xml was not in the WEB-INF folder, thats why i was getting this error, make sure that web.xml and xxx-servlet.xml is inside WEB_INF folder and not in the webapp folder .
In MinGW, I had to install the following things:
Basic Setup -> mingw32-base
Basic Setup -> mingw32-gcc-g++
Basic Setup -> msys-base
And in Eclipse, go to
Windows -> Preferences -> C/C++ -> Build -> Environment
And set the following environment variables (with "Append variables to native environment" option set):
MINGW_HOME C:\MinGW
PATH C:\MinGW\bin;C:\MinGW\msys\1.0\bin
Click "Apply" and then "OK".
This worked for me, as far as I can tell.
I had a similar issue but in my case, the solution was to dispatch the action as an async task in the main queue
DispatchQueue.main.async {
let vc = self.storyboard?.instantiateViewController(withIdentifier: myVCID) as! myVCName
self.present(vc, animated: true, completion: nil)
}
You may be better off working out what value type your function or code accepts, and asking for that:
if (is.integer(aVariable))
{
do whatever
}
This may be an improvement over isnull, because it provides type checking. On the other hand, it may reduce the genericity of your code.
Alternatively, just make the function you want:
is.defined = function(x)!is.null(x)
Wow. I'm unsure why this was so hard. I found I was unable to use any of the code samples above because I was using log4j2 over slf4j. This is my solution:
public class SpecialLogServiceTest {
@Mock
private Appender appender;
@Captor
private ArgumentCaptor<LogEvent> captor;
@InjectMocks
private SpecialLogService specialLogService;
private LoggerConfig loggerConfig;
@Before
public void setUp() {
// prepare the appender so Log4j likes it
when(appender.getName()).thenReturn("MockAppender");
when(appender.isStarted()).thenReturn(true);
when(appender.isStopped()).thenReturn(false);
final LoggerContext ctx = (LoggerContext) LogManager.getContext(false);
final Configuration config = ctx.getConfiguration();
loggerConfig = config.getLoggerConfig("org.example.SpecialLogService");
loggerConfig.addAppender(appender, AuditLogCRUDService.LEVEL_AUDIT, null);
}
@After
public void tearDown() {
loggerConfig.removeAppender("MockAppender");
}
@Test
public void writeLog_shouldCreateCorrectLogMessage() throws Exception {
SpecialLog specialLog = new SpecialLogBuilder().build();
String expectedLog = "this is my log message";
specialLogService.writeLog(specialLog);
verify(appender).append(captor.capture());
assertThat(captor.getAllValues().size(), is(1));
assertThat(captor.getAllValues().get(0).getMessage().toString(), is(expectedLog));
}
}
matrix multiplication, see the following example:
> A <- matrix (c(1,3,4, 5,8,9, 1,3,3), 3,3)
> A
[,1] [,2] [,3]
[1,] 1 5 1
[2,] 3 8 3
[3,] 4 9 3
>
> B <- matrix (c(2,4,5, 8,9,2, 3,4,5), 3,3)
>
> B
[,1] [,2] [,3]
[1,] 2 8 3
[2,] 4 9 4
[3,] 5 2 5
>
>
> A %*% B
[,1] [,2] [,3]
[1,] 27 55 28
[2,] 53 102 56
[3,] 59 119 63
> B %*% A
[,1] [,2] [,3]
[1,] 38 101 35
[2,] 47 128 43
[3,] 31 86 26
Also see:
http://en.wikipedia.org/wiki/Matrix_multiplication
If this does not follow the size of matrix rule you will get the error:

Error in A %*% B : non-conformable arguments
Simply & Easy : JavaScript code :
function JoinedOrNot(){
var cat = document.getElementById("mySelect");
if(cat.value == "yes"){
document.getElementById("mySelect1").disabled = false;
}else{
document.getElementById("mySelect1").disabled = true;
}
}
just add in this line [onChange="JoinedOrNot()"] : <select id="mySelect" onchange="JoinedOrNot()">
it's work fine ;)
Type "ctor" and press the TAB key twice this will add the default constructor automatically

The border is actually a shadow. So to hide it I had to do this:
input[type="text"]:focus{
box-shadow: 0 0 0 rgb(255, 255, 255);
}
input[type="checkbox"]:focus{
box-shadow: 0 0 0 rgb(255, 255, 255);
}

Here is a Live Example About it
I was solving this algorithm and get stuck with the pairs part.
This explanation help me a lot https://betterexplained.com/articles/techniques-for-adding-the-numbers-1-to-100/
So to calculate the sum of series of numbers:
n(n+1)/2
But you need to calculate this
1 + 2 + ... + (n-1)
So in order to get this you can use
n(n+1)/2 - n
that is equal to
n(n-1)/2
ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
then add elements for each pair
nameValuePairs.add(new BasicNameValuePair("yourReqVar", Value);
nameValuePairs.add( ..... );
Then use the HttpPost:
HttpPost httppost = new HttpPost(URL);
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
and use the HttpClient
and Response
to get the response from the server
If you want to have an affix on your header you can use this tricks, add position: relative on your th and change the position in eventListener('scroll')
I have created an example: https://codesandbox.io/s/rl1jjx0o
I use vue.js but you can use this, without vue.js
@import url("http://netdna.bootstrapcdn.com/bootstrap/3.0.0-wip/css/bootstrap.min.css");
.row {
height: 100px;
background-color: green;
}
.container {
margin-top: 50px;
box-shadow: 0 0 30px black;
padding:0 15px 0 15px;
}
<div class="container">
<div class="row">one</div>

