Here is a heavy tutorial that has good stuff in it to pick out:
http://mobile.tutsplus.com/tutorials/mobile-web-apps/jquery_android/
I know this is solved and the question was asked long time ago, but as I'm dealing with a similar problem, I would like to give a totally different approach to this:
For arrays it says "An array is an ordered collection of values." at http://www.json.org/ - but objects ("An object is an unordered set of name/value pairs.") aren't ordered.
I wonder why that object is in an array - that implies an order that's not there.
{
"items":
[
{
"WR":"qwe",
"QU":"asd",
"QA":"end",
"WO":"hasd",
"NO":"qwer"
},
]
}
So a solution would be to put the keys in a "real" array and add the data as objects to each key like this:
{
"items":
[
{"WR": {"data": "qwe"}},
{"QU": {"data": "asd"}},
{"QA": {"data": "end"}},
{"WO": {"data": "hasd"}},
{"NO": {"data": "qwer"}}
]
}
So this is an approach that tries to rethink the original modelling and its intent. But I haven't tested (and I wonder) if all involved tools would preserve the order of that original JSON array.
UIAlertController * alert = [UIAlertController
alertControllerWithTitle:@"Are you sure you want to logout?"
message:@""
preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction* yesButton = [UIAlertAction
actionWithTitle:@"Logout"
style:UIAlertActionStyleDestructive
handler:^(UIAlertAction * action)
{
}];
UIAlertAction* noButton = [UIAlertAction
actionWithTitle:@"Cancel"
style:UIAlertActionStyleDefault
handler:^(UIAlertAction * action) {
//Handle no, thanks button
}];
[alert addAction:noButton];
[alert addAction:yesButton];
[self presentViewController:alert animated:YES completion:nil];
On Windows you can use
netstat -na | find "your_port"
to narrow down the results. You can also filter for LISTENING
, ESTABLISHED
, TCP
and such. Mind it's case-sensitive though.
The fastest way i could find out is this :
var myArray = (byte[]) new ImageConverter().ConvertTo(InputImg, typeof(byte[]));
Hope to be useful
Try to use it:
Drop-down box dependent on the option selected in another drop-down box. Use jQuery to change a second select list based on the first select list option.
<asp:HiddenField ID="hdfServiceId" ClientIDMode="Static" runat="server" Value="0" />
<asp:TextBox ID="txtOfferId" CssClass="hidden" ClientIDMode="Static" runat="server" Text="0" />
<asp:HiddenField ID="SelectedhdfServiceId" ClientIDMode="Static" runat="server" Value="0" />
<asp:HiddenField ID="SelectedhdfOfferId" ClientIDMode="Static" runat="server" Value="0" />
<div class="col-lg-2 col-md-2 col-sm-12">
<span>Service</span>
<asp:DropDownList ID="ddlService" ClientIDMode="Static" runat="server" CssClass="form-control">

Worth noting that ||
will also return true
if BOTH A
and B
are true
.
In JavaScript, if you're looking for A
or B
, but not both, you'll need to do something similar to:
if( (A && !B) || (B && !A) ) { ... }
I set the column widths in the HTML markup like so:
<thead>
<tr>
<th style='width: 5%;'>ProjectId</th>
<th style='width: 15%;'>Title</th>
<th style='width: 40%;'>Abstract</th>
<th style='width: 20%;'>Keywords</th>
<th style='width: 10%;'>PaperName</th>
<th style='width: 10%;'>PaperURL</th>
</tr>
</thead>
<tbody>
@foreach (var item in Model)
{
<tr id="@item.ID">
<td>@item.ProjectId</td>
<td>@item.Title</td>
<td>@item.Abstract</td>
<td>@item.Keywords</td>
<td>@item.PaperName</td>
<td>@item.PaperURL</td>
</tr>
}

From a personal blog post, it is not necessary to create a specific JaxbList < T >
object.
Assuming an object with a list of strings:
@XmlRootElement
public class ObjectWithList {
private List<String> list;
@XmlElementWrapper(name="MyList")
@XmlElement
public List<String> getList() {
return list;
}
public void setList(List<String> list) {
this.list = list;
}
}
A JAXB round trip:
public static void simpleExample() throws JAXBException {
List<String> l = new ArrayList<String>();
l.add("Somewhere");
l.add("This and that");
l.add("Something");
// Object with list
ObjectWithList owl = new ObjectWithList();
owl.setList(l);
JAXBContext jc = JAXBContext.newInstance(ObjectWithList.class);
ObjectWithList retr = marshallUnmarshall(owl, jc);
for (String s : retr.getList()) {
System.out.println(s);
} System.out.println(" ");
}
Produces the following:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<objectWithList>
<MyList>
<list>Somewhere</list>
<list>This and that</list>
<list>Something</list>
</MyList>
</objectWithList>
Here is the optimized solution to do it with SimpleDateFormat
parse()
method.
SimpleDateFormat formatter = new SimpleDateFormat(
"EEEE, dd/MM/yyyy/hh:mm:ss");
String strDate = formatter.format(new Date());
try {
Date pDate = formatter.parse(strDate);
} catch (ParseException e) { // note: parse method can throw ParseException
e.printStackTrace();
}
Few things to notice
new Date()
SimpleDateFormat
as
found in the most voted answer for this question. It's just a
waste of memoryException
is a bad practice when we know that the parse
method only stands a chance to throw a ParseException
. We need to be as specific as possible when dealing with Exceptions. You can refer, throws Exception bad practice?In react router 4 the current route is in -
this.props.location.pathname
.
Just get this.props
and verify.
If you still do not see location.pathname
then you should use the decorator withRouter
.
This might look something like this:
import {withRouter} from 'react-router-dom';
const SomeComponent = withRouter(props => <MyComponent {...props}/>);
class MyComponent extends React.Component {
SomeMethod () {
const {pathname} = this.props.location;
}
}
you can use plt.matshow()
instead of plt.imshow()
or you can use seaborn module's heatmap
(see documentation) to plot the confusion matrix
import seaborn as sn
import pandas as pd
import matplotlib.pyplot as plt
array = [[33,2,0,0,0,0,0,0,0,1,3],
[3,31,0,0,0,0,0,0,0,0,0],
[0,4,41,0,0,0,0,0,0,0,1],
[0,1,0,30,0,6,0,0,0,0,1],
[0,0,0,0,38,10,0,0,0,0,0],
[0,0,0,3,1,39,0,0,0,0,4],
[0,2,2,0,4,1,31,0,0,0,2],
[0,1,0,0,0,0,0,36,0,2,0],
[0,0,0,0,0,0,1,5,37,5,1],
[3,0,0,0,0,0,0,0,0,39,0],
[0,0,0,0,0,0,0,0,0,0,38]]
df_cm = pd.DataFrame(array, index = [i for i in "ABCDEFGHIJK"],
columns = [i for i in "ABCDEFGHIJK"])
plt.figure(figsize = (10,7))
sn.heatmap(df_cm, annot=True)
The selected answer didn't work for me, but it's close. I found a tutorial that worked for me and the certificate I obtained from StartCom.
Change the leader and trailer so the file looks similar to this:
-----BEGIN PKCS7-----
[... certificate content here ...]
-----END PKCS7-----
For example, my StartCom certificate began with:
-----BEGIN CERTIFICATE-----
and ended with:
-----END CERTIFICATE-----
Run the following OpenSSL command (works on Ubuntu 14.04.4, as of this writing):
openssl pkcs7 -print_certs –in pkcs7.p7b -out pem.cer
The output is a .cer with the certificate chain.
Reference: http://www.freetutorialssubmit.com/extract-certificates-from-P7B/2206
Implementation is up to compiler developers.
If your question is "what will happen with such declaration" - compiler will set first array element to the value you've provided (0) and all others will be set to zero because it is a default value for omitted array elements.
It should be :
public async Task<ActionResult> GetSomeJsonData()
{
var model = // ... get data or build model etc.
return Json(new { Data = model }, JsonRequestBehavior.AllowGet);
}
or more simply:
return Json(model, JsonRequestBehavior.AllowGet);
I did notice that you are calling GetResources() from another ActionResult which wont work. If you are looking to get JSON back, you should be calling GetResources() from ajax directly...
This answer is for a Material Design horizontal card layout with dynamic height and an image.
To prevent distortion of the image due to the dynamic height of the card, you could use a background placeholder image with blur to adjust for changes in height.
<div>
with class wrapper, which is a flexbox.<a>
, class link, is positioned
relative.<div>
class blur and an <img>
class pic which is the clear image.width: 100%
, but class pic has a higher stack order, i.e., z-index: 2
, which places it above the placeholder.

BTW, if anyone want to get coordinates of element on screen without jQuery, please try this:
function getOffsetTop (el) {
if (el.offsetParent) return el.offsetTop + getOffsetTop(el.offsetParent)
return el.offsetTop || 0
}
function getOffsetLeft (el) {
if (el.offsetParent) return el.offsetLeft + getOffsetLeft(el.offsetParent)
return el.offsetleft || 0
}
function coordinates(el) {
var y1 = getOffsetTop(el) - window.scrollY;
var x1 = getOffsetLeft(el) - window.scrollX;
var y2 = y1 + el.offsetHeight;
var x2 = x1 + el.offsetWidth;
return {
x1: x1, x2: x2, y1: y1, y2: y2
}
}
This is not a particularly good answer as it explains how to run your java code n VS Code and not necessarily a Maven
project, but it worked for me because I could not get around to doing the manual configuration myself. I decided to use this method instead since it is easier and faster.
Install VSCode (and for windows, set your environment variables), then install vscode:extension/vscjava.vscode-java-pack
as detailed above, and then install the code runner extension pack, which basically sets up the whole process (in the background) as explained in the accepted answer above and then provides a play button to run your java code when you're ready.
This was all explained in this video.
Again, this is not the best solution, but if you want to cut to the chase, you may find this answer useful.
Put your image or video in flash format. Works great.
$ cat foo.md
Key 1 | Value 1
Key 2 | Value 2
$ kramdown foo.md
<table>
<tbody>
<tr>
<td>Key 1</td>
<td>Value 1</td>
</tr>
<tr>
<td>Key 2</td>
<td>Value 2</td>
</tr>
</tbody>
</table>
As a Win32 replacement for POSIX systems:
void Sleep(unsigned int milliseconds) {
usleep(milliseconds * 1000);
}
while (1) {
printf(".");
Sleep((unsigned int)(1000.0f/20.0f)); // 20 fps
}
In addition to Adam Rosenfield's answer, I would like to add that ByteBuffer.array()
returns the buffer's underlying byte array, which is not necessarily "trimmed" up to the last character. Extra manipulation will be needed, such as the ones mentioned in this answer; in particular:
byte[] b = new byte[bb.remaining()]
bb.get(b);
Install cscope
. It works very much like ctags
but more powerful. To go to definition, instead of Ctrl + ], do Ctrl + \ + g. Of course you may use both concurrently. But with a big project (say Linux kernel), cscope is miles ahead.
take a look at the plyr
package. Specifically, ddply
ddply(df, .(group), summarise, mean=mean(dt), sum=sum(dt))
None of this work for me, and have many cols on datatable to make % or sm class equals to 12 elements layout on bootstrap.
I was working with datatables Angular 5 and Bootstrap 4, and have many cols in table. The solution for me was in the TH
to add a DIV
element with a specific width. For example for the cols "Person Name" and "Event date" I need a specific width, then put a div
in the col header, the entire col width then resizes to the width specified from the div on the TH
:
<table datatable [dtOptions]="dtOptions" *ngIf="listData" class="table table-hover table-sm table-bordered text-center display" width="100%">
<thead class="thead-dark">
<tr>
<th scope="col">ID </th>
<th scope="col">Value</th>
<th scope="col"><div style="width: 600px;">Person Name</div></th>
<th scope="col"><div style="width: 800px;">Event date</div></th> ...
Form correlation matrix, in my case zdf is the dataframe which i need perform correlation matrix.
corrMatrix =zdf.corr()
corrMatrix.to_csv('sm_zscaled_correlation_matrix.csv');
html = corrMatrix.style.background_gradient(cmap='RdBu').set_precision(2).render()
# Writing the output to a html file.
with open('test.html', 'w') as f:
print('<!DOCTYPE html><html lang="en"><head><meta charset="UTF-8"><meta name="viewport" content="width=device-widthinitial-scale=1.0"><title>Document</title></head><style>table{word-break: break-all;}</style><body>' + html+'</body></html>', file=f)
Then we can take screenshot. or convert html to an image file.
i made a little change to this code to save entry of a radio button but unable to save the text which appears in text box after selecting the radio button.
the code is below:-
<!DOCTYPE html>
<html>
<head>
<style>
form * {
display: block;
margin: 10px;
}
</style>
<script language="Javascript" >
function download(filename, text) {
var pom = document.createElement('a');
pom.setAttribute('href', 'data:text/plain;charset=utf-8,' +
encodeURIComponent(text));
pom.setAttribute('download', filename);
pom.style.display = 'none';
document.body.appendChild(pom);
pom.click();
document.body.removeChild(pom);
}
</script>
</head>
<body>
<form onsubmit="download(this['name'].value, this['text'].value)">
<input type="text" name="name" value="test.txt">
<textarea rows=3 cols=50 name="text">PLEASE WRITE ANSWER HERE. </textarea>
<input type="radio" name="radio" value="Option 1" onclick="getElementById('problem').value=this.value;"> Option 1<br>
<input type="radio" name="radio" value="Option 2" onclick="getElementById('problem').value=this.value;"> Option 2<br>
<form onsubmit="download(this['name'].value, this['text'].value)">
<input type="text" name="problem" id="problem">

