it remains to be seen if you wouldn't just be trading known problems for unknown ones. The proof of the pudding is in the eating though so I would reserve judgment until the product is a little more mature and others have ironed out any kinks (they call it bleeding edge for a reason). I'll still be using it in my toy projects though, It's always good to be aware of the options.
I came here when trying to count the files in a data set of approximately 10,000 folders with approximately 10,000 files each. The problem with many of the approaches is that they implicitly stat 100 million files, which takes ages.
I took the liberty to extend the approach by Christopher Schultz so it supports passing directories via arguments (his recursive approach uses stat as well).
Put the following into file dircnt_args.c
:
#include <stdio.h>
#include <dirent.h>
int main(int argc, char *argv[]) {
DIR *dir;
struct dirent *ent;
long count;
long countsum = 0;
int i;
for(i=1; i < argc; i++) {
dir = opendir(argv[i]);
count = 0;
while((ent = readdir(dir)))
++count;
closedir(dir);
printf("%s contains %ld files\n", argv[i], count);
countsum += count;
}
printf("sum: %ld\n", countsum);
return 0;
}
After a gcc -o dircnt_args dircnt_args.c
you can invoke it like this:
dircnt_args /your/directory/*
On 100 million files in 10,000 folders, the above completes quite quickly (approximately 5 minutes for the first run, and followup on cache: approximately 23 seconds).
The only other approach that finished in less than an hour was ls
with about 1 min on cache: ls -f /your/directory/* | wc -l
. The count is off by a couple of newlines per directory though...
Other than expected, none of my attempts with find
returned within an hour :-/
I had a similarly strange problem with a file from the program e-prime (edat -> SPSS conversion), but then I discovered that there are many additional encodings you can use. this did the trick for me:
tbl <- read.delim("dir/file.txt", fileEncoding="UCS-2LE")
Often you will want to specify a manifest, like so:
jar -cvfm myJar.jar myManifest.txt myApp.class
Which reads: "create verbose jarFilename manifestFilename", followed by the files you want to include. Verbose means print messages about what it's doing.
Note that the name of the manifest file you supply can be anything, as jar
will automatically rename it and put it into the right directory within the jar file.
It appears that the Facebook app handles this intent incorrectly. The most reliable way seems to be to use the Facebook API for Android.
The SDK is at this link: http://github.com/facebook/facebook-android-sdk
Under 'usage', there is this:
Display a Facebook dialog.
The SDK supports several WebView html dialogs for user interactions, such as creating a wall post. This is intended to provided quick Facebook functionality without having to implement a native Android UI and pass data to facebook directly though the APIs.
This seems like the best way to do it -- display a dialog that will post to the wall. The only issue is that they may have to log in first
here is what you need to install the SQL profiler http://msdn.microsoft.com/en-us/library/bb500441.aspx. However, i would suggest you to read through this one http://blog.sqlauthority.com/2009/08/03/sql-server-introduction-to-sql-server-2008-profiler-2/ if you are looking to do it on your Production Environment. There is another better way to look at the queries watch this one and see if it helps http://www.youtube.com/watch?v=vvziPI5OQyE
in 2020, the accepted answer is kinda out of date since the PageRequest
is deprecated, so you should use code like this :
Pageable page = PageRequest.of(pageable.getPageNumber(), pageable.getPageSize(), Sort.by("id").descending());
return repository.findAll(page);
Actually Java supports 4 methods to parse XML out of the box:
DOM Parser/Builder: The whole XML structure is loaded into memory and you can use the well known DOM methods to work with it. DOM also allows you to write to the document with Xslt transformations. Example:
public static void parse() throws ParserConfigurationException, IOException, SAXException {
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
factory.setValidating(true);
factory.setIgnoringElementContentWhitespace(true);
DocumentBuilder builder = factory.newDocumentBuilder();
File file = new File("test.xml");
Document doc = builder.parse(file);
// Do something with the document here.
}
SAX Parser: Solely to read a XML document. The Sax parser runs through the document and calls callback methods of the user. There are methods for start/end of a document, element and so on. They're defined in org.xml.sax.ContentHandler and there's an empty helper class DefaultHandler.
public static void parse() throws ParserConfigurationException, SAXException {
SAXParserFactory factory = SAXParserFactory.newInstance();
factory.setValidating(true);
SAXParser saxParser = factory.newSAXParser();
File file = new File("test.xml");
saxParser.parse(file, new ElementHandler()); // specify handler
}
StAx Reader/Writer: This works with a datastream oriented interface. The program asks for the next element when it's ready just like a cursor/iterator. You can also create documents with it. Read document:
public static void parse() throws XMLStreamException, IOException {
try (FileInputStream fis = new FileInputStream("test.xml")) {
XMLInputFactory xmlInFact = XMLInputFactory.newInstance();
XMLStreamReader reader = xmlInFact.createXMLStreamReader(fis);
while(reader.hasNext()) {
reader.next(); // do something here
}
}
}
Write document:
public static void parse() throws XMLStreamException, IOException {
try (FileOutputStream fos = new FileOutputStream("test.xml")){
XMLOutputFactory xmlOutFact = XMLOutputFactory.newInstance();
XMLStreamWriter writer = xmlOutFact.createXMLStreamWriter(fos);
writer.writeStartDocument();
writer.writeStartElement("test");
// write stuff
writer.writeEndElement();
}
}
JAXB: The newest implementation to read XML documents: Is part of Java 6 in v2. This allows us to serialize java objects from a document. You read the document with a class that implements a interface to javax.xml.bind.Unmarshaller (you get a class for this from JAXBContext.newInstance). The context has to be initialized with the used classes, but you just have to specify the root classes and don't have to worry about static referenced classes. You use annotations to specify which classes should be elements (@XmlRootElement) and which fields are elements(@XmlElement) or attributes (@XmlAttribute, what a surprise!)
public static void parse() throws JAXBException, IOException {
try (FileInputStream adrFile = new FileInputStream("test")) {
JAXBContext ctx = JAXBContext.newInstance(RootElementClass.class);
Unmarshaller um = ctx.createUnmarshaller();
RootElementClass rootElement = (RootElementClass) um.unmarshal(adrFile);
}
}
Write document:
public static void parse(RootElementClass out) throws IOException, JAXBException {
try (FileOutputStream adrFile = new FileOutputStream("test.xml")) {
JAXBContext ctx = JAXBContext.newInstance(RootElementClass.class);
Marshaller ma = ctx.createMarshaller();
ma.marshal(out, adrFile);
}
}
Examples shamelessly copied from some old lecture slides ;-)
Edit: About "which API should I use?". Well it depends - not all APIs have the same capabilities as you see, but if you have control over the classes you use to map the XML document JAXB is my personal favorite, really elegant and simple solution (though I haven't used it for really large documents, it could get a bit complex). SAX is pretty easy to use too and just stay away from DOM if you don't have a really good reason to use it - old, clunky API in my opinion. I don't think there are any modern 3rd party libraries that feature anything especially useful that's missing from the STL and the standard libraries have the usual advantages of being extremely well tested, documented and stable.
By Timestamp
, I presume you mean java.sql.Timestamp
. You will notice that this class has a constructor that accepts a long
argument. You can parse this using the DateFormat
class:
DateFormat dateFormat = new SimpleDateFormat("dd/MM/yyyy");
Date date = dateFormat.parse("23/09/2007");
long time = date.getTime();
new Timestamp(time);
In my case $(document).ready(function() was missing. Try this.
$(document).ready(function(){
("#table tr").click(function(){
$(this).addClass('selected').siblings().removeClass('selected');
var value=$(this).find('td:first').html();
alert(value);
});
$('.ok').on('click', function(e){
alert($("#table tr.selected td:first").html());
});
});
First you have to ensure that there is a SMTP server listening on port 25.
To look whether you have the service, you can try using TELNET client, such as:
C:\> telnet localhost 25
(telnet client by default is disabled on most recent versions of Windows, you have to add/enable the Windows component from Control Panel. In Linux/UNIX usually telnet client is there by default.
$ telnet localhost 25
If it waits for long then time out, that means you don't have the required SMTP service. If successfully connected you enter something and able to type something, the service is there.
If you don't have the service, you can use these:
If you are sure that you already have the service, may be the SMTP requires additional security credentials. If you can tell me what SMTP server listening on port 25 I may be able to tell you more.
You better use CSS for that, after all, this is what CSS is for. If you don't want to do that, go with Dorwand's answer.
"tail" is command to display the last part of a file, using proper available switches helps us to get more specific output. the most used switch for me is -n and -f
SYNOPSIS
tail [-F | -f | -r] [-q] [-b number | -c number | -n number] [file ...]
Here
-n number : The location is number lines.
-f : The -f option causes tail to not stop when end of file is reached, but rather to wait for additional data to be appended to the input. The -f option is ignored if the standard input is a pipe, but not if it is a FIFO.
Retrieve last 100 lines logs
To get last static 100 lines
tail -n 100 <file path>
To get real time last 100 lines
tail -f -n 100 <file path>
Try out this example, the onclick is still called from your HTML, and event bubbling is stopped.
<div class="expandable-panel-heading">
<h2>
<a id="ancherComplaint" href="#addComplaint" onclick="markActiveLink(this);event.stopPropagation();">ABC</a>
</h2>
</div>
You can also use convert to make the date searchable using LIKE. For example,
select convert(VARCHAR(40),create_date,121) , * from sys.objects where convert(VARCHAR(40),create_date,121) LIKE '%17:34%'
Consider using a higher dimensional datastructure (a Panel), rather than storing an array in your column:
In [11]: p = pd.Panel({'df': df, 'csc': csc})
In [12]: p.df
Out[12]:
0 1 2
0 1 2 3
1 4 5 6
2 7 8 9
In [13]: p.csc
Out[13]:
0 1 2
0 0 1 0
1 0 0 1
2 1 0 0
Look at cross-sections etc, etc, etc.
In [14]: p.xs(0)
Out[14]:
csc df
0 0 1
1 1 2
2 0 3
remap
is an option that makes mappings work recursively. By default it is on and I'd recommend you leave it that way. The rest are mapping commands, described below:
:map
and :noremap
are recursive and non-recursive versions of the various mapping commands. For example, if we run:
:map j gg (moves cursor to first line)
:map Q j (moves cursor to first line)
:noremap W j (moves cursor down one line)
Then:
j
will be mapped to gg
.Q
will also be mapped to gg
, because j
will be expanded for the recursive mapping.W
will be mapped to j
(and not to gg
) because j
will not be expanded for the non-recursive mapping.Now remember that Vim is a modal editor. It has a normal mode, visual mode and other modes.
For each of these sets of mappings, there is a mapping that works in normal, visual, select and operator modes (:map
and :noremap
), one that works in normal mode (:nmap
and :nnoremap
), one in visual mode (:vmap
and :vnoremap
) and so on.
For more guidance on this, see:
:help :map
:help :noremap
:help recursive_mapping
:help :map-modes
According to my humble opinion and my work experience with git, staging area is not the same as index. I may be wrong of course, but as I said, my experience in using git and my logic tell me, that index is a structure that follows your changes to your working area(local repository) that are not excluded by ignoring settings and staging area is to keep files that are already confirmed to be committed, aka files in index on which add command was run on. You don't notice and realize that "slight" difference, because you use
git commit -a -m "comment"
adding indexed and cached files to stage area and committing in one command or using IDEs like IDEA for that too often. And cache is that what keeps changes in indexed files.
If you want to remove file from index that has not been added to staging area before, options proposed before match for you, but...
If you have done that already, you will need to use
Git restore --staged <file>
And, please, don't ask me where I was 10 years ago... I missed you, this answer is for further generations)
If you have a number, for example 65, and if you want to get the corresponding ASCII character, you can use the chr
function, like this
>>> chr(65)
'A'
similarly if you have 97,
>>> chr(97)
'a'
EDIT: The above solution works for 8 bit characters or ASCII characters. If you are dealing with unicode characters, you have to specify unicode value of the starting character of the alphabet to ord
and the result has to be converted using unichr
instead of chr
.
>>> print unichr(ord(u'\u0B85'))
?
>>> print unichr(1 + ord(u'\u0B85'))
?
NOTE: The unicode characters used here are of the language called "Tamil", my first language. This is the unicode table for the same http://www.unicode.org/charts/PDF/U0B80.pdf
It is returning the array, but all returning something (including an Array) does is just what it sounds like: returns the value. In your case, you are getting the value of numbers()
, which happens to be an array (it could be anything and you would still have this issue), and just letting it sit there.
When a function returns anything, it is essentially replacing the line in which it is called (in your case: numbers();
) with the return value. So, what your main
method is really executing is essentially the following:
public static void main(String[] args) {
{1,2,3};
}
Which, of course, will appear to do nothing. If you wanted to do something with the return value, you could do something like this:
public static void main(String[] args){
int[] result = numbers();
for (int i=0; i<result.length; i++) {
System.out.print(result[i]+" ");
}
}
$percentage = 50;
$totalWidth = 350;
$new_width = ($percentage / 100) * $totalWidth;
I wrote a method for this sometime back. It deletes the specified directory and returns true if the directory deletion was successful.
/**
* Delets a dir recursively deleting anything inside it.
* @param dir The dir to delete
* @return true if the dir was successfully deleted
*/
public static boolean deleteDirectory(File dir) {
if(! dir.exists() || !dir.isDirectory()) {
return false;
}
String[] files = dir.list();
for(int i = 0, len = files.length; i < len; i++) {
File f = new File(dir, files[i]);
if(f.isDirectory()) {
deleteDirectory(f);
}else {
f.delete();
}
}
return dir.delete();
}