Given
d = [[180.0], [173.8], [164.2], [156.5], [147.2], [138.2]]
and your specific question: How can I remove the brackets?
Using list comprehension :
new_d = [i[0] for i in d]
will give you this
[180.0, 173.8, 164.2, 156.5, 147.2, 138.2]
then you can access individual items with the appropriate index, e.g., new_d[0]
will give you 180.0
etc which you can then use for math.
If you are going to have a collection of data, you will have some sort of bracket or parenthesis.
Note, this solution is aimed specifically at your question/problem, it doesn't provide a generalized solution. I.e., it will work for your case.
This will help you to change the name for "no file choose to Select profile picture"
<input type='file'id="files" class="hidden"/>
<label for="files">Select profile picture</label>
If you need to add multiple then you can do it like this:
$('#element').css({
'margin-left': '5px',
'margin-bottom': '-4px',
//... and so on
});
As a good practice I would also put the property name between quotes to allow the dash since most styles have a dash in them. If it was 'display', then quotes are optional but if you have a dash, it will not work without the quotes. Anyways, to make it simple: always enclose them in quotes.
It's a little hard to google when all you have are symbols ;) The terms to use are "JavaScript conditional operator".
If you see any more funny symbols in JavaScript, you should try looking up JavaScript's operators first: Mozilla Developer Center's list of operators. The one exception you're likely to encounter is the $
symbol.
To answer your question, conditional operators replace simple if statements. An example is best:
var insurancePremium = age > 21 ? 100 : 200;
Instead of:
var insurancePremium;
if (age > 21) {
insurancePremium = 100;
} else {
insurancePremium = 200;
}
I use this to override system's DNS with localserver
in about:config
change this value:
network.dns.forceResolve
network.dns.ipv4OnlyDomains
network.dns.localDomains
with IP address of local DNS server (for exsample 192.168.1.88)

If you want vertical spacing between elements, use a margin.
Don't add extra elements if you don't need to.
You can use objective c Runtime feature for associating imagename with the UImageView.
First import #import <objc/runtime.h>
in your class
then implement your code as below :
NSString *filename = @"exampleImage";
UIImage *image = [UIImage imagedName:filename];
objc_setAssociatedObject(image, "imageFilename", filename, OBJC_ASSOCIATION_COPY);
UIImageView *imageView = [[UIImageView alloc] initWithImage:image];
//You can then get the image later:
NSString *filename = objc_getAssociatedObject(imageView, "imageFilename");
Hope it helps you.
You can use SSMS's "Generate Scripts..." function to script out whatever you need to transfer. Right-click on the source database in SSMS, choose "Generate Scripts...", and follow the wizard along. Then run your resultant script that will now contain the stored procedure create statements.
Multiple SQL statements must be executed with the mysqli_multi_query()
function.
Example (MySQLi Object-oriented):
<?php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = "INSERT INTO names (firstname, lastname)
VALUES ('inpute value here', 'inpute value here');";
$sql .= "INSERT INTO phones (landphone, mobile)
VALUES ('inpute value here', 'inpute value here');";
if ($conn->multi_query($sql) === TRUE) {
echo "New records created successfully";
} else {
echo "Error: " . $sql . "<br>" . $conn->error;
}
$conn->close();
?>
command+fn+F12 is correct. Lacking of button fn the F12 is used adjust the volume.
$('.btnMedio').click(function(event) {
// Preventing default action of the event
event.preventDefault();
// Getting the height of the document
var n = $(document).height();
$('html, body').animate({ scrollTop: n }, 50);
// | |
// | --- duration (milliseconds)
// ---- distance from the top
});
I prefer this solution, over the accepted answer by Michael Williamson, it catches changes to sources+inline files, then sources+headers, and finally sources only. Advantage here is that the whole library is not recompiled if only a a few changes are made. Not a huge consideration for a project with a couple of files, bur if you have 10 or a 100 sources, you will notice the difference.

The answer to this depends very much on how your specific Java compiler optimizes the bytecode it generates. Strings are immutable and, theoretically, each "+" operation can create a new one. But, your compiler almost certainly optimizes away interim steps in building long strings. It's entirely possible that both lines of code above generate the exact same bytecode.
The only real way to know is to test the code iteratively in your current environment. Write a QD app that concatenates strings both ways iteratively and see how they time out against each other.
You can try this way:
$datetime = new DateTime('2010-12-30 23:21:46');
echo $datetime->format(DATE_ATOM);
If you want to replace any node value you can do like this
JSONObject json = new JSONObject(str);
String xml = XML.toString(json);
xml.replace("old value", "new value");