Raymond Chen has a really excellent blog post on this:
Peeskillet's lame tutorial for working with JTables in Netbeans GUI Builder
Add a button to the frame somwhere,. This button will be clicked when the user is ready to submit a row
Events -> Action -> actionPerformed
You should see code like the following auto-generated
private void jButton1ActionPerformed(java.awt.event.ActionEvent) {}
The jTable1
will have a DefaultTableModel
. You can add rows to the model with your data
private void jButton1ActionPerformed(java.awt.event.ActionEvent) {
String data1 = something1.getSomething();
String data2 = something2.getSomething();
String data3 = something3.getSomething();
String data4 = something4.getSomething();
Object[] row = { data1, data2, data3, data4 };
DefaultTableModel model = (DefaultTableModel) jTable1.getModel();
model.addRow(row);
// clear the entries.
}
So for every set of data like from a couple text fields, a combo box, and a check box, you can gather that data each time the button is pressed and add it as a row to the model.
Both functions use the os.path.split(path)
function to split the pathname path
into a pair; (head, tail)
.
The os.path.dirname(path)
function returns the head of the path.
E.g.: The dirname of '/foo/bar/item'
is '/foo/bar'
.
The os.path.basename(path)
function returns the tail of the path.
E.g.: The basename of '/foo/bar/item'
returns 'item'
From: http://docs.python.org/2/library/os.path.html#os.path.basename
One can use the Jackson library as well.
Add Maven Dependency:
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-core</artifactId>
</dependency>
Simply do this:
ObjectMapper mapper = new ObjectMapper();
String json = mapper.writeValueAsString( serializableObject );
For a string variable s
:
s.Split(new string[]{Environment.NewLine},StringSplitOptions.None)
This uses your environment's definition of line endings. On Windows, line endings are CR-LF (carriage return, line feed) or in C#'s escape characters \r\n
.
This is a reliable solution, because if you recombine the lines with String.Join
, this equals your original string:
var lines = s.Split(new string[]{Environment.NewLine},StringSplitOptions.None);
var reconstituted = String.Join(Environment.NewLine,lines);
Debug.Assert(s==reconstituted);
What not to do:
StringSplitOptions.RemoveEmptyEntries
, because this will break markup such as Markdown where empty lines have syntactic purpose.new char[]{Environment.NewLine}
, because on Windows this will create one empty string element for each new line.I just went through all 4 pages of this so far, and I was rather surprised that I didn't see this way to shorten a check for InvokeRequired
:
using System;
using System.Windows.Forms;

public static void MaybeInvoke(this Control control, Action action)
{
if (control != null && control.InvokeRequired)
{
control.Invoke(action);
}
else
{
action();
}

You can run node --experimental-repl-await

Deno already has it built in.
There's no benefit to using properties with primitive types. @property
is used with heap allocated NSObjects
like NSString*
, NSNumber*
, UIButton*
, and etc, because memory managed accessors are created for free. When you create a BOOL
, the value is always allocated on the stack and does not require any special accessors to prevent memory leakage. isWorking
is simply the popular way of expressing the state of a boolean value.
In another OO language you would make a variable private bool working;
and two accessors: SetWorking
for the setter and IsWorking
for the accessor.
Crazy idea...
You could play around with some pseudo elements, and create up/down arrows of css content hex codes. The only challange will be to precise the positioning of the arrow, but it may work:

The problem with toISOString is that it gives datetime only as "Z".
ISO-8601 also defines datetime with timezone difference in hours and minutes, in the forms like 2016-07-16T19:20:30+5:30 (when timezone is ahead UTC) and 2016-07-16T19:20:30-01:00 (when timezone is behind UTC).
I don't think it is a good idea to use another plugin, moment.js for such a small task, especially when you can get it with a few lines of code.
var timezone_offset_min = new Date().getTimezoneOffset(),
offset_hrs = parseInt(Math.abs(timezone_offset_min/60)),
offset_min = Math.abs(timezone_offset_min%60),
timezone_standard;
if(offset_hrs < 10)
offset_hrs = '0' + offset_hrs;
if(offset_min > 10)
offset_min = '0' + offset_min;
// getTimezoneOffset returns an offset which is positive if the local timezone is behind UTC and vice-versa.
// So add an opposite sign to the offset
// If offset is 0, it means timezone is UTC
if(timezone_offset_min < 0)
timezone_standard = '+' + offset_hrs + ':' + offset_min;
else if(timezone_offset_min > 0)
timezone_standard = '-' + offset_hrs + ':' + offset_min;
else if(timezone_offset_min == 0)
timezone_standard = 'Z';
// Timezone difference in hours and minutes
// String such as +5:30 or -6:00 or Z
console.log(timezone_standard);
Once you have the timezone offset in hours and minutes, you can append to a datetime string.
I wrote a blog post on it : http://usefulangle.com/post/30/javascript-get-date-time-with-offset-hours-minutes

You need to set a constraint on the table to trigger a "conflict" which you then resolve by doing a replace:
CREATE TABLE data (id INTEGER PRIMARY KEY, event_id INTEGER, track_id INTEGER, value REAL);
CREATE UNIQUE INDEX data_idx ON data(event_id, track_id);
Then you can issue:
INSERT OR REPLACE INTO data VALUES (NULL, 1, 2, 3);
INSERT OR REPLACE INTO data VALUES (NULL, 2, 2, 3);
INSERT OR REPLACE INTO data VALUES (NULL, 1, 2, 5);
The "SELECT * FROM data" will give you:
2|2|2|3.0
3|1|2|5.0
Note that the data.id is "3" and not "1" because REPLACE does a DELETE and INSERT, not an UPDATE. This also means that you must ensure that you define all necessary columns or you will get unexpected NULL values.

You should be able to use join

I don't know that much JQuery but I've heard it allows to fire native events with this syntax.
$(document).ready(function(){
$('#countrylist').change(function(e){
// Your event handler
});
// And now fire change event when the DOM is ready
$('#countrylist').trigger('change');
});
You must declare the change event handler before calling trigger() or change() otherwise it won't be fired. Thanks for the mention @LenielMacaferi.

Install the additional module tablefunc
once per database, which provides the function crosstab()
. Since Postgres 9.1 you can use CREATE EXTENSION
for that:
CREATE EXTENSION IF NOT EXISTS tablefunc;
CREATE TABLE tbl (
section text
, status text
, ct integer -- "count" is a reserved word in standard SQL
);
INSERT INTO tbl VALUES
('A', 'Active', 1), ('A', 'Inactive', 2)
, ('B', 'Active', 4), ('B', 'Inactive', 5)
, ('C', 'Inactive', 7); -- ('C', 'Active') is missing
crosstab(text)
with 1 input parameter:
SELECT *
FROM crosstab(
'SELECT section, status, ct
FROM tbl
ORDER BY 1,2' -- needs to be "ORDER BY 1,2" here
) AS ct ("Section" text, "Active" int, "Inactive" int);
Returns:
Section | Active | Inactive ---------+--------+---------- A | 1 | 2 B | 4 | 5 C | 7 | -- !!
C
: the value 7
is filled in for the first column. Sometimes, this behavior is desirable, but not for this use case.crosstab(text, text)
with 2 input parameters:
SELECT *
FROM crosstab(
'SELECT section, status, ct
FROM tbl
ORDER BY 1,2' -- could also just be "ORDER BY 1" here
, $$VALUES ('Active'::text), ('Inactive')$$
) AS ct ("Section" text, "Active" int, "Inactive" int);
Returns:
Section | Active | Inactive ---------+--------+---------- A | 1 | 2 B | 4 | 5 C | | 7 -- !!
Note the correct result for C
.
The second parameter can be any query that returns one row per attribute matching the order of the column definition at the end. Often you will want to query distinct attributes from the underlying table like this:
'SELECT DISTINCT attribute FROM tbl ORDER BY 1'
That's in the manual.
Since you have to spell out all columns in a column definition list anyway (except for pre-defined crosstabN()
variants), it is typically more efficient to provide a short list in a VALUES
expression like demonstrated:
$$VALUES ('Active'::text), ('Inactive')$$)
Or (not in the manual):
$$SELECT unnest('{Active,Inactive}'::text[])$$ -- short syntax for long lists
I used dollar quoting to make quoting easier.
You can even output columns with different data types with crosstab(text, text)
- as long as the text representation of the value column is valid input for the target type. This way you might have attributes of different kind and output text
, date
, numeric
etc. for respective attributes. There is a code example at the end of the chapter crosstab(text, text)
in the manual.
db<>fiddle here
Pivot on Multiple Columns using Tablefunc - also demonstrating mentioned "extra columns"
\crosstabview
in psqlPostgres 9.6 added this meta-command to its default interactive terminal psql. You can run the query you would use as first crosstab()
parameter and feed it to \crosstabview
(immediately or in the next step). Like:
db=> SELECT section, status, ct FROM tbl \crosstabview
Similar result as above, but it's a representation feature on the client side exclusively. Input rows are treated slightly differently, hence ORDER BY
is not required. Details for \crosstabview
in the manual. There are more code examples at the bottom of that page.
Related answer on dba.SE by Daniel Vérité (the author of the psql feature):
The previously accepted answer is outdated.
The variant of the function crosstab(text, integer)
is outdated. The second integer
parameter is ignored. I quote the current manual:
crosstab(text sql, int N)
...Obsolete version of
crosstab(text)
. The parameterN
is now ignored, since the number of value columns is always determined by the calling query
Needless casting and renaming.
It fails if a row does not have all attributes. See safe variant with two input parameters above to handle missing attributes properly.
ORDER BY
is required in the one-parameter form of crosstab()
. The manual:
In practice the SQL query should always specify
ORDER BY 1,2
to ensure that the input rows are properly ordered

It depends on what you are trying to do with the XML files. If you are just trying to read the XML file (like a configuration file), The Wicked Flea is correct in suggesting SimpleXML since it creates what amounts to nested ArrayObjects. e.g. value will be accessible by $xml->root->child.
If you are looking to manipulate the XML files you're probably best off using DOM XML
realpath($_SERVER['SCRIPT_FILENAME'])
For script run under web server $_SERVER['SCRIPT_FILENAME']
will contain the full path to the initially called script, so probably your index.php. realpath()
is not required in this case.
For the script run from console $_SERVER['SCRIPT_FILENAME']
will contain relative path to your initially called script from your current working dir. So unless you changed working directory inside your script it will resolve to the absolute path.
(I'm not completely happy with the answers so far, so here is my attempt...)
I think that Kevin Wright's comment ("You can make a Promise and it's up to you to keep it. When someone else makes you a promise you must wait to see if they honour it in the Future") summarizes it pretty well, but some explanation can be useful.
Futures and promises are pretty similar concepts, the difference is that a future is a read-only container for a result that does not yet exist, while a promise can be written (normally only once). The Java 8 CompletableFuture and the Guava SettableFuture can be thought of as promises, because their value can be set ("completed"), but they also implement the Future interface, therefore there is no difference for the client.
The result of the future will be set by "someone else" - by the result of an asynchronous computation. Note how FutureTask - a classic future - must be initialized with a Callable or Runnable, there is no no-argument constructor, and both Future and FutureTask are read-only from the outside (the set methods of FutureTask are protected). The value will be set to the result of the computation from the inside.
On the other hand, the result of a promise can be set by "you" (or in fact by anybody) anytime because it has a public setter method. Both CompletableFuture and SettableFuture can be created without any task, and their value can be set at any time. You send a promise to the client code, and fulfill it later as you wish.
Note that CompletableFuture is not a "pure" promise, it can be initialized with a task just like FutureTask, and its most useful feature is the unrelated chaining of processing steps.
Also note that a promise does not have to be a subtype of future and it does not have to be the same object. In Scala a Future object is created by an asynchronous computation or by a different Promise object. In C++ the situation is similar: the promise object is used by the producer and the future object by the consumer. The advantage of this separation is that the client cannot set the value of the future.
Both Spring and EJB 3.1 have an AsyncResult class, which is similar to the Scala/C++ promises. AsyncResult does implement Future but this is not the real future: asynchronous methods in Spring/EJB return a different, read-only Future object through some background magic, and this second "real" future can be used by the client to access the result.