From the DOCS
Formats a number as text. Group sizing and separator and other locale-specific configurations are based on the active locale.
SYNTAX:
number_expression | number[:digitInfo[:locale]]
where expression
is a number:
digitInfo
is a string which has a following format:
{minIntegerDigits}.{minFractionDigits}-{maxFractionDigits}
=if(a1="","1","0")
In this formula if the cell is empty then the result would be 1
else it would be 0
Android Studio 3.5.3 It works with this configuration.
I think this resource should suffice for a moderate XML save/load: Read/Write XML using C#.
My task was to store musical notation. I choose XML, because I guess .NET has matured enough to allow easy solution for the task. I was right :)
This is my song file prototype:
<music judul="Kupu-Kupu yang Lucu" pengarang="Ibu Sud" tempo="120" birama="4/4" nadadasar="1=F" biramapembilang="4" biramapenyebut="4">
<not angka="1" oktaf="0" naikturun="" nilai="1"/>
<not angka="2" oktaf="0" naikturun="" nilai="0.5"/>
<not angka="5" oktaf="1" naikturun="/" nilai="0.25"/>
<not angka="2" oktaf="0" naikturun="\" nilai="0.125"/>
<not angka="1" oktaf="0" naikturun="" nilai="0.0625"/>
</music>
That can be solved quite easily:
For Save to File:
private void saveToolStripMenuItem_Click(object sender, EventArgs e)
{
saveFileDialog1.Title = "Save Song File";
saveFileDialog1.Filter = "Song Files|*.xsong";
if (saveFileDialog1.ShowDialog() == DialogResult.OK)
{
FileStream fs = new FileStream(saveFileDialog1.FileName, FileMode.Create);
XmlTextWriter w = new XmlTextWriter(fs, Encoding.UTF8);
w.WriteStartDocument();
w.WriteStartElement("music");
w.WriteAttributeString("judul", Program.music.getTitle());
w.WriteAttributeString("pengarang", Program.music.getAuthor());
w.WriteAttributeString("tempo", Program.music.getTempo()+"");
w.WriteAttributeString("birama", Program.music.getBirama());
w.WriteAttributeString("nadadasar", Program.music.getNadaDasar());
w.WriteAttributeString("biramapembilang", Program.music.getBiramaPembilang()+"");
w.WriteAttributeString("biramapenyebut", Program.music.getBiramaPenyebut()+"");
for (int i = 0; i < listNotasi.Count; i++)
{
CNot not = listNotasi[i];
w.WriteStartElement("not");
w.WriteAttributeString("angka", not.getNot() + "");
w.WriteAttributeString("oktaf", not.getOktaf() + "");
String naikturun="";
if(not.isTurunSetengah())naikturun="\\";
else if(not.isNaikSetengah())naikturun="/";
w.WriteAttributeString("naikturun",naikturun);
w.WriteAttributeString("nilai", not.getNilaiNot()+"");
w.WriteEndElement();
}
w.WriteEndElement();
w.Flush();
fs.Close();
}
}
For load file:
openFileDialog1.Title = "Open Song File";
openFileDialog1.Filter = "Song Files|*.xsong";
if (openFileDialog1.ShowDialog() == DialogResult.OK)
{
FileStream fs = new FileStream(openFileDialog1.FileName, FileMode.Open);
XmlTextReader r = new XmlTextReader(fs);
while (r.Read())
{
if (r.NodeType == XmlNodeType.Element)
{
if (r.Name.ToLower().Equals("music"))
{
Program.music = new CMusic(r.GetAttribute("judul"),
r.GetAttribute("pengarang"),
r.GetAttribute("birama"),
Convert.ToInt32(r.GetAttribute("tempo")),
r.GetAttribute("nadadasar"),
Convert.ToInt32(r.GetAttribute("biramapembilang")),
Convert.ToInt32(r.GetAttribute("biramapenyebut")));
}
else
if (r.Name.ToLower().Equals("not"))
{
CNot not = new CNot(Convert.ToInt32(r.GetAttribute("angka")), Convert.ToInt32(r.GetAttribute("oktaf")));
if (r.GetAttribute("naikturun").Equals("/"))
{
not.setNaikSetengah();
}
else if (r.GetAttribute("naikturun").Equals("\\"))
{
not.setTurunSetengah();
}
not.setNilaiNot(Convert.ToSingle(r.GetAttribute("nilai")));
listNotasi.Add(not);
}
}
else
if (r.NodeType == XmlNodeType.Text)
{
Console.WriteLine("\tVALUE: " + r.Value);
}
}
}
}
}
The easiest way to convert an ISO-8859-1 string to UTF-8 string.
private static String convertIsoToUTF8(String example) throws UnsupportedEncodingException {
return new String(example.getBytes("ISO-8859-1"), "utf-8");
}
If we want to convert an UTF-8 string to ISO-8859-1 string.
private static String convertUTF8ToISO(String example) throws UnsupportedEncodingException {
return new String(example.getBytes("utf-8"), "ISO-8859-1");
}
Moreover, a method that converts an ISO-8859-1 string to UTF-8 string without using the constructor of class String.
public static String convertISO_to_UTF8_personal(String strISO_8859_1) {
String res = "";
int i = 0;
for (i = 0; i < strISO_8859_1.length() - 1; i++) {
char ch = strISO_8859_1.charAt(i);
char chNext = strISO_8859_1.charAt(i + 1);
if (ch <= 127) {
res += ch;
} else if (ch == 194 && chNext >= 128 && chNext <= 191) {
res += chNext;
} else if(ch == 195 && chNext >= 128 && chNext <= 191){
int resNum = chNext + 64;
res += (char) resNum;
} else if(ch == 194){
res += (char) 173;
} else if(ch == 195){
res += (char) 224;
}
}
char ch = strISO_8859_1.charAt(i);
if (ch <= 127 ){
res += ch;
}
return res;
}
}
That method is based on enconding utf-8 to iso-8859-1 of this website. Encoding utf-8 to iso-8859-1
The then
method returns a pending promise which can be resolved asynchronously by the return value of a result handler registered in the call to then
, or rejected by throwing an error inside the handler called.
So calling AuthUser
will not suddenly log the user in synchronously, but returns a promise whose then registered handlers will be called after the login succeeds ( or fails). I would suggest triggering all login processing by a then
clause of the login promise. E.G. using named functions to highlight the sequence of flow:
let AuthUser = data => { // just the login promise
return google.login(data.username, data.password);
};
AuthUser(data).then( processLogin).catch(loginFail);
function processLogin( token) {
// do logged in stuff:
// enable, initiate, or do things after login
}
function loginFail( err) {
console.log("login failed: " + err);
}
The new
keyword allocates memory on the Java heap. The heap is the main pool of memory, accessible to the whole of the application. If there is not enough memory available to allocate for that object, the JVM attempts to reclaim some memory from the heap with a garbage collection. If it still cannot obtain enough memory, an OutOfMemoryError
is thrown, and the JVM exits.
The heap is split into several different sections, called generations. As objects survive more garbage collections, they are promoted into different generations. The older generations are not garbage collected as often. Because these objects have already proven to be longer lived, they are less likely to be garbage collected.
When objects are first constructed, they are allocated in the Eden Space. If they survive a garbage collection, they are promoted to Survivor Space, and should they live long enough there, they are allocated to the Tenured Generation. This generation is garbage collected much less frequently.
There is also a fourth generation, called the Permanent Generation, or PermGen. The objects that reside here are not eligible to be garbage collected, and usually contain an immutable state necessary for the JVM to run, such as class definitions and the String constant pool. Note that the PermGen space is planned to be removed from Java 8, and will be replaced with a new space called Metaspace, which will be held in native memory. reference:http://www.programcreek.com/2013/04/jvm-run-time-data-areas/