The so-called "Rosetta Flash" vulnerability is that allowing arbitrary yet identifier-like text at the beginning of a JSONP response is sufficient for it to be interpreted as a Flash file executing in that origin. See for more information: http://miki.it/blog/2014/7/8/abusing-jsonp-with-rosetta-flash/
JSONP responses from the proxy servlet now: * are prefixed with "/**/", which still allows them to execute as JSONP but removes requester control over the first bytes of the response. * have the response header Content-Disposition: attachment.
If your string is going in a UIView (e.g a UILabel), you also need to set the number of lines to 0
myView.numberOfLines=0;
You may be looking for the special HTML character,
.
You can use this to get a line break, and it can be inserted immediately following the last character in the current line. One place this is especially useful is if you want to include multiple lines in a list within a title or alt
label.
There are VBA methods to zip and unzip using the windows built in compression as well, which should give some insight as to how the system operates. You may be able to build these methods into a scripting language of your choice.
The basic principle is that within windows you can treat a zip file as a directory, and copy into and out of it. So to create a new zip file, you simply make a file with the extension .zip
that has the right header for an empty zip file. Then you close it, and tell windows you want to copy files into it as though it were another directory.
Unzipping is easier - just treat it as a directory.

I try to perform a TLS1.2 connection. I tried eveything mention above but didn't work. Do you have any additional idea?
String WebserviceApiURL = "https://soapServiceURL";
Uri uri = new Uri(WebserviceApiURL);
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(uri);
request.Method = "GET";
request.ContentType = "application/json";
request.Headers.Add("Token", "xxxxxx");
System.Net.ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls12;
System.Net.ServicePointManager.Expect100Continue = false;
request.KeepAlive = false;
request.ProtocolVersion = HttpVersion.Version10;
request.ServicePoint.ConnectionLimit = 1;
WebResponse response = request.GetResponse();
Like others suggested you are better off using collection. If you however for some reason must stick to array then Apache Commons ArrayUtils may help:
int[] series = {4,2};
series = ArrayUtils.add(series, 3); // series is now {4,2,3}
series = ArrayUtils.add(series, 4); // series is now {4,2,3,4};
Note that the add
method creates a new array, copies the given array and appends the new element at the end, which may have impact on performance.
Do you have a local user.name
or user.email
that's overriding the global one?
git config --list --global | grep user
user.name=YOUR NAME
user.email=YOUR@EMAIL
git config --list --local | grep user
user.name=YOUR NAME
user.email=
If so, remove them
git config --unset --local user.name
git config --unset --local user.email
The local settings are per-clone, so you'll have to unset the local user.name
and user.email
for each of the repos on your machine.
Use vbCrLf
or vbNewLine
. It works with MessageBoxes and many other controls I tested.
Dim str As String
str = "First line" & vbCrLf & "Second line"
MsgBox(str)
str = "First line" & vbNewLine & "Second line"
MsgBox(str)
It will show two identical MessageBoxes with 2 lines.
One more way of running an R script from the command line would be:
R < scriptName.R --no-save
or with --save
.
See also What's the best way to use R scripts on the command line (terminal)?.
For my future self who comes here via Google:
train_test_split
is now in model_selection
, hence:
from sklearn.model_selection import train_test_split
# given:
# features: xs
# ground truth: ys
x_train, x_test, y_train, y_test = train_test_split(xs, ys,
test_size=0.33,
random_state=0,
stratify=ys)
is the way to use it. Setting the random_state
is desirable for reproducibility.
Most form inputs are always set, even if not filled up, so you must check for the emptiness too.
Since !empty()
is already checks for both, you can use this:
if (!empty($_POST["mail"])) {
echo "Yes, mail is set";
} else {
echo "No, mail is not set";
}
The fastest way should be:
<%@ page import="java.util.Map" %>
Map<String, String[]> parameters = request.getParameterMap();
for (Map.Entry<String, String[]> entry : parameters.entrySet()) {
if (entry.getKey().startsWith("question")) {
String[] values = entry.getValue();
// etc.
Note that you can't do:
for (Map.Entry<String, String[]> entry :
request.getParameterMap().entrySet()) { // WRONG!
for reasons explained here.
why do these two different operators, [ ]
, and [[ ]]
, return the same result?
x = list(1, 2, 3, 4)
[ ]
provides sub setting operation. In general sub set of any object
will have the same type as the original object. Therefore, x[1]
provides a list. Similarly x[1:2]
is a subset of original list,
therefore it is a list. Ex.
x[1:2]
[[1]] [1] 1
[[2]] [1] 2
[[ ]]
is for extracting an element from the list. x[[1]]
is valid
and extract the first element from the list. x[[1:2]]
is not valid as [[ ]]
does not provide sub setting like [ ]
.
x[[2]] [1] 2
> x[[2:3]] Error in x[[2:3]] : subscript out of bounds
foreach (DataRow dr in dtSpecificOrders.rows)
{
dtSpecificOrders.Rows.Add(dr.ItemArray);
}
Readonly will not "grayout" the textbox and will still submit the value on a postback.
You should be able to use the IF function for that. the syntax is =IF(condition, value_if_true, value_if_false)
. To add an extra column with only the non-reimbursed amounts, you would use something like:
=IF(B1="No", A1, 0)
and sum that. There's probably a way to include it in a single cell below the column as well, but off the top of my head I can't think of anything simple.
namespace ReverseString
{
class Program
{
static void Main(string[] args)
{
string stat = "This is an example of code" +
"This code has written in C#\n\n";
Console.Write(stat);
char[] myArrayofChar = stat.ToCharArray();
Array.Reverse(myArrayofChar);
foreach (char myNewChar in myArrayofChar)
Console.Write(myNewChar); // You just need to write the function
// Write instead of WriteLine
Console.ReadKey();
}
}
}
This is the output:
#C ni nettirw sah edoc sihTedoc fo elpmaxe na si sihT
In C#7 There is a new Tuple
syntax:
static (string foo, int bar) GetTuple()
{
return ("hello", 5);
}
You can return this as a record:
var result = GetTuple();
var foo = result.foo
// foo == "hello"
You can also use the new deconstructor syntax:
(string foo) = GetTuple();
// foo == "hello"
Be careful with serialisation however, all this is syntactic sugar - in the actual compiled code this will be a Tuple<string, int>
(as per the accepted answer) with Item1
and Item2
instead of foo
and bar
. That means that serialisation (or deserialisation) will use those property names instead.
So, for serialisation declare a record class and return that instead.
Also new in C#7 is an improved syntax for out
parameters. You can now declare the out
inline, which is better suited in some contexts:
if(int.TryParse("123", out int result)) {
// Do something with result
}
However, mostly you'll use this in .NET's own libraries, rather than in you own functions.