The problem is that there is no width set on the buttons. Try this:
.btn {width:20%;}
EDIT:
By default the buttons take an auto width of its text length plus some padding, so I guess for your example it is probably more like 14.5% for 5 buttons (to compensate for the padding).
Note:
If you don't want to try and compensate for padding you can use box-sizing:border-box;
Consider creating an index. A dictionary can do the trick. If you need the list semantics, subclass and keep the index as a private member...
In addition to above answers, another way of doing it is $_SERVER['PHP_SELF']
or simply using an empty string is to use __DIR__
.
OR
If you're on a lower PHP version (<5.3), a more common alternative is to use dirname(__FILE__)
Both returns the folder name of the file in context.
EDIT
As Boann pointed out that this returns the on-disk location of the file. WHich you would not ideally expose as a url. In that case dirname($_SERVER['PHP_SELF'])
can return the folder name of the file in context.
Made a util inspired from Dave's answer
Basically passed in a done
callback to call when the operation is finished.
// Function to timeout if a request is taking too long
const setAsyncTimeout = (cb, timeout = 0) => new Promise((resolve, reject) => {
cb(resolve);
setTimeout(() => reject('Request is taking too long to response'), timeout);
});
This is how I use it:
try {
await setAsyncTimeout(async done => {
const requestOne = await someService.post(configs);
const requestTwo = await someService.get(configs);
const requestThree = await someService.post(configs);
done();
}, 5000); // 5 seconds max for this set of operations
}
catch (err) {
console.error('[Timeout] Unable to complete the operation.', err);

I tried a couple of codes, but end up using something as simple as (in Python 3):
from datetime import datetime
df['difference_in_datetime'] = abs(df['end_datetime'] - df['start_datetime'])
If your start_datetime and end_datetime columns are in datetime64[ns]
format, datetime understands it and return the difference in days + timestamp, which is in timedelta64[ns]
format.
If you want to see only the difference in days, you can separate only the date portion of the start_datetime and end_datetime by using (also works for the time portion):
df['start_date'] = df['start_datetime'].dt.date
df['end_date'] = df['end_datetime'].dt.date
And then run:
df['difference_in_days'] = abs(df['end_date'] - df['start_date'])
Consider using Joda Time. I love this library and wish it would replace the current horrible mess that are the existing Java Date and Calendar classes. It's date handling done right.
EDIT: It's not 2009 any more, and Java 8's been out for ages. Use Java 8's built in java.time classes which are based on Joda Time, as Basil Bourque mentions above. In this case you'll want the Period class, and here's Oracle's tutorial on how to use it.

They also share a software (which is based on Opencv-1.0 and it should run under Windows platform.) that you can use (though no source code available). It will generate all the text bounding boxes (shown in color shadows) in the image. By applying to your sample images, you will get the following results:
Note: to make the result more robust, you can further merge adjacent boxes together.
Update: If your ultimate goal is to recognize the texts in the image, you can further check out gttext, which is an OCR free software and Ground Truthing tool for Color Images with Text. Source code is also available.
With this, you can get recognized texts like:
There are various ways to achieve this. Here are three.

As mentioned in Alain Beauvois's answer, and now (Q4 2013) better explained in
Copy the URL from GitHub and select in Eclipse from the menu the
File ? Import ? Git ? Projects from Git
If the Git repo isn't cloned yet:
In> order to checkout a remote project, you will have to clone its repository first.
Open the Eclipse Import wizard (e.g. File => Import
), select Git => Projects
from Git and click Next
.
Select “URI
” and click Next
.
Now you will have to enter the repository’s location and connection data. Entering the URI will automatically fill some fields. Complete any other required fields and hit Next
. If you use GitHub, you can copy the URI from the web page.
Select all branches you wish to clone and hit Next again.
Hit the Clone… button to open another wizard for cloning Git repositories.
Original answer (July 2011)
First, if your "Working Directory" is C:\Users
, that is odd, since it would mean you have cloned the GitHub repo directly within C:\Users (i.e. you have a .git
directory in C:\Users
)
Usually, you would clone a GitHub repo in "any directory of your choice\theGitHubRepoName
".
As described in the EGit user Manual page:
In any case (unless you create a "bare" Repository, but that's not discussed here), the new Repository is essentially a folder on the local hard disk which contains the "working directory" and the metadata folder.
The metadata folder is a dedicated child folder named ".git
" and often referred to as ".git-folder
". It contains the actual repository (i.e. the Commits, the References, the logs and such).The metadata folder is totally transparent to the Git client, while the working directory is used to expose the currently checked out Repository content as files for tools and editors.
Typically, if these files are to be used in Eclipse, they must be imported into the Eclipse workspace in one way or another. In order to do so, the easiest way would be to check in .project files from which the "Import Existing Projects" wizard can create the projects easily. Thus in most cases, the structure of a Repository containing Eclipse projects would look similar to something like this:
See also the Using EGit with Github section.
My working directory is now
c:\users\projectname\.git
You should have the content of that repo checked out in c:\users\projectname
(in other words, you should have more than just the .git
).
So then I try to import the project using the eclipse "import" option.
When I try to import selecting the option "Use the new projects wizard", the source code is not imported.
That is normal.
If I import selecting the option "Import as general project" the source code is imported but the created project created by Eclipse is not a java project.
Again normal.
When selecting the option "Use the new projects wizard" and creating a new java project using the wizard should'nt the code be automatically imported ?
No, that would only create an empty project.
If that project is created in c:\users\projectname
, you can then declare the eisting source directory in that project.
Since it is defined in the same working directory than the Git repo, that project should then appear as "versioned".
You could also use the "Import existing project" option, if your GitHub repo had versioned the .project
and .classpath
file, but that may not be the case here.
In the Solution Explorer window, right click the project you want to use your class library from and click the 'Add Reference' menu item. Then if the class library is in the same solution file, go to the projects tab and select it; if it's not in the same tab, you can go to the Browse tab and find it that way.
Then you can use anything in that assembly.
You can use ifconfig.
# ifconfig eth0 up
# ifconfig eth0
If the entry shows RUNNING, the interface is physically connected. This will be shown regardless if the interface is configured.
This is just another way to get the information in /sys/class/net/eth0/operstate
.
Just for the sake of it, there is of course the possibility to create Void
instance using reflection:
interface B<E>{ E method(); }
class A implements B<Void>{
public Void method(){
// do something
try {
Constructor<Void> voidConstructor = Void.class.getDeclaredConstructor();
voidConstructor.setAccessible(true);
return voidConstructor.newInstance();
} catch (Exception ex) {
// Rethrow, or return null, or whatever.
}
}
}
You probably won't do that in production.
The one with no extra imports!
Their is a pythonic standard called EAFP(Easier to Ask for Forgiveness than Permission). Below code is based on that python standard.
# The A and B dictionaries
A = {'a': 1, 'b': 2, 'c': 3}
B = {'b': 3, 'c': 4, 'd': 5}
# The final dictionary. Will contain the final outputs.
newdict = {}
# Make sure every key of A and B get into the final dictionary 'newdict'.
newdict.update(A)
newdict.update(B)
# Iterate through each key of A.
for i in A.keys():
# If same key exist on B, its values from A and B will add together and
# get included in the final dictionary 'newdict'.
try:
addition = A[i] + B[i]
newdict[i] = addition
# If current key does not exist in dictionary B, it will give a KeyError,
# catch it and continue looping.
except KeyError:
continue
EDIT: thanks to jerzyk for his improvement suggestions.
When you got:
Error: Uncaught Error: Target container is not a DOM element.
You can use DOMContentLoaded event or move your <script ...></script>
tag in the bottom of your body.
The DOMContentLoaded event fires when the initial HTML document has been completely loaded and parsed, without waiting for stylesheets, images, and subframes to finish loading.
document.addEventListener("DOMContentLoaded", function(event) {
ReactDOM.render(<App />, document.getElementById('root'));
})
Here's some custom modal code that gives the modal states more explicitly named classes:
$('.modal').on('show.bs.modal', function(e)
{
e.currentTarget.classList.add("modal-fading-in");
e.currentTarget.classList.remove("modal-fading-out");
e.currentTarget.classList.remove("modal-hidden");
e.currentTarget.classList.remove("modal-visible");
});
$('.modal').on('hide.bs.modal', function(e)
{
e.currentTarget.classList.add("modal-fading-out");
e.currentTarget.classList.remove("modal-fading-in");
e.currentTarget.classList.remove("modal-hidden");
e.currentTarget.classList.remove("modal-visible");
});
$('.modal').on('hidden.bs.modal', function(e)
{
e.currentTarget.classList.add("modal-hidden");
e.currentTarget.classList.remove("modal-fading-in");
e.currentTarget.classList.remove("modal-fading-out");
e.currentTarget.classList.remove("modal-visible");
});
$('.modal').on('shown.bs.modal', function(e)
{
e.currentTarget.classList.add("modal-visible");
e.currentTarget.classList.remove("modal-fading-in");
e.currentTarget.classList.remove("modal-fading-out");
e.currentTarget.classList.remove("modal-hidden");
});
You can then easily target the modal's various states with both JS and CSS.
JS example:
if (document.getElementById('myModal').hasClass('modal-fading-in'))
{
console.log("The modal is currently fading in. Please wait.");
}
CSS example:
.modal-fading-out, .modal-hidden
{
opacity: 0.5;
}
Here is an alternative way that doesn't override the existing certificates: [bash fragment for linux systems]
certificateFile="MyCa.cert.pem"
certificateName="MyCA Name"
for certDB in $(find ~/.mozilla* ~/.thunderbird -name "cert8.db")
do
certDir=$(dirname ${certDB});
#log "mozilla certificate" "install '${certificateName}' in ${certDir}"
certutil -A -n "${certificateName}" -t "TCu,Cuw,Tuw" -i ${certificateFile} -d ${certDir}
done
You may find certutil in the libnss3-tools package (debian/ubuntu).