You can use C++ function for doing this.
std::string repeat(const std::string& input, size_t num)
{
std::ostringstream os;
std::fill_n(std::ostream_iterator<std::string>(os), num, input);
return os.str();
}
In my case namespaces
parameter was not matching the namespace of the controller.
public override void RegisterArea(AreaRegistrationContext context)
{
context.MapRoute(
"Admin_default",
"Admin/{controller}/{action}/{id}",
new {controller = "Home", action = "Index", id = UrlParameter.Optional },
namespaces: new[] { "Web.Areas.Admin.Controllers" }
);
}
You can do it like this:
def powerset(x):
m=[]
if not x:
m.append(x)
else:
A = x[0]
B = x[1:]
for z in powerset(B):
m.append(z)
r = [A] + z
m.append(r)
return m
print(powerset([1, 2, 3, 4]))
Output:
[[], [1], [2], [1, 2], [3], [1, 3], [2, 3], [1, 2, 3], [4], [1, 4], [2, 4], [1, 2, 4], [3, 4], [1, 3, 4], [2, 3, 4], [1, 2, 3, 4]]
As of bootstrap 4, the answer is to simply set navbar-dark in the nav element, which will set the text and links to a light theme .
<nav class="navbar navbar-dark">
There is no shorthand in VBA unfortunately, The closest you will get is a purely visual thing using the :
continuation character if you want it on one line for readability;
Dim clientToTest As String: clientToTest = clientsToTest(i)
Dim clientString As Variant: clientString = Split(clientToTest)
Hint (summary of other answers/comments): Works with objects too (Excel 2010):
Dim ws As Worksheet: Set ws = ActiveWorkbook.Worksheets("Sheet1")
Dim ws2 As New Worksheet: ws2.Name = "test"
Set its layout_height="0dp"
*, add a blank View
beneath it (or blank ImageView
or just a FrameLayout
) with a layout_height
also equal to 0dp
, and set both Views to have a layout_weight="1"
This will stretch each View equally as it fills the screen. Since both have the same weight, each will take 50% of the screen.
*See adamp's comment for why that works and other really helpful tidbits.
The PHP function echo() prints out its input to the web server response.
echo("Hello World!");
prints out Hello World! to the web server response.
echo("<prev>");
prints out the tag to the web server response.
echo do not require valid HTML tags. You can use PHP to print XML, images, excel, HTML and so on.
<prev> is not a HTML tag. Is is a valid XML tag, but since I don't know what page you are working in, i cannot tell you what it is. Maybe it is the root tag of a XML page, or a miswritten <pre> tag.
I know its pretty old but I just encounter the problem and there is what I saw in the SQL doc :
[For best results when using BETWEEN with date or time values,] use CAST() to explicitly convert the values to the desired data type. Examples: If you compare a DATETIME to two DATE values, convert the DATE values to DATETIME values. If you use a string constant such as '2001-1-1' in a comparison to a DATE, cast the string to a DATE.
I assume it's better to use STR_TO_DATE since they took the time to make a function just for that and also the fact that i found this in the BETWEEN doc...
What @forhas and @HRgiger did also worked for me. I am using spring-data-mongodb
instead of jpa
.
However, for mongodb bindings, you should not remove the version of mongodb reference xsd, just keep it with version: http://www.springframework.org/schema/data/mongo/spring-mongo-1.0.xsd
. context
and beans
versions should be removed.
In response to the post starting:
If you want to use this with command line or function arguments...
with the code:
size=${#1}
There might be the case where you just want to check for a zero length argument and have no need to store a variable. I believe you can use this sort of syntax:
if [ -z "$1" ]; then
#zero length argument
else
#non-zero length
fi
See GNU and wooledge for a more complete list of Bash conditional expressions.
If you want to use default value for a DateTime parameter in a method, you can only use default(DateTime).
The following line will not compile:
private void MyMethod(DateTime syncedTime = DateTime.MinValue)
This line will compile:
private void MyMethod(DateTime syncedTime = default(DateTime))
MySQL default port is 3306 but it may be unavailable for some reasons, try to restart your machine. Also sesrch for your MySQL configuration file (should be called "my.cnf") and check if the used port is 3306 or 3307, if is 3307 you can change it to 3306 and then reboot your MySQL server.
As suggested in an earlier answer, we need to include two additional files - jquery.fileupload-process.js
and then jquery.fileupload-validate.js
However as I need to perform some additional ajax calls while adding a file, I am subscribing to the fileuploadadd
event to perform those calls. Regarding such a usage the author of this plugin suggested the following
Please have a look here: https://github.com/blueimp/jQuery-File-Upload/wiki/Options#wiki-callback-options
Adding additional event listeners via bind (or on method with jQuery 1.7+) method is the preferred option to preserve callback settings by the jQuery File Upload UI version.
Alternatively, you can also simply start the processing in your own callback, like this: https://github.com/blueimp/jQuery-File-Upload/blob/master/js/jquery.fileupload-process.js#L50
Using the combination of the two suggested options, the following code works perfectly for me
$fileInput.fileupload({
url: 'upload_url',
type: 'POST',
dataType: 'json',
autoUpload: false,
disableValidation: false,
maxFileSize: 1024 * 1024,
messages: {
maxFileSize: 'File exceeds maximum allowed size of 1MB',
}
});
$fileInput.on('fileuploadadd', function(evt, data) {
var $this = $(this);
var validation = data.process(function () {
return $this.fileupload('process', data);
});
validation.done(function() {
makeAjaxCall('some_other_url', { fileName: data.files[0].name, fileSizeInBytes: data.files[0].size })
.done(function(resp) {
data.formData = data.formData || {};
data.formData.someData = resp.SomeData;
data.submit();
});
});
validation.fail(function(data) {
console.log('Upload error: ' + data.files[0].error);
});
});
Though this isn't a DIRECT answer to your question, I just encountered a similar problem, and thought I'd mentioned it:
I had an instance where it was instantiating a new (no doubt very inefficent) record for data.frame (a result of recursive searching) and it was giving me the same error.
I had this:
return(
data.frame(
user_id = gift$email,
sourced_from_agent_id = gift$source,
method_used = method,
given_to = gift$account,
recurring_subscription_id = NULL,
notes = notes,
stringsAsFactors = FALSE
)
)
turns out... it was the = NULL. When I switched to = NA, it worked fine. Just in case anyone else with a similar problem hits THIS post as I did.
In your package.json
in the "dependencies"
section add moment:
"dependencies": {
"moment": "^2.15.2",
...
}
In the component where you would like to use moment, import it:
<script>
import moment from 'moment'
...
And in the same component add a computed property:
computed: {
timestamp: function () {
return moment(this.<model>.attributes['created-at']).format('YYYY-MM-DD [at] hh:mm')
}
}
And then in the template of this component:
<p>{{ timestamp }}</p>
For vector graphics, ImageMagick has both a render resolution and an output size that are independent of each other.
Try something like
convert -density 300 image.eps -resize 1024x1024 image.jpg
Which will render your eps at 300dpi. If 300 * width > 1024, then it will be sharp. If you render it too high though, you waste a lot of memory drawing a really high-res graphic only to down sample it again. I don't currently know of a good way to render it at the "right" resolution in one IM command.
The order of the arguments matters! The -density X
argument needs to go before image.eps
because you want to affect the resolution that the input file is rendered at.
This is not super obvious in the manpage for convert
, but is hinted at:
SYNOPSIS
convert [input-option] input-file [output-option] output-file
Since 2019 you can now use the new functionality called Github package registry.