Swift 3.0 answer: (from Vaibhav Gaikwad)
For changing color of unselect icons of tabbar:
if #available(iOS 10.0, *) {
UITabBar.appearance().unselectedItemTintColor = UIColor.white
} else {
// Fallback on earlier versions
for item in self.tabBar.items! {
item.image = item.image?.withRenderingMode(UIImageRenderingMode.alwaysOriginal)
}
}
For changing text color only:
UITabBarItem.appearance().setTitleTextAttributes([NSForegroundColorAttributeName: UIColor.white], for: .normal)
UITabBarItem.appearance().setTitleTextAttributes([NSForegroundColorAttributeName: UIColor.red, for: .selected)
This is the error you get (emphasis mine):
The ORDER BY clause is invalid in views, inline functions, derived tables, subqueries, and common table expressions, unless TOP or FOR XML is also specified.
So, how can you avoid the error? By specifying TOP, would be one possibility, I guess.
SELECT (
SELECT TOP 100 PERCENT
COUNT(1) FROM Seanslar WHERE MONTH(tarihi) = 4
GROUP BY refKlinik_id
ORDER BY refKlinik_id
) as dorduncuay
You have forgotten a *
between -3.7
and (prof[x])
.
Thus:
for x in range(len(prof)):
PB = 2.25 * (1 - math.pow(math.e, (-3.7 * (prof[x])/2.25))) * (math.e, (0/2.25)))
Also, there seems to be missing an (
as I count 6 times (
and 7 times )
, and I think (math.e, (0/2.25))
is missing a function call (probably math.pow
, but thats just a wild guess).
Toad for MySQL by Quest is free for non-commercial use. I really like the interface and it's quite powerful if you have several databases to work with (for example development, test and production servers).
From the website:
Toad® for MySQL is a freeware development tool that enables you to rapidly create and execute queries, automate database object management, and develop SQL code more efficiently. It provides utilities to compare, extract, and search for objects; manage projects; import/export data; and administer the database. Toad for MySQL dramatically increases productivity and provides access to an active user community.
If you have a list view you can do this:
Define a select list:
@{
var Acciones = new SelectList(new[]
{
new SelectListItem { Text = "Modificar", Value =
Url.Action("Edit", "Countries")},
new SelectListItem { Text = "Detallar", Value =
Url.Action("Details", "Countries") },
new SelectListItem { Text = "Eliminar", Value =
Url.Action("Delete", "Countries") },
}, "Value", "Text");
}
Use the defined SelectList, creating a diferent id for each record (remember that id of each element must be unique in a view), and finally call a javascript function for onchange event (include parameters in example url and record key):
@Html.DropDownList("ddAcciones", Acciones, "Acciones", new { id =
item.CountryID, @onchange = "RealizarAccion(this.value ,id)" })
onchange function can be something as:
@section Scripts {
<script src="~/Scripts/jquery-1.10.2.min.js"></script>
<script src="~/Scripts/jquery.unobtrusive-ajax.js"></script>
<script type="text/javascript">

It is terrible to install such Python data science packages independently on Windows. Try Anaconda (one installer, 400 more Python packages, py2 & py3 support). Anaconda really helps me a lot!