As has been explained by many, object
defines a singleton instance. The one thing in the answers here that I believe is left out is that object
serves several purposes.
It can be the companion object to a class
/trait
, containing what might be considered static methods or convenience methods.
It can act much like a module, containing related/subsidiary types and definitions, etc.
It can implement an interface by extending a class
or one or more trait
s.
It can represent a case of a sealed trait
that contains no data. In this respect, it's often considered more correct than a case class
with no parameters. The special case of a sealed trait
with only case object
implementors is more or less the Scala version of an enum.
It can act as evidence for implicit
-driven logic.
It introduces a singleton type.
It's a very powerful and general construct. What can be very confusing to Scala beginners is that the same construct can have vastly different uses. And an object
can serve many of these different uses all at once, which can be even more confusing.
I know I'm coming to this late, but what the heck.
I've got almost the exact same code as Kris, using just one Activity but with 2 different layouts/views, and I want to switch between the layouts at will.
As a test, I added 2 menu options, each one switches the view:
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.item1:
setContentView(R.layout.main);
return true;
case R.id.item2:
setContentView(R.layout.alternate);
return true;
default:
return super.onOptionsItemSelected(item);
}
}
Note, I've got one Activity class. This works perfectly. So I have no idea why people are suggesting using different Activities / Intents. Maybe someone can explain why my code works and Kris's didn't.
Try using double quotes and keeping the L
in location
lowercase...
header("location: http://linkhere.com/HERE_I_WANT_THE_VARIABLE");
or for example
header("location: http://linkhere.com/$variable");
No need to concatenate here to insert variables.
In case anyone else runs into this, I took WhoIsRich's example and modified it a bit. When calling ReadReg I needed to do the following: ReadReg("App", "HKEY_CURRENT_USER\App\Version") which would then be able to read the version number from the registry, if it existed. I also am using HKCU since it does not require admin privileges to write to.
Function ReadReg(RegKey, RegPath)
Const HKEY_CURRENT_USER = &H80000001
Dim objRegistry, oReg
Set objRegistry = CreateObject("Wscript.shell")
Set oReg = GetObject("winmgmts:!root\default:StdRegProv")
if oReg.EnumKey(HKEY_CURRENT_USER, RegKey) = 0 Then
ReadReg = objRegistry.RegRead(RegPath)
else
ReadReg = ""
end if
End Function
Try this:
grep -i -A 10 "my_regex"
-A 10 means, print ten lines after match to "my_regex"
This might be a better approach than top answer if you need to compare 2 output arrays to each other but use the first array to populate the options.
This is also helpful when you have a non-numeric or offset index (key) in your array.
<select name="roles[]" multiple>
@foreach($roles as $key => $value)
<option value="{{$key}}" @if(in_array($value, $compare_roles))selected="selected"@endif>
{{$value}}
</option>
@endforeach
</select>
IF
is a PL/SQL construct. If you are executing a query, you are using SQL not PL/SQL.
In SQL, you can use a CASE
statement in the query itself
SELECT DISTINCT a.item,
(CASE WHEN b.salesman = 'VIKKIE'
THEN 'ICKY'
ELSE b.salesman
END),
NVL(a.manufacturer,'Not Set') Manufacturer
FROM inv_items a,
arv_sales b
WHERE a.co = '100'
AND a.co = b.co
AND A.ITEM_KEY = b.item_key
AND a.item LIKE 'BX%'
AND b.salesman in ('01','15')
AND trans_date BETWEEN to_date('010113','mmddrr')
and to_date('011713','mmddrr')
ORDER BY a.item
Since you aren't doing any aggregation, you don't want a GROUP BY
in your query. Are you really sure that you need the DISTINCT
? People often throw that in haphazardly or add it when they are missing a join condition rather than considering whether it is really necessary to do the extra work to identify and remove duplicates.
If you don't have access to the v$ views (as suggested by Quassnoi) there are two alternatives
select utl_inaddr.get_host_name from dual
and
select sys_context('USERENV','SERVER_HOST') from dual
Personally I'd tend towards the last as it doesn't require any grants/privileges which makes it easier from stored procedures.
I just ran into this issue. I searched for "C++" under my "Apps & Features" in Windows 10 control panel and noticed that some kind of update had just run a few days prior and installed VC++ Redistributable 2012-2017. The app that was running into the error message only required VC++ 2010. I uninstalled all of them and then reinstalled just 2010 x86/x64, and the error went away and the application functioned as expected.
Imagine you have a numpy array of text like in a messenger
>>> stex[40]
array(['Know the famous thing ...
and you want to get statistics from the corpus (text col=11) you first must get the values from dataframe (df5) and then join all records together in one single corpus:
>>> stex = (df5.ix[0:,[11]]).values
>>> a_str = ','.join(str(x) for x in stex)
>>> a_str = a_str.split()
>>> fd2 = nltk.FreqDist(a_str)
>>> fd2.most_common(50)

On the latest support library none of the solutions discussed here are necessary anymore. You can play with your Activity
's fragments as you like using the FragmentTransaction
. Just make sure that your fragments can be identified either with an id or tag.
The fragments will be restored automatically as long as you don't try to recreate them on every call to onCreate()
. Instead, you should check if savedInstanceState
is not null and find the old references to the created fragments in this case.
Here is an example:
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if (savedInstanceState == null) {
myFragment = MyFragment.newInstance();
getSupportFragmentManager()
.beginTransaction()
.add(R.id.my_container, myFragment, MY_FRAGMENT_TAG)
.commit();
} else {
myFragment = (MyFragment) getSupportFragmentManager()
.findFragmentByTag(MY_FRAGMENT_TAG);
}
...
}
Note however that there is currently a bug when restoring the hidden state of a fragment. If you are hiding fragments in your activity, you will need to restore this state manually in this case.
Eaven if you are going to prevent sql injection front-end, using html or js checks, you'd have to consider that front-end checks are "bypassable".
You can disable js or edit a pattern with a front-end development tool (built in with firefox or chrome nowadays).
So, in order to prevent SQL injection, would be right to sanitize input date backend inside your controller.
I would like to suggest to you to use filter_input() native PHP function in order to sanitize GET and INPUT values.
If you want to go ahead with security, for sensible database queries, I'd like to suggest to you to use regular expression to validate data format. preg_match() will help you in this case! But take care! Regex engine is not so light. Use it only if necessary, otherwise your application performances will decrease.
Security has a costs, but do not waste your performance!
Easy example:
if you want to double check if a value, received from GET is a number, less then 99 if(!preg_match('/[0-9]{1,2}/')){...} is heavyer of
if (isset($value) && intval($value)) <99) {...}
So, the final answer is: "No! PDO Prepared Statements does not prevent all kind of sql injection"; It does not prevent unexpected values, just unexpected concatenation
No. The most similar concept is most likely a StopIteration exception.
Adding dependencies didn't fix the issue at my end.
The issue was happening at my end because of "additional" fields that are part of the "@Entity" class and don't exist in the database.
I removed the additional fields from the @Entity class and it worked.
Visual Studio Community 2015 suffices to build extensions for Python 3.5. It's free but a 6 GB download (overkill). On my computer it installed vcvarsall at C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\vcvarsall.bat
For Python 3.4 you'd need Visual Studio 2010. I don't think there's any free edition. See https://matthew-brett.github.io/pydagogue/python_msvc.html
Try this:
$keys = array_keys($array, "Completed");
/edit As mentioned by JohnP, this method only works for non-nested arrays.
From C#3.5 I assume you're using WPF.
Just make a two-way data binding from an integer property to your text-box. WPF will show the validation error for you automatically.
For the email case, make a two-way data binding from a string property that does Regexp validation in the setter and throw an Exception upon validation error.
Look up Binding on MSDN.
The Console.CancelKeyPress event is used for this. This is how it's used:
public static void Main(string[] args)
{
Console.CancelKeyPress += delegate {
// call methods to clean up
};
while (true) {}
}
When the user presses Ctrl + C the code in the delegate is run and the program exits. This allows you to perform cleanup by calling necessairy methods. Note that no code after the delegate is executed.
There are other situations where this won't cut it. For example, if the program is currently performing important calculations that can't be immediately stopped. In that case, the correct strategy might be to tell the program to exit after the calculation is complete. The following code gives an example of how this can be implemented:
class MainClass
{
private static bool keepRunning = true;
public static void Main(string[] args)
{
Console.CancelKeyPress += delegate(object sender, ConsoleCancelEventArgs e) {
e.Cancel = true;
MainClass.keepRunning = false;
};
while (MainClass.keepRunning) {
// Do your work in here, in small chunks.
// If you literally just want to wait until ctrl-c,
// not doing anything, see the answer using set-reset events.
}
Console.WriteLine("exited gracefully");
}
}
The difference between this code and the first example is that e.Cancel
is set to true, which means the execution continues after the delegate. If run, the program waits for the user to press Ctrl + C. When that happens the keepRunning
variable changes value which causes the while loop to exit. This is a way to make the program exit gracefully.
The more efficient (less obtrusive) way of doing this is through custom formatting.
Note that this does not actually change the value of the cell. It only displays the leading zeroes in the worksheet.
In my case (admittedly very arcane and not likely to be reproduced often), this was causing the problem (this code is related to PDF generation using iTextSharp):
PdfPTable tblDuckbilledPlatypi = new PdfPTable(3);
float[] DuckbilledPlatypiRowWidths = new float[] { 42f, 76f };
tblDuckbilledPlatypi.SetWidths(DuckbilledPlatypiRowWidths);
The declaration of a 3-celled/columned table, and then setting only two vals for the width was what caused the problem, apparently. Once I changed "PdfPTable(3)" to "PdfPTable(2)" the problem went the way of the convection oven.
If you are planning to hide show some span based on click event which is initially hidden with style="display:none" then .toggle() is best option to go with.
$("span").toggle();
Reasons : Each time you don't need to check whether the style is already there or not. .toggle() will take care of that automatically and hide/show span based on current state.
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_

The accepted answers animation does not work on Safari, I've updated it using translate instead of padding-left which makes for a smoother, bulletproof animation.
Also, the accepted answers demo fiddle has a lot of unnecessary styles.

Expand your label set number of lines to 0 and also more importantly for auto layout set height to >= x. Auto layout will do the rest. You may also contain your other elements based on previous element to correctly position then.