If anyone wonders how to this for clustermap CorrGrids (part of a given seaborn example):
import seaborn as sns
import matplotlib.pyplot as plt
sns.set(context="paper", font="monospace")
# Load the datset of correlations between cortical brain networks
df = sns.load_dataset("brain_networks", header=[0, 1, 2], index_col=0)
corrmat = df.corr()
# Set up the matplotlib figure
f, ax = plt.subplots(figsize=(12, 9))
# Draw the heatmap using seaborn
g=sns.clustermap(corrmat, vmax=.8, square=True)
rotation = 90
for i, ax in enumerate(g.fig.axes): ## getting all axes of the fig object
ax.set_xticklabels(ax.get_xticklabels(), rotation = rotation)
g.fig.show()
In this state:
The thread is reading and processing rows for a SELECT statement, and sending data to the client.
Because operations occurring during this this state tend to perform large amounts of disk access (reads).
That's why it takes more time to complete and so is the longest-running state over the lifetime of a given query.
The following seems to work:
import datetime
print (datetime.datetime.now().strftime("%y"))
The datetime.data object that it wants is on the "left" of the dot rather than the right. You need an instance of the datetime to call the method on, which you get through now()
Quite simple with a closure:
def map = [
'iPhone':'iWebOS',
'Android':'2.3.3',
'Nokia':'Symbian',
'Windows':'WM8'
]
map.each{ k, v -> println "${k}:${v}" }
It seems that your question is quite answered, but i have an approach that may simplify you case:
I had a similar issue trying to return string data from mysql, even configuring both database and php to return strings formatted to utf-8. The only way i got the error was actually returning them from the database.
Finally, sailing through the web i found a really easy way to deal with it:
Giving that you can save all those types of string data in your mysql in different formats and collations, what you only need to do is, right at your php connection file, set the collation to utf-8, like this:
$connection = new mysqli($server, $user, $pass, $db);
$connection->set_charset("utf8");
Wich means that first you save the data in any format or collation and you convert it only at the return to your php file.
Hope it was helpful!
If you are accessing scoped beans within Spring Web MVC, i.e. within a request that is processed by the Spring DispatcherServlet, or DispatcherPortlet, then no special setup is necessary: DispatcherServlet and DispatcherPortlet already expose all relevant state.
If you are runnning outside of Spring MVC ( Not processed by DispatchServlet) you have to use the RequestContextListener
Not just ContextLoaderListener
.
Add the following in your web.xml
<listener>
<listener-class>
org.springframework.web.context.request.RequestContextListener
</listener-class>
</listener>
That will provide session to Spring in order to maintain the beans in that scope
Update :
As per other answers , the @Controller
only sensible when you are with in Spring MVC Context, So the @Controller is not serving actual purpose in your code. Still you can inject your beans into any where with session scope / request scope ( you don't need Spring MVC / Controller to just inject beans in particular scope) .
Update :
RequestContextListener exposes the request to the current Thread only.
You have autowired ReportBuilder in two places
1. ReportPage
- You can see Spring injected the Report builder properly here, because we are still in Same web Thread. i did changed the order of your code to make sure the ReportBuilder injected in ReportPage like this.
log.info("ReportBuilder name: {}", reportBuilder.getName());
reportController.getReportData();
i knew the log should go after as per your logic , just for debug purpose i added .
2. UselessTasklet
- We got exception , here because this is different thread created by Spring Batch , where the Request is not exposed by RequestContextListener
.
You should have different logic to create and inject ReportBuilder
instance to Spring Batch ( May Spring Batch Parameters and using Future<ReportBuilder>
you can return for future reference)
You can also find the use of lambda expressions in writing generic codes to act on your methods.
For example: Generic function to calculate the time taken by a method call. (i.e. Action
in here)
public static long Measure(Action action)
{
Stopwatch sw = new Stopwatch();
sw.Start();
action();
sw.Stop();
return sw.ElapsedMilliseconds;
}
And you can call the above method using the lambda expression as follows,
var timeTaken = Measure(() => yourMethod(param));
Expression allows you to get return value from your method and out param as well
var timeTaken = Measure(() => returnValue = yourMethod(param, out outParam));
You can use an anonymous function to pass the matches to your function:
$result = preg_replace_callback(
"/\{([<>])([a-zA-Z0-9_]*)(\?{0,1})([a-zA-Z0-9_]*)\}(.*)\{\\1\/\\2\}/isU",
function($m) { return CallFunction($m[1], $m[2], $m[3], $m[4], $m[5]); },
$result
);
Apart from being faster, this will also properly handle double quotes in your string. Your current code using /e
would convert a double quote "
into \"
.
Abstract classes and interfaces are semantically different, although their usage can overlap.
An abstract class is generally used as a building basis for similar classes. Implementation that is common for the classes can be in the abstract class.
An interface is generally used to specify an ability for classes, where the classes doesn't have to be very similar.
Using the out keyword with a return type of bool, can sometimes reduce code bloat and increase readability. (Primarily when the extra info in the out param is often ignored.) For instance:
var result = DoThing();
if (result.Success)
{
result = DoOtherThing()
if (result.Success)
{
result = DoFinalThing()
if (result.Success)
{
success = true;
}
}
}
vs:
var result;
if (DoThing(out result))
{
if (DoOtherThing(out result))
{
if (DoFinalThing(out result))
{
success = true;
}
}
}
I had ran into this similar problem as well. In my case, my resolution is quite different. Here's my spring context xml file:
...
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="