Here is how I was able to display a currency in an EditText that was easy to implement and works well for the user without the potential for crazy symbols all over the place. This will not try to do any formatting until the EditText no longer has focus. The user can still go back and make any edits without jeopardizing the formatting. I use the 'formattedPrice' variable for display only, and the 'itemPrice' variable as the value that I store/use for calculations.
It seems to be working really well, but I've only been at this for a few weeks, so any constructive criticism is absolutely welcome!
The EditText view in the xml has the following attribute:
android:inputType="numberDecimal"
Global variables:
private String formattedPrice;
private int itemPrice = 0;
In the onCreate method:
EditText itemPriceInput = findViewById(R.id.item_field_price);
itemPriceInput.setOnFocusChangeListener(new View.OnFocusChangeListener() {
@Override
public void onFocusChange(View v, boolean hasFocus) {
String priceString = itemPriceInput.getText().toString();
if (! priceString.equals("")) {
itemPrice = Double.parseDouble(priceString.replaceAll("[$,]", ""));
formattedPrice = NumberFormat.getCurrencyInstance().format(itemPrice);
itemPriceInput.setText(formattedPrice);
}
}
});
After a data connection update, some UDF's were not executing. Using a subroutine, I was trying to recalcuate a single column with:
Sheets("mysheet").Columns("D").Calculate
But above statement had no effect. None of above solutions helped, except kambeeks suggestion to replace formulas worked and was fast if manual recalc turned on during update. Below code solved my problem, even if not exactly responsible to OP "kluge" comment, it provided a fast/reliable solution to force recalculation of user-specified cells.
Application.Calculation = xlManual
DoEvents
For Each mycell In Sheets("mysheet").Range("D9:D750").Cells
mycell.Formula = mycell.Formula
Next
DoEvents
Application.Calculation = xlAutomatic
As your query string is a literal, and assuming your dates are properly stored as DATE
you should use date literals:
SELECT * FROM OrderArchive
WHERE OrderDate <= DATE '2015-12-31'
If you want to use TO_DATE
(because, for example, your query value is not a literal), I suggest you to explicitly set the NLS_DATE_LANGUAGE parameter as you are using US abbreviated month names. That way, it won't break on some localized Oracle Installation:
SELECT * FROM OrderArchive
WHERE OrderDate <= to_date('31 Dec 2014', 'DD MON YYYY',
'NLS_DATE_LANGUAGE = American');
The bitwise shift operators move the bit values of a binary object. The left operand specifies the value to be shifted. The right operand specifies the number of positions that the bits in the value are to be shifted. The result is not an lvalue. Both operands have the same precedence and are left-to-right associative.
Operator Usage
<< Indicates the bits are to be shifted to the left.
>> Indicates the bits are to be shifted to the right.
Each operand must have an integral or enumeration type. The compiler performs integral promotions on the operands, and then the right operand is converted to type int. The result has the same type as the left operand (after the arithmetic conversions).
The right operand should not have a negative value or a value that is greater than or equal to the width in bits of the expression being shifted. The result of bitwise shifts on such values is unpredictable.
If the right operand has the value 0, the result is the value of the left operand (after the usual arithmetic conversions).
The << operator fills vacated bits with zeros. For example, if left_op has the value 4019, the bit pattern (in 16-bit format) of left_op is:
0000111110110011
The expression left_op << 3 yields:
0111110110011000
The expression left_op >> 3 yields:
0000000111110110
While Loop example in T-SQL which list current month's beginning to end date.
DECLARE @Today DATE= GETDATE() ,
@StartOfMonth DATE ,
@EndOfMonth DATE;
DECLARE @DateList TABLE ( DateLabel VARCHAR(10) );

None of the following were my issue - I resolved this by opening an incognito window. Something was obviously being cached somewhere, no amount of changing auth client settings helped and there were never any trailing or leading spaces in config values.
As of jQuery 1.5, there is a headers
hash you can pass in as follows:
$.ajax({
url: "/test",
headers: {"X-Test-Header": "test-value"}
});
From http://api.jquery.com/jQuery.ajax:
headers (added 1.5): A map of additional header key/value pairs to send along with the request. This setting is set before the beforeSend function is called; therefore, any values in the headers setting can be overwritten from within the beforeSend function.

Actually, you can save you picture at any place. If you want to save in a public space, so any other application can access, use this code:
storageDir = new File(
Environment.getExternalStoragePublicDirectory(
Environment.DIRECTORY_PICTURES
),
getAlbumName()
);
The picture doesn't go to the album. To do this, you need to call a scan:
private void galleryAddPic() {
Intent mediaScanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
File f = new File(mCurrentPhotoPath);
Uri contentUri = Uri.fromFile(f);
mediaScanIntent.setData(contentUri);
this.sendBroadcast(mediaScanIntent);
}

It sounds like your error comes from an attempt to run something like this (which works in Linux)
NODE_ENV=development node foo.js
the equivalent in Windows would be
SET NODE_ENV=development
node foo.js
running in the same command shell. You mentioned set NODE_ENV did not work, but wasn't clear how/when you executed it.

The auto-indent is based on the current syntax mode. I know that if you are editing Foo.java, then entering a {
and hitting Enter indents the following line.
As for tabs, there are two settings. Within Vim, type a colon and then "set tabstop=4" which will set the tabs to display as four spaces. Hit colon again and type "set expandtab" which will insert spaces for tabs.
You can put these settings in a .vimrc (or _vimrc on Windows) in your home directory, so you only have to type them once.
If you don't need it to be an integer, but any random unique identifier, you can use newid()
SELECT table_name, newid() magic_number
FROM information_schema.tables
After some experimentation I found that a fourth value in the line controls the spread (at least in FF 10). I opposed the vertical offsets and gave them a negative spread.

To save space, you can even keep all files compressed. The following line uncompresses each file and counts its lines in parallel, then sums all counts.