McGarnagle has a great answer, and you'll want to be accepting his, but I thought I'd mention (since you asked) how databinding works.
It's generally implemented by firing events whenever a change is made to the data, which then causes listeners (e.g. the UI) to be updated.
Two-way binding works by doing this twice, with a bit of care taken to ensure that you don't wind up stuck in an event loop (where the update from the event causes another event to be fired).
I was gonna put this in a comment, but it was getting pretty long...
Unfortunately, re.escape()
is not suited for the replacement string:
>>> re.sub('a', re.escape('_'), 'aa')
'\\_\\_'
A solution is to put the replacement in a lambda:
>>> re.sub('a', lambda _: '_', 'aa')
'__'
because the return value of the lambda is treated by re.sub()
as a literal string.
To add to the above points. Using ArrayList
in 64bit operating system takes 2x memory than using in the 32bit operating system. Meanwhile, generic list List<T>
will use much low memory than the ArrayList
.
for example if we use a ArrayList
of 19MB in 32-bit it would take 39MB in the 64-bit. But if you have a generic list List<int>
of 8MB in 32-bit it would take only 8.1MB in 64-bit, which is a whooping 481% difference when compared to ArrayList.
Source: ArrayList’s vs. generic List for primitive types and 64-bits
Here is how I did this:
first make interface
interface NavigationInterface {
fun closeActivity()
}
next make sure activity implements interface and overrides interface method(s)
class NotesActivity : AppCompatActivity(), NavigationInterface {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_notes)
setSupportActionBar(findViewById(R.id.toolbar))
}
override fun closeActivity() {
this.finish()
}
}
then make sure to create interface listener in fragment
private lateinit var navigationInterface: NavigationInterface
override fun onCreateView(
inflater: LayoutInflater, container: ViewGroup?,
savedInstanceState: Bundle?
): View? {
//establish interface communication
activity?.let {
instantiateNavigationInterface(it)
}
// Inflate the layout for this fragment
return inflater.inflate(R.layout.fragment_notes_info, container, false)
}
private fun instantiateNavigationInterface(context: FragmentActivity) {
navigationInterface = context as NavigationInterface
}
then you can make calls like such:
view.findViewById<Button>(R.id.button_second).setOnClickListener {
navigationInterface.closeActivity()
}
<whatever onclick="doStuff();" onmouseover="in()" onmouseout="out()" />
onclick, onmouseover, onmouseout, etc. events are actually bad for performance (in Internet Explorer mainly, go figure). If you code using Visual Studio, when you run a page with these, every single one of these will create a separate SCRIPT block taking up memory, and thus slowing down performance.
Not to mention you should have a separation of concerns: JavaScript and layouts should be separated!
It is always better to create evenHandlers for any of these events, one event can capture hundreds/thousands of items, instead of creating thousands of separate script blocks for each one!
(Also, everything everyone else is saying.)
Indexes of two types can be added: when you define a primary key, MySQL will take it as index by default.
Explanation
Primary key as index
Consider you have a tbl_student
table and you want student_id
as primary key:
ALTER TABLE `tbl_student` ADD PRIMARY KEY (`student_id`)
Above statement adds a primary key, which means that indexed values must be unique and cannot be NULL.
Specify index name
ALTER TABLE `tbl_student` ADD INDEX student_index (`student_id`)
Above statement will create an ordinary index with student_index
name.
Create unique index
ALTER TABLE `tbl_student` ADD UNIQUE student_unique_index (`student_id`)
Here, student_unique_index
is the index name assigned to student_id and creates an index for which values must be unique (here null can be accepted).
Fulltext option
ALTER TABLE `tbl_student` ADD FULLTEXT student_fulltext_index (`student_id`)
Above statement will create the Fulltext index name with student_fulltext_index
, for which you need MyISAM Mysql Engine.
How to remove indexes ?
DROP INDEX `student_index` ON `tbl_student`
How to check available indexes?
SHOW INDEX FROM `tbl_student`
My mistake was that I was creating classes in resource package...
Creating classes in src/main/java solved the issue.
This is because, even though Var1
exists, you're also using an assignment statement on the name Var1
inside of the function (Var1 -= 1
at the bottom line). Naturally, this creates a variable inside the function's scope called Var1
(truthfully, a -=
or +=
will only update (reassign) an existing variable, but for reasons unknown (likely consistency in this context), Python treats it as an assignment). The Python interpreter sees this at module load time and decides (correctly so) that the global scope's Var1
should not be used inside the local scope, which leads to a problem when you try to reference the variable before it is locally assigned.
Using global variables, outside of necessity, is usually frowned upon by Python developers, because it leads to confusing and problematic code. However, if you'd like to use them to accomplish what your code is implying, you can simply add:
global Var1, Var2
inside the top of your function. This will tell Python that you don't intend to define a Var1
or Var2
variable inside the function's local scope. The Python interpreter sees this at module load time and decides (correctly so) to look up any references to the aforementioned variables in the global scope.
nonlocal
statement - check that out as well.s/\([^)]*\)//
So in Python, you'd do:
re.sub(r'\([^)]*\)', '', filename)
Unless you use the <img>
tag, which displays an image by itself, you will not be able to achieve this with pure CSS alone. You will also need TWO HTML elements as well - one for each picture. This is because the only way you can make an element display a picture via CSS is with the background-image
property, and every element can have only one background image. Which two elements you choose and how you position them is up to you. There are many ways how you can position one HTML element above another.
What to change?
set "JAVA_OPTS=%JAVA_OPTS% -Xms1024m -Xmx2048m"
Where to change? (Normally)
bin/standalone.conf(Linux) standalone.conf.bat(Windows)
What if you are using custom script which overrides the existing settings? then?
setAppServerEnvironment.cmd/.sh (kind of file name will be there)
More information are already provided by one of our committee members! BalusC.
:w
- Write a file.
!sudo
- Call shell sudo command.
tee
- The output of write (vim :w) command redirected using tee. The % is nothing but current file name i.e. /etc/apache2/conf.d/mediawiki.conf. In other words tee command is run as root and it takes standard input and write it to a file represented by %. However, this will prompt to reload file again (hit L to load changes in vim itself):
beware of the JavaScript specific definition of null. there are two definitions for "no value" in javascript. 1. Null: when a variable is null, it means it contains no data in it, but the variable is already defined in the code. like this:
var myEmptyValue = 1;
myEmptyValue = null;
if ( myEmptyValue === null ) { window.alert('it is null'); }
// alerts
in such case, the type of your variable is actually Object. test it.
window.alert(typeof myEmptyValue); // prints Object
Undefined: when a variable has not been defined before in the code, and as expected, it does not contain any value. like this:
if ( myUndefinedValue === undefined ) { window.alert('it is undefined'); }
// alerts
if such case, the type of your variable is 'undefined'.
notice that if you use the type-converting comparison operator (==), JavaScript will act equally for both of these empty-values. to distinguish between them, always use the type-strict comparison operator (===).
I think you will have to loop over the "inserted" table, which contains all rows that were updated. You can use a WHERE loop, or a WITH statement if your primary key is a GUID. This is the simpler (for me) to write, so here is my example. We use this approach, so I know for a fact it works fine.
ALTER TRIGGER [dbo].[RA2Newsletter] ON [dbo].[Reiseagent]
AFTER INSERT
AS
-- This is your primary key. I assume INT, but initialize
-- to minimum value for the type you are using.

I sure hope this helps you out. Cheers!
In Java
, the mod operation can be performed as such:
Math.floorMod(a, b)
Note:
The mod operation is different from the remainder operation. In Java
, the remainder operation can be performed as such:
a % b
You can use following code too:
foreach (var item in listBox1.Items.Cast<string>().ToList())
{
string removelistitem = "OBJECT";
if (item.Contains(removelistitem))
{
listBox1.Items.Remove(item);
}
}

After reading around alot, only this worked: In class to set Shared preferences:
SharedPreferences userDetails = getApplicationContext().getSharedPreferences("test", MODE_PRIVATE);
SharedPreferences.Editor edit = userDetails.edit();
edit.clear();
edit.putString("test1", "1");
edit.putString("test2", "2");
edit.commit();
In AlarmReciever:
SharedPreferences userDetails = context.getSharedPreferences("test", Context.MODE_PRIVATE);
String test1 = userDetails.getString("test1", "");
String test2 = userDetails.getString("test2", "");
In short, exceptions which your module or modules above are supposed to handle during runtime are called checked exceptions; others are unchecked exceptions which are either RuntimeException
or Error
.
In this video, it explains checked and unchecked exceptions in Java:
https://www.youtube.com/watch?v=ue2pOqLaArw
Try the following:
str1="2345";
int x=str1.charAt(2)-'0';
//here x=4;
if u subtract by char '0', the ASCII value needs not to be known.
plt.hist(hmag, 30, range=[6.5, 12.5], facecolor='gray', align='mid')
Ironically, I have what you want, but want something closer to what you had.
I am loading things in dynamically and asynchronously, but with an load
callback like so (using dojo and xmlhtpprequest)
dojo.xhrGet({
url: 'getCode.php',
handleAs: "javascript",
content : {
module : 'my.js'
},
load: function() {
myFunc1('blarg');
},
error: function(errorMessage) {
console.error(errorMessage);
}
});
For a more detailed explanation, see here
The problem is that somewhere along the line the code gets evaled, and if there's anything wrong with your code, the console.error(errorMessage);
statement will indicate the line where eval()
is, not the actual error. This is SUCH a big problem that I am actually trying to convert back to <script>
statements (see here.
Paste this into the console and run the commands:
## How to update R in RStudio using installr package (for Windows)
## paste this into the console and run the commands
## "The updateR() command performs the following: finding the latest R version, downloading it, running the installer, deleting the installation file, copy and updating old packages to the new R installation."
## more info here: https://cran.r-project.org/web/packages/installr/index.html
install.packages("installr")
library(installr)
updateR()
## Watch for small pop up windows. There will be many questions and they don't always pop to the front.
## Note: It warns that it might work better in Rgui but I did it in Rstudio and it worked just fine.
The right way is:
db.users.find({awards: {$elemMatch: {award:'National Medal', year:1975}}})
$elemMatch
allows you to match more than one component within the same array element.
Without $elemMatch
mongo will look for users with National Medal in some year and some award in 1975s, but not for users with National Medal in 1975.
See MongoDB $elemMatch Documentation for more info. See Read Operations Documentation for more information about querying documents with arrays.
if ( condition ) {
return;
}
The return
exits the function returning undefined
.
The exit
statement doesn't exist in javascript.
The break
statement allows you to exit a loop, not a function. For example:
var i = 0;
while ( i < 10 ) {
i++;
if ( i === 5 ) {
break;
}
}
This also works with the for
and the switch
loops.
"/tmp/test.jpg"
is not the correct path – this path starts with /
which is the root directory.
In unix, the shortcut to the current directory is .
Try this "./tmp/test.jpg"
It's a design pattern and it's not specific to c#. More about it all over the internet and SO, like on this wikipedia article.
In software engineering, the singleton pattern is a design pattern that is used to restrict instantiation of a class to one object. This is useful when exactly one object is needed to coordinate actions across the system. The concept is sometimes generalized to systems that operate more efficiently when only one object exists, or that restrict the instantiation to a certain number of objects (say, five). Some consider it an anti-pattern, judging that it is overused, introduces unnecessary limitations in situations where a sole instance of a class is not actually required, and introduces global state into an application.
You should use it if you want a class that can only be instanciated once.
Use this to limit the depth to 2:
Get-ChildItem \*\*\*,\*\*,\*
The way it works is that it returns the children at each depth 2,1 and 0.
Explanation:
This command
Get-ChildItem \*\*\*
returns all items with a depth of two subfolders. Adding \* adds an additional subfolder to search in.
In line with the OP question, to limit a recursive search using get-childitem you are required to specify all the depths that can be searched.
As many others have pointed out here, increasing the timeout settings for NGINX can solve your issue.
However, increasing your timeout settings might not be as straightforward as many of these answers suggest. I myself faced this issue and tried to change my timeout settings in the /etc/nginx/nginx.conf file, as almost everyone in these threads suggest. This did not help me a single bit; there was no apparent change in NGINX' timeout settings. Now, many hours later, I finally managed to fix this problem.
The solution lies in this forum thread, and what it says is that you should put your timeout settings in /etc/nginx/conf.d/timeout.conf (and if this file doesn't exist, you should create it). I used the same settings as suggested in the thread:
proxy_connect_timeout 600;
proxy_send_timeout 600;
proxy_read_timeout 600;
send_timeout 600;
Assuming the key is contained inside the <appSettings>
node:
ConfigurationSettings.AppSettings["theKey"];
As for "writing" - put simply, dont.
The web.config is not designed for that, if you're going to be changing a value constantly, put it in a static helper class.
The following example should demonstrate the difference:
String destroyTheWorld() {
// destroy the world logic
return "successfully destroyed the world";
}
Optional<String> opt = Optional.of("Save the world");
// we're dead
opt.orElse(destroyTheWorld());
// we're safe
opt.orElseGet(() -> destroyTheWorld());
The answer appears in the docs as well.
public T orElseGet(Supplier<? extends T> other)
:
Return the value if present, otherwise invoke other and return the result of that invocation.
The Supplier
won't be invoked if the Optional
presents. whereas,
Return the value if present, otherwise return other.
If other
is a method that returns a string, it will be invoked, but it's value won't be returned in case the Optional
exists.
The change
event not firing on deselection is the desired behaviour. You should run a selector over the entire radio group rather than just the single radio button. And your radio group should have the same name (with different values)
Consider the following code:
$('input[name="job[video_need]"]').on('change', function () {
var value;
if ($(this).val() == 'none') {
value = 'hide';
} else {
value = 'show';
}
$('#video-script-collapse').collapse(value);
});
I have same use case as yours i.e. to show an input box when a particular radio button is selected. If the event was fired on de-selection as well, I would get 2 events each time.
For brevity, we can understand these two APIs like below:
X.class.isAssignableFrom(Y.class)
If X
and Y
are the same class, or X
is Y
's super class or super interface, return true, otherwise, false.
X.class.isInstance(y)
Say y
is an instance of class Y
, if X
and Y
are the same class, or X
is Y
's super class or super interface, return true, otherwise, false.
None of that solved my problem. but what I did was if click on the pom.xml, there is a tab at the bottom named dependencies. in this tab it is split into 2 section, one called dependencies and one called dependency management. select every thing in the dependency section and click add to be under the dependency management control. close and reopen your project.
There's also concat, but it doesn't get used much
select concat('a','b') from dual;
Be careful, when you register by
LocalBroadcastManager.getInstance(this).registerReceiver()
you can't unregister by
unregisterReceiver()
you must use
LocalBroadcastManager.getInstance(this).unregisterReceiver()
or app will crash, log as follow:

pygolang provides sync.WorkGroup which, in particular, propagates exception from spawned worker threads to the main thread. For example:
#!/usr/bin/env python
"""This program demostrates how with sync.WorkGroup an exception raised in
spawned thread is propagated into main thread which spawned the worker."""
from __future__ import print_function
from golang import sync, context
def T1(ctx, *argv):
print('T1: run ... %r' % (argv,))
raise RuntimeError('T1: problem')
def T2(ctx):
print('T2: ran ok')
def main():
wg = sync.WorkGroup(context.background())
wg.go(T1, [1,2,3])
wg.go(T2)
try:
wg.wait()
except Exception as e:
print('Tmain: caught exception: %r\n' %e)
# reraising to see full traceback
raise
if __name__ == '__main__':
main()
gives the following when run:
T1: run ... ([1, 2, 3],)
T2: ran ok
Tmain: caught exception: RuntimeError('T1: problem',)
Traceback (most recent call last):
File "./x.py", line 28, in <module>
main()
File "./x.py", line 21, in main
wg.wait()
File "golang/_sync.pyx", line 198, in golang._sync.PyWorkGroup.wait

f(pywg._pyctx, *argv, **kw)
File "./x.py", line 10, in T1
raise RuntimeError('T1: problem')
RuntimeError: T1: problem
The original code from the question would be just:
wg = sync.WorkGroup(context.background())
def _(ctx):
shul.copytree(sourceFolder, destFolder)
wg.go(_)
# waits for spawned worker to complete and, on error, reraises
# its exception on the main thread.