http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd">
...
I'm not specifying any xsd version as I want spring to use the latest xsd version inside spring dependencies. The spring version my application used was spring-beans-4.3.1.RELEASE.jar:4.3.1.RELEASE and when I assembly my application into jar, all spring dependencies exist in my classpath. However, I received following error during startup of my spring application context:
org.xml.sax.SAXParseException: schema_reference.4: Failed to read schema document 'http://www.springframework.org/schema/beans/spring-beans.xsd', because 1) could not find the document; 2) the document could not be read; 3) the root element of the document is not <xsd:schema>.
After some hard time troubleshooting, I found the issue is due to the index.list inside the META-INF folder of my jar file. With index.list file, spring namespace handlers cannot be located to parse the spring application context xml correctly. You can read more about this spring issue SPR-5705
By removing indexing from my maven-jar-plugin, I manage to resolve the issue. Hope this will save some times for people having the same problem.
try it ! also can calculate NA's data!
df <- data.frame(a1=1:10, a2=11:20)
df %>% summarise_each(funs( mean( .,na.rm = TRUE)))
# a1 a2
# 5.5 15.5

The ES6 way to split a string into an array character-wise is by using the spread operator. It is simple and nice.
array = [...myString];
Example:
let myString = "Hello world!"
array = [...myString];
console.log(array);
// another example:
console.log([..."another splitted text"]);

This is just a suggestion, it might not work and I'm prepared to be called on this.
This will generate false positives, but hopefully not false negatives.
Resize both of the images so that they are the same size (I assume that the ratios of widths to lengths are the same in both images).
Compress a bitmap of both images with a lossless compression algorithm (e.g. gzip).
Find pairs of files that have similar file sizes. For instance, you could just sort every pair of files you have by how similar the file sizes are and retrieve the top X.
As I said, this will definitely generate false positives, but hopefully not false negatives. You can implement this in five minutes, whereas the Porikil et. al. would probably require extensive work.
How about try some different mirrors? If you are in China, I highly recommend you try:
sudo pip install --index https://pypi.mirrors.ustc.edu.cn/simple/ opencv-contrib-python
If not, just replace the url address to some other mirrors you like! Good luck.