From RFC 5321, section 2.3.11:
The standard mailbox naming convention is defined to be "local-part@domain"; contemporary usage permits a much broader set of applications than simple "user names". Consequently, and due to a long history of problems when intermediate hosts have attempted to optimize transport by modifying them, the local-part MUST be interpreted and assigned semantics only by the host specified in the domain part of the address.
So yes, the part before the "@" could be case-sensitive, since it is entirely under the control of the host system. In practice though, no widely used mail systems distinguish different addresses based on case.
The part after the @ sign however is the domain and according to RFC 1035, section 3.1,
"Name servers and resolvers must compare [domains] in a case-insensitive manner"
In short, you are safe to treat email addresses as case-insensitive.
Thank you for the suggested solutions! Unfortunately, none of them worked for my case: receiving a list of CLOB objects from Oracle database through JPA - Hibernate, using a native query.
All of the proposed approaches gave me either a ClassCastException or just returned java Proxy object (which deeply inside contained the desired Clob).
So my solution is the following (based on several above approaches):
Query sqlQuery = manager.createNativeQuery(queryStr);
List resultList = sqlQuery.getResultList();
for ( Object resultProxy : resultList ) {
String unproxiedClob = unproxyClob(resultProxy);
if ( unproxiedClob != null ) {
resultCollection.add(unproxiedClob);
}
}
private String unproxyClob(Object proxy) {
try {
BeanInfo beanInfo = Introspector.getBeanInfo(proxy.getClass());
for (PropertyDescriptor property : beanInfo.getPropertyDescriptors()) {
Method readMethod = property.getReadMethod();
if ( readMethod.getName().contains("getWrappedClob") ) {
Object result = readMethod.invoke(proxy);
return clobToString((Clob) result);
}
}
}
catch (InvocationTargetException | IntrospectionException | IllegalAccessException | SQLException | IOException e) {
LOG.error("Unable to unproxy CLOB value.", e);
}
return null;
}
private String clobToString(Clob data) throws SQLException, IOException {
StringBuilder sb = new StringBuilder();
Reader reader = data.getCharacterStream();
BufferedReader br = new BufferedReader(reader);
String line;
while( null != (line = br.readLine()) ) {
sb.append(line);
}
br.close();
return sb.toString();
}
Hope this will help somebody!

I've needed this and after some research I came up with this (jQuery needed):
First, right after the <body>
tag add this:
<div id="loading">
<img id="loading-image" src="images/ajax-loader.gif" alt="Loading..." />
</div>
Then add the style class for the div and image to your CSS:
#loading {
width: 100%;
height: 100%;
top: 0;
left: 0;
position: fixed;
display: block;
opacity: 0.7;
background-color: #fff;
z-index: 99;
text-align: center;
}
#loading-image {
position: absolute;
top: 100px;
left: 240px;
z-index: 100;
}
Then, add this javascript to your page (preferably at the end of your page, before your closing </body>
tag, of course):
<script>
$(window).load(function() {
$('#loading').hide();
});
</script>
Finally, adjust the position of the loading image and the background-colour
of the loading div with the style class.
This is it, should work just fine. But of course you have to have an ajax-loader.gif
somewhere. Freebies here. (Right-click > Save Image As...)

My suspicion is the problem lies in your route definition.
You defined the route as a GET
request but the form is probably sending a POST
request. Change your route definition to match the form's request method.
Route::post('/validate', [MemberController::class, 'validateCredentials']);
It's generally better practice to use named routes (helps to scale if the controller method/class changes).
Route::post('/validate', [MemberController::class, 'validateCredentials'])
->name('member.validateCredentials');
In the view, use the validation route as the form's action.
<form action="{{ route('member.validateCredentials') }}" method="POST">
@csrf
...
</form>
What worked for me was changing JAVA_HOME from file /usr/lib/R/etc/javaconf
I first checked what was my version of Java enabled : sudo update-alternatives --config java
.
In my case, it was java-8-oracle
I opened the file /usr/lib/R/etc/javaconf
and replaced default-java
by java-8-oracle
:
${JAVA_HOME=/usr/lib/jvm/default-java}
replaced by :
${JAVA_HOME=/usr/lib/jvm/java-8-oracle}
And then sudo R CMD javareconf
I restarted RStudio, and could then install rJava.
onmouseover="$('.play-detail').stop().animate({'height': '84px'},'300');"
onmouseout="$('.play-detail').stop().animate({'height': '44px'},'300');"
Just put two stops -- one onmouseover and one onmouseout.
List<String> items = Arrays.asList(commaSeparated.split(","));
That should work for you.
I could repro this by setting the name of input
tag the same for two groups of input like below:
<body>
<div>
<div>
<h3>Header1</h3>
</div>
<div>
<input type="radio" name="gender" id="male_1" value="male"> Male<br>
<input type="radio" name="gender" id="female_1" value="female" checked="checked"> Female<br>
<input type="submit" value="Submit">
</div>
</div>
<div>
<div>
<h3>Header2</h3>
</div>
<div>
<input type="radio" name="gender" id="male_2" value="male"> Male<br>
<input type="radio" name="gender" id="female_2" value="female" checked="checked"> Female<br>
<input type="submit" value="Submit">
</div>
</div>
</body>
(To see this running, click here)
The following two solutions both fix the problem:
form
tag instead of div
tag for one of the groups (can't really figure out the real reason why this would solve the problem. Would love to hear some opinions on this!)I would suggest you read this article and focus more on how to optimize the overall response to the user request (either a page, a search result etc.)
A good argument for this is the example they give about using gzip to compress the page. Even though ttfb is faster when you do not compress, the overall experience of the user is worst because it takes longer to download content that is not zipped.
I do the following for my .NET Standard 2.0 projects.
Create a Directory.Build.props