On Servlet 3.0 or newer you could just specify
<web-app ...>
<error-page>
<location>/general-error.html</location>
</error-page>
</web-app>
But as you're still on Servlet 2.5, there's no other way than specifying every common HTTP error individually. You need to figure which HTTP errors the enduser could possibly face. On a barebones webapp with for example the usage of HTTP authentication, having a disabled directory listing, using custom servlets and code which can possibly throw unhandled exceptions or does not have all methods implemented, then you'd like to set it for HTTP errors 401, 403, 500 and 503 respectively.
<error-page>
<!-- Missing login -->
<error-code>401</error-code>
<location>/general-error.html</location>
</error-page>
<error-page>
<!-- Forbidden directory listing -->
<error-code>403</error-code>
<location>/general-error.html</location>
</error-page>
<error-page>
<!-- Missing resource -->
<error-code>404</error-code>
<location>/Error404.html</location>
</error-page>
<error-page>
<!-- Uncaught exception -->
<error-code>500</error-code>
<location>/general-error.html</location>
</error-page>
<error-page>
<!-- Unsupported servlet method -->
<error-code>503</error-code>
<location>/general-error.html</location>
</error-page>
That should cover the most common ones.
In my case, along with Mekanik's suggestions, I was receiving this error in Windows Server 2012 and I had to tick "HTTP Activation" in "Add Role Services".
if you provide a bad path or a broken link, if the compiler cannot find the image, the picture box would display an X icon on its body.
PictureBox picture = new PictureBox
{
Name = "pictureBox",
Size = new Size(100, 50),
Location = new Point(14, 17),
Image = Image.FromFile(@"c:\Images\test.jpg"),
SizeMode = PictureBoxSizeMode.CenterImage
};
p.Controls.Add(picture);
OR
PictureBox picture = new PictureBox
{
Name = "pictureBox",
Size = new Size(100, 50),
Location = new Point(14, 17),
ImageLocation = @"c:\Images\test.jpg",
SizeMode = PictureBoxSizeMode.CenterImage
};
p.Controls.Add(picture);
i'm not sure where you put images in your folder structure but you can find the path as bellow
picture.ImageLocation = Path.Combine(System.Windows.Forms.Application.StartupPath, "Resources\Images\1.jpg");

/System/Library
and /usr/bin
, as this may break your whole operating system.NOTE: The steps listed below do not affect the Apple-supplied system Python 2.7; they only remove a third-party Python framework, like those installed by python.org installers.
The complete list is documented here. Basically, all you need to do is the following:
Remove the third-party Python 2.7 framework
sudo rm -rf /Library/Frameworks/Python.framework/Versions/2.7
Remove the Python 2.7 applications directory
sudo rm -rf "/Applications/Python 2.7"
Remove the symbolic links, in /usr/local/bin
, that point to this Python version. See them using
ls -l /usr/local/bin | grep '../Library/Frameworks/Python.framework/Versions/2.7'
and then run the following command to remove all the links:
cd /usr/local/bin/
ls -l /usr/local/bin | grep '../Library/Frameworks/Python.framework/Versions/2.7' | awk '{print $9}' | tr -d @ | xargs rm
If necessary, edit your shell profile file(s) to remove adding /Library/Frameworks/Python.framework/Versions/2.7
to your PATH
environment file. Depending on which shell you use, any of the following files may have been modified:
~/.bash_login
, ~/.bash_profile
, ~/.cshrc
, ~/.profile
, ~/.tcshrc
, and/or ~/.zprofile
.
It is possible to get an SSRS report to appear on an MVC page without using iFrames or an aspx page.
The bulk of the work is explained here:
The link explains how to create a web service and MVC action method that will allow you to call the reporting service and render result of the web service as an Excel file. With a small change to the code in the example you can render it as HTML.
All you need to do then is use a button to call a javascript function that makes an AJAX call to your MVC action which returns the HTML of the report. When the AJAX call returns with the HTML just replace a div with this HTML.
We use AngularJS so my example below is in that format, but it could be any javascript function
$scope.getReport = function()
{
$http({
method: "POST",
url: "Report/ExportReport",
data:
[
{ Name: 'DateFrom', Value: $scope.dateFrom },
{ Name: 'DateTo', Value: $scope.dateTo },
{ Name: 'LocationsCSV', Value: $scope.locationCSV }
]
})
.success(function (serverData)
{
$("#ReportDiv").html(serverData);
});
};
And the Action Method - mainly taken from the above link...
[System.Web.Mvc.HttpPost]
public FileContentResult ExportReport([FromBody]List<ReportParameterModel> parameters)
{
byte[] output;
string extension, mimeType, encoding;
string reportName = "/Reports/DummyReport";
ReportService.Warning[] warnings;
string[] ids;
ReportExporter.Export(
"ReportExecutionServiceSoap"
new NetworkCredential("username", "password", "domain"),
reportName,
parameters.ToArray(),
ExportFormat.HTML4,
out output,
out extension,
out mimeType,
out encoding,
out warnings,
out ids
);
//-------------------------------------------------------------
// Set HTTP Response Header to show download dialog popup
//-------------------------------------------------------------
Response.AddHeader("content-disposition", string.Format("attachment;filename=GeneratedExcelFile{0:yyyyMMdd}.{1}", DateTime.Today, extension));
return new FileContentResult(output, mimeType);
}
So the result is that you get to pass parameters to an SSRS reporting server which returns a report which you render as HTML. Everything appears on the one page. This is the best solution I could find
That only means that an undefined column or parameter name was detected. The errror that DB2 gives should point what that may be:
DB2 SQL Error: SQLCODE=-206, SQLSTATE=42703, SQLERRMC=[THE_UNDEFINED_COLUMN_OR_PARAMETER_NAME], DRIVER=4.8.87
Double check your table definition. Maybe you just missed adding something.
I also tried google-ing this problem and saw this:

A snapshot version in Maven is one that has not been released.
The idea is that before a 1.0
release (or any other release) is done, there exists a 1.0-SNAPSHOT
. That version is what might become 1.0
. It's basically "1.0
under development". This might be close to a real 1.0
release, or pretty far (right after the 0.9
release, for example).
The difference between a "real" version and a snapshot version is that snapshots might get updates. That means that downloading 1.0-SNAPSHOT
today might give a different file than downloading it yesterday or tomorrow.
Usually, snapshot dependencies should only exist during development and no released version (i.e. no non-snapshot) should have a dependency on a snapshot version.
@Hesam 's answer is correct, CameraPreview
will work in all portrait devices, but if the device is in landscape mode or in multi-window mode, this code is working perfect, just replace onMeasure()
@Override

super.onMeasure(widthMeasureSpec, heightMeasureSpec);
int width = resolveSize(getSuggestedMinimumWidth(), widthMeasureSpec);
int height = resolveSize(getSuggestedMinimumHeight(), heightMeasureSpec);
setMeasuredDimension(width, height);
int rotation = ((Activity) mContext).getWindowManager().getDefaultDisplay().getRotation();
if ((Surface.ROTATION_0 == rotation || Surface.ROTATION_180 == rotation)) {//portrait
mPreviewSize = getOptimalPreviewSize(mSupportedPreviewSizes, height, width);
} else
mPreviewSize = getOptimalPreviewSize(mSupportedPreviewSizes, width, height);//landscape
if (mPreviewSize == null) return;
float ratio;
if (mPreviewSize.height >= mPreviewSize.width) {
ratio = (float) mPreviewSize.height / (float) mPreviewSize.width;
} else ratio = (float) mPreviewSize.width / (float) mPreviewSize.height;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N && ((Activity) mContext).isInMultiWindowMode()) {
if (getResources().getConfiguration().orientation == Configuration.ORIENTATION_PORTRAIT ||
!(Surface.ROTATION_0 == rotation || Surface.ROTATION_180 == rotation)) {
setMeasuredDimension(width, (int) (width / ratio));
} else {
setMeasuredDimension((int) (height / ratio), height);
}
} else {
if ((Surface.ROTATION_0 == rotation || Surface.ROTATION_180 == rotation)) {
Log.e("---", "onMeasure: " + height + " - " + width * ratio);

if ((width * ratio) < height)
setMeasuredDimension(width, (int) (width * ratio));

First to set group_concat_max_len

SET GLOBAL group_concat_max_len = 999999;
SELECT GROUP_CONCAT(id) FROM table_level where parent_id=4 group by parent_id;
If it was installed with plesk (not sure if it's just that, or on the phpmyadmin side: It changes the root user to admin.
The Objective-C type you should use is BOOL
. There is nothing like a native boolean datatype, therefore to be sure that the code compiles on all compilers use BOOL
. (It's defined in the Apple-Frameworks.

I'm guessing from your last question, asked 20 minutes before this one, that you are trying to parse (read and convert) the XML found through using GeoNames' FindNearestAddress.
If your XML is in a string variable called txt
and looks like this:
<address>
<street>Roble Ave</street>
<mtfcc>S1400</mtfcc>
<streetNumber>649</streetNumber>
<lat>37.45127</lat>
<lng>-122.18032</lng>
<distance>0.04</distance>
<postalcode>94025</postalcode>
<placename>Menlo Park</placename>
<adminCode2>081</adminCode2>
<adminName2>San Mateo</adminName2>
<adminCode1>CA</adminCode1>
<adminName1>California</adminName1>
<countryCode>US</countryCode>
</address>
Then you can parse the XML with Javascript DOM like this:
if (window.DOMParser)
{
parser = new DOMParser();
xmlDoc = parser.parseFromString(txt, "text/xml");
}
else // Internet Explorer
{
xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
xmlDoc.async = false;
xmlDoc.loadXML(txt);
}
And get specific values from the nodes like this:
//Gets house address number
xmlDoc.getElementsByTagName("streetNumber")[0].childNodes[0].nodeValue;
//Gets Street name
xmlDoc.getElementsByTagName("street")[0].childNodes[0].nodeValue;
//Gets Postal Code
xmlDoc.getElementsByTagName("postalcode")[0].childNodes[0].nodeValue;
In response to @gaugeinvariante's concerns about xml with Namespace prefixes. Should you have a need to parse xml with Namespace prefixes, everything should work almost identically:
NOTE: this will only work in browsers that support xml namespace prefixes such as Microsoft Edge

I just tested this and it works fine
var d = new Date(1441121836000);
The data object has a constructor which takes milliseconds as an argument.
See doco for setText() in TextView http://developer.android.com/reference/android/widget/TextView.html
To style your strings, attach android.text.style.* objects to a SpannableString, or see the Available Resource Types documentation for an example of setting formatted text in the XML resource file.
Len won't yield the total number of objects in a nested list (including multidimensional lists). If you have numpy
, use size()
. Otherwise use list comprehensions within recursion.
The answer from @Emiliano is excellent. You can also pass named parameters like so:
powershell.exe -Command 'G:\Karan\PowerShell_Scripts\START_DEV.ps1' -NamedParam1 "SomeDataA" -NamedParam2 "SomeData2"
Note the parameters are outside the command call, and you'll use:
[parameter(Mandatory=$false)]
[string]$NamedParam1,
[parameter(Mandatory=$false)]
[string]$NamedParam2
Off the top of my head, Set is used to assign COM objects to variables. By doing a Set I suspect that under the hood it's doing an AddRef() call on the object to manage it's lifetime.