You have to mark the single letter as optional too:
([A-Z]{1})? +.*? +
or make the whole part optional
(([A-Z]{1}) +.*? +)?
Do you mean how long is the array itself, or how many customerids are in it?
Because the answer to the first question is easy: 5 (or if you don't want to hard-code it, Ben Stott's answer).
But the answer to the other question cannot be automatically determined. Presumably you have allocated an array of length 5, but will initially have 0 customer IDs in there, and will put them in one at a time, and your question is, "how many customer IDs have I put into the array?"
C can't tell you this. You will need to keep a separate variable, int numCustIds
(for example). Every time you put a customer ID into the array, increment that variable. Then you can tell how many you have put in.
I found that it was better to add to the table row by row if your table has a primary key. Inserting the entire table at once creates a conflict on the auto increment.
Here's my stored Proc
CREATE PROCEDURE dbo.usp_InsertRowsIntoTable
@Year int,
@TeamName nvarchar(50),
AS
INSERT INTO [dbo.TeamOverview]
(Year,TeamName)
VALUES (@Year, @TeamName);
RETURN
I put this code in a loop for every row that I need to add to my table:
insertRowbyRowIntoTable(Convert.ToInt16(ddlChooseYear.SelectedValue), name);
And here is my Data Access Layer code:
public void insertRowbyRowIntoTable(int ddlValue, string name)
{
SqlConnection cnTemp = null;
string spName = null;
SqlCommand sqlCmdInsert = null;
try
{
cnTemp = helper.GetConnection();
using (SqlConnection connection = cnTemp)
{
if (cnTemp.State != ConnectionState.Open)
cnTemp.Open();
using (sqlCmdInsert = new SqlCommand(spName, cnTemp))
{
spName = "dbo.usp_InsertRowsIntoOverview";
sqlCmdInsert = new SqlCommand(spName, cnTemp);
sqlCmdInsert.CommandType = CommandType.StoredProcedure;
sqlCmdInsert.Parameters.AddWithValue("@Year", ddlValue);
sqlCmdInsert.Parameters.AddWithValue("@TeamName", name);
sqlCmdInsert.ExecuteNonQuery();
}
}
}
catch (Exception ex)
{
throw ex;
}
finally
{
if (sqlCmdInsert != null)
sqlCmdInsert.Dispose();
if (cnTemp.State == ConnectionState.Open)
cnTemp.Close();
}
}
To count numbers or dates that meet a single test (such as equal to, greater than, less than, greater than or equal to, or less than or equal to), use the COUNTIF function. In Excel 2007 and later, to count numbers or dates that fall within a range (such as greater than 9000 and at the same time less than 22500), you can use the COUNTIFS function. If you are using Excel 2003 or earlier, you can use the SUMPRODUCT function to count the numbers that fall within a range (COUNTIFS was introduced in Excel 2007).

The answer above was 90% of what I needed, but returned a Uri instead of a regular path for me.
As explained in the MSDN forums post, How to convert URI path to normal filepath?, I used the following:
// Get normal filepath of this assembly's permanent directory
var path = new Uri(
System.IO.Path.GetDirectoryName(
System.Reflection.Assembly.GetExecutingAssembly().CodeBase)
).LocalPath;
I propose using Task<T>
instead of Thread
; it allows multiple parameters and executes really fine.
Here is a working example:
public static void Main()
{
List<Task> tasks = new List<Task>();
Console.WriteLine("Awaiting threads to finished...");
string par1 = "foo";
string par2 = "boo";
int par3 = 3;
for (int i = 0; i < 1000; i++)
{
tasks.Add(Task.Run(() => Calculate(par1, par2, par3)));
}
Task.WaitAll(tasks.ToArray());
Console.WriteLine("All threads finished!");
}
static bool Calculate1(string par1, string par2, int par3)
{
lock(_locker)
{
//...
return true;
}
}
// if need to lock, use this:
private static Object _locker = new Object();"
static bool Calculate2(string par1, string par2, int par3)
{
lock(_locker)
{
//...
return true;
}
}
... or just resultlist.RemoveAt(1)
if you know exactly the index.

While building the project on Unix/Linux platform, set Maven options syntax as below. Notice that single qoutation signs, not double qoutation.
export MAVEN_OPTS='-Xmx512m -XX:MaxPermSize=128m'
Command works only if "use" -command has been first used to define the database where working in. Table column renaming syntax using DATABASE.TABLE throws error and does not work. Version: HIVE 0.12.

Just to throw a spanner in the works - i'm of the opinion that you should never use the img tag. HTML was meant for content, not visual style. all the images on your page should come from the CSS, leaving your HTML code pure. (even if it does take a bit longer to build)
Architecture is more like integrating various functionalities of a System to achive one goal of the System as a whole, while design addresses each functional requirements.
For example, take example of MVVM, which is an architectural pattern. For notification functionality, MVVM uses observer Pattern, which in turn is a design pattern,
I guess this is what you want:
l = range(100)
index = 0
for i in l:
print i,
try:
print l.pop(index+1),
print l.pop(index+1)
except:
pass
index += 1
It is quite handy to code when the number of item to be popped is a run time decision. But it runs with very a bad efficiency and the code is hard to maintain.
Open the output window.
Look for the little icon on the very right-hand side of the toolbar that starts with the text "Show output from:" in it. It looks like a small window with a carriage return icon. When you hover over it Visual Studio should display "Toggle Word Wrap" near your mouse pointer.
Click that icon.
You now have learned something that was so painfully obvious I feel embarrassed for not knowing this long ago and thus have chosen to pay my dues and share my answer with others so they don't suffer the same agony I have.
Seriously, this is really useful for those with small screens. I have a small Lilliput USB monitor that is good for small tool windows, Skype IM, etc. It works great for putting the output window on, except that it sucks having to always sideways scroll. After just putting up with sideways scroll for months I finally decided to see if I could make it word wrap. The answer was so easy but the amount of time/effort it saves is tremendous.
Because you are calling that function instead of passing the function to onClick, change that line to this:
<button type="submit" onClick={() => { this.props.removeTaskFunction(todo) }}>Submit</button>
=>
called Arrow Function, which was introduced in ES6, and will be supported on React 0.13.3 or upper.
You can use for loop
int[] random_numbers = {10, 30, 44, 21, 51, 21, 61, 24, 14}
int array_length = random_numbers.Length;
for (int i = 0; i < array_length; i++){
if(i == array_length - 1){
Console.Write($"{random_numbers[i]}\n");
} else{
Console.Write($"{random_numbers[i]}, ");
}
}
If you're looking for an integral result, you can just determine the highest bit set in the value and return its position.
Both perform the same function but driver.get(); seems more popular.
driver.navigate().to();
is best used when you are already in the middle of a script and you want to redirect from current URL to a new one. For the sake of differentiating your codes, you can use driver.get();
to launch the first URL after opening a browser instance, albeit both will work either way.
Take a look also to the do { ... }
command since gnuplot 4.6 as it is very powerful:
do for [t=0:50] {
outfile = sprintf('animation/bessel%03.0f.png',t)
set output outfile
splot u*sin(v),u*cos(v),bessel(u,t/50.0) w pm3d ls 1
}
As mentioned by Bunkar typeid(T).name is implementation defined.
To avoid this issue you can use Boost.TypeIndex library.
For example:
boost::typeindex::type_id<T>().pretty_name() // human readable
If you get an unexpected MemoryError
and you think you should have plenty of RAM available, it might be because you are using a 32-bit python installation.
The easy solution, if you have a 64-bit operating system, is to switch to a 64-bit installation of python.
The issue is that 32-bit python only has access to ~4GB of RAM. This can shrink even further if your operating system is 32-bit, because of the operating system overhead.
You can learn more about why 32-bit operating systems are limited to ~4GB of RAM here: https://superuser.com/questions/372881/is-there-a-technical-reason-why-32-bit-windows-is-limited-to-4gb-of-ram