To test for existence there are two methods.
a. "property" in object
This method checks the prototype chain for existence of the property.
b. object.hasOwnProperty( "property" )
This method does not go up the prototype chain to check existence of the property, it must exist in the object you are calling the method on.
var x; // variable declared in global scope and now exists
"x" in window; // true
window.hasOwnProperty( "x" ); //true
If we were testing using the following expression then it would return false
typeof x !== 'undefined'; // false
Also, do not forget to mention that Google's V8 is VERY fast. It actually converts the JavaScript code to machine code with the matched performance of compiled binary. So along with all the other great things, it's INSANELY fast.

Using table aliases in the join condition:
update addresses a
set cid = b.id
from customers b
where a.id = b.id
This is what I typically do:
File outputDir = context.getCacheDir(); // context being the Activity pointer
File outputFile = File.createTempFile("prefix", "extension", outputDir);
As for their deletion, I am not complete sure either. Since I use this in my implementation of a cache, I manually delete the oldest files till the cache directory size comes down to my preset value.

BTW, I still can't use Set /A since FreeDOS doesn't support this command, but at least it supports the Set /P command.
This is a very common question seen on Stackoverflow.
The important part here is not the command displayed in the error, but what the actual error tells you instead.
a Quick breakdown on why this error is received.
cmd.exe
Being a terminal window relies on input and system Environment variables, in order to perform what you request it to do. it does NOT know the location of everything and it also does not know when to distinguish between commands or executable names which are separated by whitespace like space and tab or commands with whitespace as switch variables.
How do I fix this:
When Actual Command/executable fails
First we make sure, is the executable actually installed? If yes, continue with the rest, if not, install it first.
If you have any executable which you are attempting to run from cmd.exe
then you need to tell cmd.exe
where this file is located. There are 2 ways of doing this.
specify the full path to the file.
"C:\My_Files\mycommand.exe"
Add the location of the file to your environment Variables.
Goto:
------> Control Panel-> System-> Advanced System Settings->Environment Variables
In the System Variables
Window, locate path
and select edit
Now simply add your path to the end of the string, seperated by a semicolon ;
as:
;C:\My_Files\
Save the changes and exit. You need to make sure that ANY cmd.exe
windows you had open are then closed and re-opened to allow it to re-import the environment variables.
Now you should be able to run mycommand.exe from any path, within cmd.exe
as the environment is aware of the path to it.
When C:\Program
or Similar fails
This is a very simple error. Each string after a white space is seen as a different command in cmd.exe
terminal, you simply have to enclose the entire path in double quotes in order for cmd.exe
to see it as a single string, and not separate commands.
So to execute C:\Program Files\My-App\Mobile.exe
simply run as:
"C:\Program Files\My-App\Mobile.exe"
What about this? I never found this patter around but I was just trying to exclude one or more properties without the need of creating an extra object. This seems to do the job but there are some side effects I'm not able to see. For sure is not very readable.
const postData = {
token: 'secret-token',
publicKey: 'public is safe',
somethingElse: true,
};
const a = {
...(({token, ...rest} = postData) => (rest))(),
}
/**
a: {
publicKey: 'public is safe',
somethingElse: true,
}
*/
I simplified my source code (whose original version is OOP and uses a configuration file), to give you an alternative solution to @EliasStrehle's one, without using the dictConfig (thus easiest to integrate with existing source code):
import logging
import sys
def create_stream_handler(stream, formatter, level, message_filter=None):
handler = logging.StreamHandler(stream=stream)
handler.setLevel(level)
handler.setFormatter(formatter)
if message_filter:
handler.addFilter(message_filter)
return handler
def configure_logger(logger: logging.Logger, enable_console: bool = True, enable_file: bool = True):
if not logger.handlers:
if enable_console:
message_format: str = '{asctime:20} {name:16} {levelname:8} {message}'
date_format: str = '%Y/%m/%d %H:%M:%S'
level: int = logging.DEBUG
formatter = logging.Formatter(message_format, date_format, '{')
# Configures error output (from Warning levels).
error_output_handler = create_stream_handler(sys.stderr, formatter,
max(level, logging.WARNING))
logger.addHandler(error_output_handler)
# Configures standard output (from configured Level, if lower than Warning,
# and excluding everything from Warning and higher).
if level < logging.WARNING:
standard_output_filter = lambda record: record.levelno < logging.WARNING
standard_output_handler = create_stream_handler(sys.stdout, formatter, level,
standard_output_filter)
logger.addHandler(standard_output_handler)
if enable_file:
message_format: str = '{asctime:20} {name:16} {levelname:8} {message}'
date_format: str = '%Y/%m/%d %H:%M:%S'
level: int = logging.DEBUG
output_file: str = '/tmp/so_test.log'
handler = logging.FileHandler(output_file)
formatter = logging.Formatter(message_format, date_format, '{')
handler.setLevel(level)
handler.setFormatter(formatter)
logger.addHandler(handler)
This is a very simple way to test it:
logger: logging.Logger = logging.getLogger('MyLogger')
logger.setLevel(logging.DEBUG)
configure_logger(logger, True, True)
logger.debug('Debug message ...')
logger.info('Info message ...')
logger.warning('Warning ...')
logger.error('Error ...')
logger.fatal('Fatal message ...')
From the RFC 4648:
Base encoding of data is used in many situations to store or transfer data in environments that, perhaps for legacy reasons, are restricted to US-ASCII data.
So it depends on the purpose of usage of the encoded data if the data should be considered as dangerous.
But if you’re just looking for a regular expression to match Base64 encoded words, you can use the following:
^(?:[A-Za-z0-9+/]{4})*(?:[A-Za-z0-9+/]{2}==|[A-Za-z0-9+/]{3}=)?$
I encountered this issue by putting a XML file into the src/main/resources
wrongly, I deleted it and then all back to normal.
This problem becomes apparent when you try to host a react app in github pages.
How I fixed this,
In in my main application file, called app.tsx
, where I include the router.
I set the basename, eg,
<BrowserRouter basename="/Seans-TypeScript-ReactJS-Redux-Boilerplate/">
Note that it is a relative url, this completely simplifies the ability to run locally and hosted. The basename value, matches the repository title on GitHub. This is the path that GitHub pages will auto create.
That is all I needed to do.
See working example hosted on GitHub pages at
https://sean-bradley.github.io/Seans-TypeScript-ReactJS-Redux-Boilerplate/
Better yet, use union to grab all the rows you want to delete, then delete them all at once. The rows need not be continuous.
dim rng as range
dim rDel as range
for each rng in {the range you're searching}
if {Conditions to be met} = true then
if not rDel is nothing then
set rDel = union(rng,rDel)
else
set rDel = rng
end if
end if
next
rDel.entirerow.delete
That way you don't have to worry about sorting or things being at the bottom.
If you have included jQuery, there may be a conflict. Try using jQuery
instead of $