For this problem Onpagechange listener is the best one But it will also have one small mistake that is it will not detect the starting time time of 0th position Once you will change the page it will starts to detect the Page selected position...For this problem I fount the easiest solution
1.You have to maintain the selected position value then use it....
2. Case 1: At the starting of the position is always Zero....
Case 2: Suppose if you set the current item means you will set that value into maintain position
3.Then do your action with the use of that maintain in your activity...
Public int maintain=0;
myViewPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {
@Override
public void onPageScrolled(int i, float v, int i2) {
//Toast.makeText(MyActivity.this, i+" Is Selected "+data.size(), Toast.LENGTH_SHORT).show();
}
@Override
public void onPageSelected( int i) {
// here you will get the position of selected page
maintain = i;
}
@Override
public void onPageScrollStateChanged(int i) {
}
});
updateButton.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(MyActivity.this, i+" Is Selected "+data.size(), Toast.LENGTH_SHORT).show();
data.set(maintain, "Replaced "+maintain);
myViewPager.getAdapter().notifyDataSetChanged();
}
});
This is the idiom I've always used to get a modified copy of a string without changing the original:
(my $newstring = $oldstring) =~ s/foo/bar/g;
In perl 5.14.0 or later, you can use the new /r
non-destructive substitution modifier:
my $newstring = $oldstring =~ s/foo/bar/gr;
NOTE:
The above solutions work without g
too. They also work with any other modifiers.

Simply using re.sub
might also work instead of str.maketrans
. And this would also work in python 2.x
>>> print(re.sub(r'(\-|\]|\^|\$|\*|\.|\\)',lambda m:{'-':'\-',']':'\]','\\':'\\\\','^':'\^','$':'\$','*':'\*','.':'\.'}[m.group()],"^stack.*/overflo\w$arr=1"))
\^stack\.\*/overflo\\w\$arr=1
I encountered a similar error. It was a noob mistake done in a hurry. Integer array without declaring size int a[] then trying to access it. C++ compiler should've caught such an error easily if it were in main. However since this particular int array was declared inside an object, it was being created at the same time as my object (many objects were being created) and the compiler was throwing a free(): invalid next size(normal) error. I thought of 2 explanations for this (please enlighten me if anyone knows more): 1.) This resulted in some random memory being assigned to it but since this wasn't accessible it was freeing up all the other heap memory just trying to find this int. 2.) The memory required by it was practically infinite for a program and to assign this it was freeing up all other memory.
A simple:
int* a;
class foo{
foo(){
for(i=0;i<n;i++)
a=new int[i];
}
Solved the problem. But it did take a lot of time trying to debug this because the compiler could not "really" find the error.
Sorry to open an old thread but I'm posting just in case it helps someone. This seems to be the easiest way to do this in Python 3.
from datetime import datetime
Date = str(datetime.now())[:10]
Hour = str(datetime.now())[11:13]
Minute = str(datetime.now())[14:16]
Second = str(datetime.now())[17:19]
Millisecond = str(datetime.now())[20:]
If you need the values as a number just cast them as an int e.g
Hour = int(str(datetime.now())[11:13])
Also think about using
$(document).ready(function() {});
Don't know why no one here came up with this yet (kinda sad). When do you execute your code??? Right at the start? Then you might want to use upper mentioned ready() function so your code is being executed after the whole page (with all it's dom elements) has been loaded and not before! Of course this is useless if you run some code that adds dom elements after page load! Then you simply want to wait for those functions and execute your code afterwards...
When you create an App, a file called styles.xml will be created in your res/values folder. If you change the styles, you can change the background, text color, etc for all your layouts. That way you don’t have to go into each individual layout and change the it manually.
styles.xml:
<resources xmlns:android="http://schemas.android.com/apk/res/android">
<style name="Theme.AppBaseTheme" parent="@android:style/Theme.Light">
<item name="android:editTextColor">#295055</item>
<item name="android:textColorPrimary">#295055</item>
<item name="android:textColorSecondary">#295055</item>
<item name="android:textColorTertiary">#295055</item>
<item name="android:textColorPrimaryInverse">#295055</item>
<item name="android:textColorSecondaryInverse">#295055</item>
<item name="android:textColorTertiaryInverse">#295055</item>
<item name="android:windowBackground">@drawable/custom_background</item>
</style>
<!-- Application theme. -->
<style name="AppTheme" parent="AppBaseTheme">
<!-- All customizations that are NOT specific to a particular API-level can go here. -->
</style>
parent="@android:style/Theme.Light"
is Google’s native colors. Here is a reference of what the native styles are:
https://android.googlesource.com/platform/frameworks/base/+/refs/heads/master/core/res/res/values/themes.xml
The default Android style is also called “Theme”. So you calling it Theme probably confused the program.
name="Theme.AppBaseTheme"
means that you are creating a style that inherits all the styles from parent="@android:style/Theme.Light"
.
This part you can ignore unless you want to inherit from AppBaseTheme again. = <style name="AppTheme" parent="AppBaseTheme">
@drawable/custom_background is a custom image I put in the drawable’s folder. It is a 300x300 png image.
#295055 is a dark blue color.
My code changes the background and text color. For Button text, please look through Google’s native stlyes (the link I gave u above).
Then in Android Manifest, remember to include the code:
<application
android:theme="@style/Theme.AppBaseTheme">
Varying is an alias for varchar, so no difference, see documentation :)
The notations varchar(n) and char(n) are aliases for character varying(n) and character(n), respectively. character without length specifier is equivalent to character(1). If character varying is used without length specifier, the type accepts strings of any size. The latter is a PostgreSQL extension.
I used part of the method from the solutions above; however, they did not work completely. On the latest version of Andy, this worked for me:
On Andy (Root Shell) [To get, right click the HandyAndy icon and select Term Shell]
Inside the shell, run these commands:
mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
cd /system/bin
cat sh > su && chmod 4775 su
Then, install SuperSU and install SU binary. This will replace the SU binary we just created. (Optional) Remove SuperSU and install Superuser by CWM. Install the su binary again. Now, root works!
edit included the newer across()
syntax
Here's another tidyverse
solution, using filter(across())
or previously filter_at
. The advantage is that you can easily extend to more than one column.
Below also a solution with filter_all
in order to find the string in any column,
using diamonds
as example, looking for the string "V"
library(tidyverse)
# for only one column... extendable to more than one creating a column list in `across` or `vars`!
mtcars %>%
rownames_to_column("type") %>%
filter(across(type, ~ !grepl('Toyota|Mazda', .))) %>%
head()
#> type mpg cyl disp hp drat wt qsec vs am gear carb
#> 1 Datsun 710 22.8 4 108.0 93 3.85 2.320 18.61 1 1 4 1
#> 2 Hornet 4 Drive 21.4 6 258.0 110 3.08 3.215 19.44 1 0 3 1
#> 3 Hornet Sportabout 18.7 8 360.0 175 3.15 3.440 17.02 0 0 3 2
#> 4 Valiant 18.1 6 225.0 105 2.76 3.460 20.22 1 0 3 1
#> 5 Duster 360 14.3 8 360.0 245 3.21 3.570 15.84 0 0 3 4
#> 6 Merc 240D 24.4 4 146.7 62 3.69 3.190 20.00 1 0 4 2
The now superseded syntax for the same would be:
mtcars %>%
rownames_to_column("type") %>%
filter_at(.vars= vars(type), all_vars(!grepl('Toyota|Mazda',.)))
# remove all rows where any column contains 'V'
diamonds %>%
filter(across(everything(), ~ !grepl('V', .))) %>%
head
#> # A tibble: 6 x 10

#> <dbl> <ord> <ord> <ord> <dbl> <dbl> <int> <dbl> <dbl> <dbl>

#> 6 0.31 Ideal J SI2 62.2 54 344 4.35 4.37 2.71
The now superseded syntax for the same would be:
diamonds %>%
filter_all(all_vars(!grepl('V', .))) %>%
head
I tried to find an across alternative for the following, but I didn't immediately come up with a good solution:
#get all rows where any column contains 'V'
diamonds %>%
filter_all(any_vars(grepl('V',.))) %>%
head
#> # A tibble: 6 x 10
#> carat cut color clarity depth table price x y z
#> <dbl> <ord> <ord> <ord> <dbl> <dbl> <int> <dbl> <dbl> <dbl>