Normally when you try to select a node using xpath your xpath-engine will return null or equivalent if the node doesn't exists.
xpath: "/Consumers/Consumer/DataSources/Credit/CreditReport/AttachedXml"
If your using xsl check out this question for an answer:
You may use parseInt
:
int id = Integer.parseInt(jsonObj.get("id"));
or better and more directly the getInt method :
int id = jsonObj.getInt("id");
If you are using HttpClient 4.5.x
, your code can be similar to the following:
SSLContext sslContext = new SSLContextBuilder().loadTrustMaterial(null,
TrustSelfSignedStrategy.INSTANCE).build();
SSLConnectionSocketFactory sslSocketFactory = new SSLConnectionSocketFactory(
sslContext, NoopHostnameVerifier.INSTANCE);
HttpClient httpClient = HttpClients.custom()
.setDefaultCookieStore(new BasicCookieStore())
.setSSLSocketFactory(sslSocketFactory)
.build();
For the legend, you can use this
plt.setp(g._legend.get_title(), fontsize=20)
Where g is your facetgrid object returned after you call the function making it.
You can simply add show.legend=FALSE
to geom to suppress the corresponding legend
The way you're writing your print statement is unnecessarily verbose. There's no need to separate the newline into its own string. This is sufficient.
print "hello.\n";
This realization will probably make your coding easier in general.
In addition to using use feature "say"
or use 5.10.0
or use Modern::Perl
to get the built in say
feature, I'm going to pimp perl5i which turns on a lot of sensible missing Perl 5 features by default.
ALTER TABLE table_name ALTER COLUMN id SET DEFAULT uuid_in((md5((random())::text))::cstring);
After reading @ZuzEL's answer, i used the above code as the default value of the column id and it's working fine.
In similar case I used the following code:
DateTime upperBound = DateTime.Today.AddDays(1); // If today is October 9, then upperBound is set to 2012-10-10 00:00:00
return var _My_ResetSet_Array = _DB
.tbl_MyTable
.Where(x => x.Active == true
&& x.DateTimeValueColumn < upperBound) // Accepts all dates earlier than October 10, time of day doesn't matter here
.Select(x => x);
A change was introduced recently in how Facebook handles session redirects. See "Change in Session Redirect Behavior" in this week's Operation Developer Love blog post for the announcement.
This can be achieved by doing
(a2 & a1) == a2
This creates the intersection of both arrays, returning all elements from a2
which are also in a1
. If the result is the same as a2
, you can be sure you have all elements included in a1
.
This approach only works if all elements in a2
are different from each other in the first place. If there are doubles, this approach fails. The one from Tempos still works then, so I wholeheartedly recommend his approach (also it's probably faster).
Optional arguments only work at the end of a function call. There is no way to specify a value for $y in your function without also specifying $x. Some languages support this via named parameters (VB/C# for example), but not PHP.
You can emulate this if you use an associative array for parameters instead of arguments -- i.e.
function foo(array $args = array()) {
$x = !isset($args['x']) ? 'default x value' : $args['x'];
$y = !isset($args['y']) ? 'default y value' : $args['y'];
...
}
Then call the function like so:
foo(array('y' => 'my value'));
It may help to use a different constructor for Uri.
If you have the server name
string server = "http://www.myserver.com";
and have a relative Uri path to append to it, e.g.
string relativePath = "sites/files/images/picture.png"
When creating a Uri from these two I get the "format could not be determined" exception unless I use the constructor with the UriKind argument, i.e.
// this works, because the protocol is included in the string
Uri serverUri = new Uri(server);
// needs UriKind arg, or UriFormatException is thrown
Uri relativeUri = new Uri(relativePath, UriKind.Relative);
// Uri(Uri, Uri) is the preferred constructor in this case
Uri fullUri = new Uri(serverUri, relativeUri);

I'd like to add a jQuery autocomplete based solution that does the job.
Step 1: Make the list fixed height and scrollable
Get the code from https://jqueryui.com/autocomplete/ "Scrollable" example, setting max height to the list of results so it behaves as a select box.
Step 2: Open the list on focus:
Display jquery ui auto-complete list on focus event
Step 3: Set minimum chars to 0 so it opens no matter how many chars are in the input
Final result:

It's very simple to implement - you should use TestContext
property and TestPropertyAttribute
.
public TestContext TestContext { get; set; }
private List<string> GetProperties()
{
return TestContext.Properties
.Cast<KeyValuePair<string, object>>()
.Where(_ => _.Key.StartsWith("par"))
.Select(_ => _.Value as string)
.ToList();
}
//usage
[TestMethod]
[TestProperty("par1", "http://getbootstrap.com/components/")]
[TestProperty("par2", "http://www.wsj.com/europe")]
public void SomeTest()
{
var pars = GetProperties();
//...
}
I prepared few extension methods to simplify access to the TestContext
property and act like we have several test cases. See example with processing simple test properties here:
[TestMethod]
[TestProperty("fileName1", @".\test_file1")]
[TestProperty("fileName2", @".\test_file2")]
[TestProperty("fileName3", @".\test_file3")]
public void TestMethod3()
{
TestContext.GetMany<string>("fileName").ForEach(fileName =>
{
//Arrange
var f = new FileInfo(fileName);
//Act
var isExists = f.Exists;
//Asssert
Assert.IsFalse(isExists);
});
}
and example with creating complex test objects:
[TestMethod]
//Case 1
[TestProperty(nameof(FileDescriptor.FileVersionId), "673C9C2D-A29E-4ACC-90D4-67C52FBA84E4")]
//...
public void TestMethod2()
{
//Arrange
TestContext.For<FileDescriptor>().Fill(fi => fi.FileVersionId).Fill(fi => fi.Extension).Fill(fi => fi.Name).Fill(fi => fi.CreatedOn, new CultureInfo("en-US", false)).Fill(fi => fi.AccessPolicy)
.ForEach(fileInfo =>
{
//Act
var fileInfoString = fileInfo.ToString();
//Assert
Assert.AreEqual($"Id: {fileInfo.FileVersionId}; Ext: {fileInfo.Extension}; Name: {fileInfo.Name}; Created: {fileInfo.CreatedOn}; AccessPolicy: {fileInfo.AccessPolicy};", fileInfoString);
});
}
Take a look to the extension methods and set of samples for more details.
In case you are using GLib, it has two functions for that, g_strreverse() and g_utf8_strreverse()
Try this....
ul.list-group li {
padding-left: 13px;
position: relative;
}
ul.list-group li:before {
left: 0 !important;
position: absolute;
}
This is how I worked with local swagger JSON

Here is a way to check is virtualization is enabled or disabled by the firmware as suggested by this link in parallels.com.
How to check that Intel VT-x is supported in CPU:
Open Terminal application from Application/Utilities
Copy/paste command bellow
sysctl -a | grep machdep.cpu.features
Mac:~ user$ sysctl -a | grep machdep.cpu.features
kern.exec: unknown type returned
machdep.cpu.features: FPU VME DE PSE TSC MSR PAE MCE CX8 APIC SEP MTRR PGE MCA CMOV PAT CLFSH DS ACPI MMX FXSR SSE SSE2 SS HTT TM SSE3 MON VMX EST TM2 TPR PDCM
If you see VMX entry then CPU supports Intel VT-x feature, but it still may be disabled.

User.where(User.arel_table[:id].gt(200))
Ok I know this a bit of a hack but this is a way to use a variable in a simple query, not a script:
WITH
emplVar AS
(SELECT 1234 AS id FROM dual)
SELECT
*
FROM
employees,
emplVar
WHERE
EmployId=emplVar.id;
You get to run it everywhere.
You may go with Plotly library. It can render interactive 3D plots directly in Jupyter Notebooks.
To do so you first need to install Plotly by running:
pip install plotly
You might also want to upgrade the library by running:
pip install plotly --upgrade
After that in you Jupyter Notebook you may write something like:
# Import dependencies
import plotly
import plotly.graph_objs as go
# Configure Plotly to be rendered inline in the notebook.
plotly.offline.init_notebook_mode()
# Configure the trace.
trace = go.Scatter3d(
x=[1, 2, 3], # <-- Put your data instead
y=[4, 5, 6], # <-- Put your data instead
z=[7, 8, 9], # <-- Put your data instead
mode='markers',
marker={
'size': 10,
'opacity': 0.8,
}
)
# Configure the layout.
layout = go.Layout(
margin={'l': 0, 'r': 0, 'b': 0, 't': 0}
)
data = [trace]
plot_figure = go.Figure(data=data, layout=layout)
# Render the plot.
plotly.offline.iplot(plot_figure)
As a result the following chart will be plotted for you in Jupyter Notebook and you'll be able to interact with it. Of course you will need to provide your specific data instead of suggeseted one.
SQL Server(2012) provides another way to generate script for the SQL Server databases with its objects and data. This script can be used to copy the tables’ schema and data from the source database to the destination one in our case.
SQL Scripting method is useful to generate one single script for the tables’ schema and data, including the indexes and keys. But again this method doesn’t generate the tables’ creation script in the correct order if there are relations between the tables.
This is what I came up with:
$(document).ready(function(){_x000D_
_x000D_
$(".fc-event").each(function(){_x000D_
_x000D_
console.log(this.attributes['data'].nodeValue) _x000D_
});_x000D_
_x000D_
});
_x000D_
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>_x000D_
<div id='external-events'>_x000D_
<h4>Booking</h4>_x000D_
<div class='fc-event' data='00:30:00' >30 Mins</div>_x000D_
<div class='fc-event' data='00:45:00' >45 Mins</div>_x000D_
</div>

In the load events, use Me.Hide
.
In WebBrowser1.DocuementCompleted, use Me.Show
Only the first argument differs:
In more detail...
When an object's method is called, it is automatically given an extra argument self
as its first argument. That is, method
def f(self, x, y)
must be called with 2 arguments. self
is automatically passed, and it is the object itself.
When the method is decorated
@classmethod
def f(cls, x, y)
the automatically provided argument is not self
, but the class of self
.
When the method is decorated
@staticmethod
def f(x, y)
the method is not given any automatic argument at all. It is only given the parameters that it is called with.
classmethod
is mostly used for alternative constructors.staticmethod
does not use the state of the object. It could be a function external to a class. It only put inside the class for grouping functions with similar functionality (for example, like Java's Math
class static methods)class Point
def __init__(self, x, y):
self.x = x
self.y = y
@classmethod
def frompolar(cls, radius, angle):
"""The `cls` argument is the `Point` class itself"""
return cls(radius * cos(angle), radius * sin(angle))
@staticmethod
def angle(x, y):
"""this could be outside the class, but we put it here
just because we think it is logically related to the class."""
return atan(y, x)
p1 = Point(3, 2)
p2 = Point.frompolar(3, pi/4)
angle = Point.angle(3, 2)
The most efficient answer from @morg, unlike foreach
, only works for proper arrays, not hash map objects. This answer avoids the overhead of a conditional statement for every iteration of the loop, as in most of these answers (including the accepted answer) by specifically handling the first and last element, and looping over the middle elements.
The array_keys
function can be used to make the efficient answer work like foreach
:
$keys = array_keys($arr);
$numItems = count($keys);
$i=0;
$firstItem=$arr[$keys[0]];
# Special handling of the first item goes here
$i++;
while($i<$numItems-1){
$item=$arr[$keys[$i]];
# Handling of regular items
$i++;
}
$lastItem=$arr[$keys[$i]];
# Special handling of the last item goes here
$i++;
I haven't done benchmarking on this, but no logic has been added to the loop, which is were the biggest hit to performance happens, so I'd suspect that the benchmarks provided with the efficient answer are pretty close.
If you wanted to functionalize this kind of thing, I've taken a swing at such an iterateList function here. Although, you might want to benchmark the gist code if you're super concerned about efficiency. I'm not sure how much overhead all the function invocation introduces.
Working with MVC websites that use jQuery, I like to make sure AJAX actions within certain event handlers can only be executed once the previous request has completed. I use a "static" jqXHR object variable to achieve this.
Given the following button:
<button type="button" onclick="ajaxAction(this, { url: '/SomeController/SomeAction' })">Action!</button>
I generally use an IIFE like this for my click handler:
var ajaxAction = (function (jqXHR) {
return function (sender, args) {
if (!jqXHR || jqXHR.readyState == 0 || jqXHR.readyState == 4) {
jqXHR = $.ajax({
url: args.url,
type: 'POST',
contentType: 'application/json',
data: JSON.stringify($(sender).closest('form').serialize()),
success: function (data) {
// Do something here with the data.
}
});
}
};
})(null);
The split method of a string is what you need. In fact the tokenizer class in Java is deprecated in favor of Java's string split method.
the easy robust way cross-platform and work in pipenv as well is:
pip freeze
pip uninstall -r requirement
by pipenv:
pipenv run pip freeze
pipenv run pip uninstall -r requirement
but won't update piplock or pipfile so be aware
First of all, you're testing fp
twice. so printf("Error Reading File\n");
never gets executed.
Then, the output of fscanf
should be equal to 2
since you're reading two values.
Apache tomcat is just an only serverlet container it does not support for Enterprise Java application(JEE). JBoss and Glassfish are supporting for JEE application but Glassfish much heavy than JBOSS server : Reference Slide