#> 6 0.22 Fair E VS2 65.1 61 337 3.87 3.78 2.49
Update: Thanks to user Petr Kajzar in this answer, here also an approach for the above:
diamonds %>%
filter(rowSums(across(everything(), ~grepl("V", .x))) > 0)
I have a slightly different way of doing this than the accepted answer. This way you can avoid using GROUP_CONCAT which has a limit of 1024 characters and will not work if you have a lot of fields.
SET @sql = '';
SELECT
@sql := CONCAT(@sql,if(@sql='','',', '),temp.output)
FROM
(
SELECT
DISTINCT
CONCAT(
'MAX(IF(pa.fieldname = ''',
fieldname,
''', pa.fieldvalue, NULL)) AS ',
fieldname
) as output
FROM
product_additional
) as temp;
SET @sql = CONCAT('SELECT p.id
, p.name
, p.description, ', @sql, '
FROM product p
LEFT JOIN product_additional AS pa
ON p.id = pa.id
GROUP BY p.id');
PREPARE stmt FROM @sql;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;
First you need to set your device to debugging mode. On Android 4.X that means as described in another answer in another question:
Open up your device’s “Settings”. This can be done by pressing the Menu button while on your home screen and tapping “System settings”
Now scroll to the bottom and tap “About phone” or “About tablet”.
At the “About” screen, scroll to the bottom and tap on “Build number” seven times. [Note this is no joke]
Make sure you tap seven times. If you see a “Not need, you are already a developer!” message pop up, then you know you have done it correctly.
Done! By tapping on “Build number” seven times, you have unlocked USB debugging mode on Android 4.2 and higher. You can now enable/disable it whenever you desire by going to “Settings” -> “Developer Options” -> “Debugging” ->” USB debugging”.
The next step is to connect your device to your computer via the USB cable.
The next step is to install a USB driver for it. On the official website you find a list with sources for drivers for phones from various different companies.
Eclipse now should give you the phone as a choice when you click on Run and it presents you possible device to launch.
In some case Eclpise will tell you Target Unknown which prevents you from using the device. If that's the case you might have to restart the phone. You might also have to check and recheckUSB debugging, till the phone asks you to allow your particular computer to do usb debugging.
I had the same error message and my way to deal with it is as follows:
var Hello = React.createClass({
render: function() {
return (
<div className="divClass">
<img src={this.props.url} alt={`${this.props.title}'s picture`} className="img-responsive" />
<span>Hello {this.props.name}</span>
</div>
);
}
});
I had this error on AWS Lightsail, used the top answer above
from
listen [::]:80;
to
listen [::]:80 ipv6only=on default_server;
and then click on "reboot" button inside my AWS account, I have main server Apache and Nginx as proxy.
(Similar to Azder's answer, but a slightly different tact.)
I don't believe there is a predefined protocol handler for content from the classpath. (The so-called classpath:
protocol).
However, Java does allow you to add your own protocols. This is done through providing concrete implementations java.net.URLStreamHandler
and java.net.URLConnection
.
This article describes how a custom stream handler can be implemented: http://java.sun.com/developer/onlineTraining/protocolhandlers/.
According to protocol documentation there are at least three options website designers can use to inform sitemap.xml location to search engines:
So, unless they have chosen to publish the sitemap location on their robots.txt file, you cannot really know where they have put their sitemap.xml files.
On Oracle XE this works:
SELECT 'DROP TABLE "' || TABLE_NAME || '";'
FROM USER_TABLES
WHERE TABLE_NAME LIKE 'YOURTABLEPREFIX%'
Or if you want to remove the constraints and free up space as well, use this:
SELECT 'DROP TABLE "' || TABLE_NAME || '" cascade constraints PURGE;'
FROM USER_TABLES
WHERE TABLE_NAME LIKE 'YOURTABLEPREFIX%'
Which will generate a bunch of DROP TABLE cascade constraints PURGE
statements...
For VIEWS
use this:
SELECT 'DROP VIEW "' || VIEW_NAME || '";'
FROM USER_VIEWS
WHERE VIEW_NAME LIKE 'YOURVIEWPREFIX%'
If you have several divs to hide, you could use an setInterval
and a number of cycles to do like in:
<div id="div1">1</div><div id="div2">2</div>
<div id="div3">3</div><div id="div4">4</div>
<script>
function hideDiv(elm){
var interval,
unit = 1000,
cycle = 5,
hide = function(){
interval = setInterval(function(){
if(--cycle === 0){
elm.style.display = 'none';
clearInterval(interval);
}
elm.setAttribute('data-cycle', cycle);
elm.innerHTML += '*';
}, unit);
};
elm.onmouseover = function(){
clearInterval(interval);
};
elm.onmouseout = function(){
hide();
};
hide();
}
function hideDivs(ids){
var id;
while(id = ids.pop()){
hideDiv(document.getElementById(id));
}
}
hideDivs(['div1','div2','div3','div4']);
</script>
A jar file is a zip archive. You can extract it using 7zip (a great simple tool to open archives). You can also change its extension to zip and use whatever to unzip the file.
Now you have your class file. There is no easy way to edit class file, because class files are binaries (you won't find source code in there. maybe some strings, but not java code). To edit your class file you can use a tool like classeditor.
You have all the strings your class is using hard-coded in the class file. So if the only thing you would like to change is some strings you can do it without using classeditor.
Your code already contains a beautiful way to execute all statements from a specified sql file
# Open and read the file as a single buffer
fd = open('ZooDatabase.sql', 'r')
sqlFile = fd.read()
fd.close()
# all SQL commands (split on ';')
sqlCommands = sqlFile.split(';')
# Execute every command from the input file
for command in sqlCommands:
# This will skip and report errors
# For example, if the tables do not yet exist, this will skip over
# the DROP TABLE commands
try:
c.execute(command)
except OperationalError, msg:
print "Command skipped: ", msg
Wrap this in a function and you can reuse it.
def executeScriptsFromFile(filename):
# Open and read the file as a single buffer
fd = open(filename, 'r')
sqlFile = fd.read()
fd.close()
# all SQL commands (split on ';')
sqlCommands = sqlFile.split(';')
# Execute every command from the input file
for command in sqlCommands:
# This will skip and report errors
# For example, if the tables do not yet exist, this will skip over
# the DROP TABLE commands
try:
c.execute(command)
except OperationalError, msg:
print "Command skipped: ", msg
To use it
executeScriptsFromFile('zookeeper.sql')
You said you were confused by
result = c.execute("SELECT * FROM %s;" % table);
In Python, you can add stuff to a string by using something called string formatting.
You have a string "Some string with %s"
with %s, that's a placeholder for something else. To replace the placeholder, you add % ("what you want to replace it with") after your string
ex:
a = "Hi, my name is %s and I have a %s hat" % ("Azeirah", "cool")
print(a)
>>> Hi, my name is Azeirah and I have a Cool hat
Bit of a childish example, but it should be clear.
Now, what
result = c.execute("SELECT * FROM %s;" % table);
means, is it replaces %s with the value of the table variable.
(created in)
for table in ['ZooKeeper', 'Animal', 'Handles']:
# for loop example
for fruit in ["apple", "pear", "orange"]:
print fruit
>>> apple
>>> pear
>>> orange

If you need to store just simple values like API token or login data (not passwords!), here is what I used:
import 'package:shared_preferences/shared_preferences.dart';
asyncFunc() async { // Async func to handle Futures easier; or use Future.then
SharedPreferences prefs = await SharedPreferences.getInstance();
}
...
// Set
prefs.setString('apiToken', token);
// Get
String token = prefs.getString('apiToken');
// Remove
prefs.remove('apiToken');
Don't forget to add shared_preferences
dependency in your pubspec.yaml (preserve spacing format):
dependencies:
shared_preferences: any
Checking the Internet connection availability in (iOS) Xcode 8.2 , Swift 3.0
This is simple method for checking the network availability. I managed to translate it to Swift 2.0 and here the final code. The existing Apple Reachability class and other third party libraries seemed to be too complicated to translate to Swift.
This works for both 3G and WiFi connections.
Don’t forget to add “SystemConfiguration.framework” to your project builder.
//Create new swift class file Reachability in your project.
import SystemConfiguration
public class Reachability {
class func isConnectedToNetwork() -> Bool {
var zeroAddress = sockaddr_in()
zeroAddress.sin_len = UInt8(MemoryLayout.size(ofValue: zeroAddress))
zeroAddress.sin_family = sa_family_t(AF_INET)
let defaultRouteReachability = withUnsafePointer(to: &zeroAddress) {
$0.withMemoryRebound(to: sockaddr.self, capacity: 1) {zeroSockAddress in
SCNetworkReachabilityCreateWithAddress(nil, zeroSockAddress)
}
}
var flags = SCNetworkReachabilityFlags()
if !SCNetworkReachabilityGetFlags(defaultRouteReachability! , &flags) {
return false
}
let isReachable = (flags.rawValue & UInt32(kSCNetworkFlagsReachable)) != 0
let needsConnection = (flags.rawValue & UInt32(kSCNetworkFlagsConnectionRequired)) != 0
return (isReachable && !needsConnection)
}
}
// Check network connectivity from anywhere in project by using this code.
if Reachability.isConnectedToNetwork() == true {
print("Internet connection OK")
} else {
print("Internet connection FAILED")

Styling the infowindow is fairly straightforward with vanilla javascript. I used some of the info from this thread when writing this. I also took into account the possible problems with earlier versions of ie (although I have not tested it with them).
var infowindow = new google.maps.InfoWindow({
content: '<div id="gm_content">'+contentString+'</div>'
});
google.maps.event.addListener(infowindow,'domready',function(){
var el = document.getElementById('gm_content').parentNode.parentNode.parentNode;
el.firstChild.setAttribute('class','closeInfoWindow');
el.firstChild.setAttribute('title','Close Info Window');
el = (el.previousElementSibling)?el.previousElementSibling:el.previousSibling;
el.setAttribute('class','infoWindowContainer');
for(var i=0; i<11; i++){
el = (el.previousElementSibling)?el.previousElementSibling:el.previousSibling;
el.style.display = 'none';
}
});
The code creates the infowindow as usual (no need for plugins, custom overlays or huge code), using a div with an id to hold the content. This gives a hook in the system that we can use to get the correct elements to manipulate with a simple external stylesheet.
There are a couple of extra pieces (that are not strictly needed) which handle things like giving a hook into the div with the close info window image in it.
The final loop hides all the pieces of the pointer arrow. I needed this myself as I wanted to have transparency on the infowindow and the arrow got in the way. Of course, with the hook, changing the code to replace the arrow image with a png of your choice should be fairly simple too.
If you want to change it to jquery (no idea why you would) then that should be fairly simple.
I'm not usually a javascript developer so any thoughts, comments, criticisms welcome :)

u can't get it's md5 without read full content. but u can use update function to read the files content block by block.
m.update(a); m.update(b) is equivalent to m.update(a+b)
To serve all requests from a Spring app as well as /favicon.ico and the JSP files from /WEB-INF/jsp/* that Spring's AbstractUrlBasedView will request you can just remap the jsp servlet and default servlet:
<servlet>
<servlet-name>springapp</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>jsp</servlet-name>
<url-pattern>/WEB-INF/jsp/*</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>default</servlet-name>
<url-pattern>/favicon.ico</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>springapp</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
We can't rely on the *.jsp url-pattern on the standard mapping for the jsp servlet because the path pattern '/*' is matched before any extension mapping is checked. Mapping the jsp servlet to a deeper folder means it's matched first. Matching '/favicon.ico' exactly happens before path pattern matching. Deeper path matches will work, or exact matches, but no extension matches can make it past the '/*' path match. Mapping '/' to default servlet doesn't appear to work. You'd think the exact '/' would beat the '/*' path pattern on springapp.
The above filter solution doesn't work for forwarded/included JSP requests from the application. To make it work I had to apply the filter to springapp directly, at which point the url-pattern matching was useless as all requests that go to the application also go to its filters. So I added pattern matching to the filter and then learned about the 'jsp' servlet and saw that it doesn't remove the path prefix like the default servlet does. That solved my problem, which was not exactly the same but common enough.
I suggest much better solution. Task in my case: add http://google.com/ path before each record and import multiple fields.
CSV single field value (all images just have filenames, separate by |):
"123.jpg|345.jpg|567.jpg"
Tamper 1st plugin: find and replace by REGEXP: pattern: /([a-zA-Z0-9]*)./ replacement: http://google.com/$1
Tamper 2nd plugin: explode setting: explode by |
In this case you don't need any additinal fields mappings and can use 1 field in CSV
JonSkeet has a good answer but as an alternative if you wanted to keep the result more portable you could convert the date into an ISO 8601 format which could then be read into most other frameworks but this may fall outside your requirements.
value.ToUniversalTime().ToString("O");
you can use following these component to float right
alignItems aligns children in the cross direction. For example, if children are flowing vertically, alignItems controls how they align horizontally.
alignItems: 'flex-end'
justifyContent aligns children in the main direction. For example, if children are flowing vertically, justifyContent controls how they align vertically.
justifyContent: 'flex-end'
alignSelf controls how a child aligns in the cross direction,
alignSelf : 'flex-end'
Imho this is a flaw in many c compilers. I know for a fact that the compilers i worked with do not store a "static const"variable at an adress but replace the use in the code by the very constant. This can be verified as you will get the same checksum for the produced code when you use a preprocessors #define directive and when you use a static const variable.
Either way you should use static const variables instead of #defines whenever possible as the static const is type safe.
Here's what worked for me:
select visits, activations, simulations, simulations/activations
as sims_per_visit, activations/visits*100
as adoption_rate, simulations/activations*100
as completion_rate, duration/60
as minutes, m1 as month, Wk1 as week, Yr1 as year
from
(
(select count(*) as visits, year(stamp) as Yr1, week(stamp) as Wk1, month(stamp)
as m1 from sessions group by week(stamp), year(stamp)) as t3
join
(select count(*) as activations, year(stamp) as Yr2, week(stamp) as Wk2,
month(stamp) as m2 from sessions where activated='1' group by week(stamp),
year(stamp)) as t4
join
(select count(*) as simulations, year(stamp) as Yr3 , week(stamp) as Wk3,
month(stamp) as m3 from sessions where simulations>'0' group by week(stamp),
year(stamp)) as t5
join
(select avg(duration) as duration, year(stamp) as Yr4 , week(stamp) as Wk4,
month(stamp) as m4 from sessions where activated='1' group by week(stamp),
year(stamp)) as t6
)
where Yr1=Yr2 and Wk1=Wk2 and Wk1=Wk3 and Yr1=Yr3 and Yr1=Yr4 and Wk1=Wk4
I used joins, not unions (I needed different columns for each query, a join puts it all in the same column) and I dropped the quotation marks (compared to what Liam was doing) because they were giving me errors.
Thanks! I couldn't have pulled that off without this page! PS: Sorry I don't know how you're getting your statements formatted with colors. etc.
Since this is a path I'd probably use array and join:
source = [ROOT_DIR, project, 'App.config'] * '/'