it has changed and its docked to the right bottom of your android studio by default.
if you dont have that you can open it through view -> tool windows -> device file explorer
If I get your question correctly, you want to also know the names of the files generated inside the temporary directory? If so, try this:
import os
import tempfile
with tempfile.TemporaryDirectory() as tmp_dir:
# generate some random files in it
files_in_dir = os.listdir(tmp_dir)
Setting CSS width to 1% or 100% of an element according to all specs I could find out is related to the parent. Although Blink Rendering Engine (Chrome) and Gecko (Firefox) at the moment of writing seems to handle that 1% or 100% (make a columns shrink or a column to fill available space) well, it is not guaranteed according to all CSS specifications I could find to render it properly.
One option is to replace table with CSS4 flex divs:
https://css-tricks.com/snippets/css/a-guide-to-flexbox/
That works in new browsers i.e. IE11+ see table at the bottom of the article.
I needed to do the same thing for a chart where you could select the period of the data that should be displayed.
Therefore I introduced the CSS class 'btn-group-radio' and used the following unobtrusive javascript one-liner:
// application.js
$(document).ready(function() {
$('.btn-group-radio .btn').click(function() {
$(this).addClass('active').siblings('.btn').removeClass('active');
});
});
And here is the HTML:
<!-- some arbitrary view -->
<div class="btn-group btn-group-radio">
<%= link_to '1W', charts_path('1W'), class: 'btn btn-default active', remote: true %>
<%= link_to '1M', charts_path('1M'), class: 'btn btn-default', remote: true %>
<%= link_to '3M', charts_path('3M'), class: 'btn btn-default', remote: true %>
<%= link_to '6M', charts_path('6M'), class: 'btn btn-default', remote: true %>
<%= link_to '1Y', charts_path('1Y'), class: 'btn btn-default', remote: true %>
<%= link_to 'All', charts_path('all'), class: 'btn btn-default', remote: true %>
</div>
Clickatell is a popular SMS gateway. It works in 200+ countries.
Their API offers a choice of connection options via: HTTP/S, SMPP, SMTP, FTP, XML, SOAP. Any of these options can be used from php.
The HTTP/S method is as simple as this:
http://api.clickatell.com/http/sendmsg?to=NUMBER&msg=Message+Body+Here
The SMTP method consists of sending a plain-text e-mail to: [email protected]
, with the following body:
user: xxxxx
password: xxxxx
api_id: xxxxx
to: 448311234567
text: Meet me at home
You can also test the gateway (incoming and outgoing) for free from your browser
Intuitively, we can see that if a problem is in P, then it is in NP. Given a potential answer for a problem in P, we can verify the answer by simply recalculating the answer.
Less obvious, and much more difficult to answer, is whether all problems in NP are in P. Does the fact that we can verify an answer in polynomial time mean that we can compute that answer in polynomial time?
There are a large number of important problems that are known to be NP-complete (basically, if any these problems are proven to be in P, then all NP problems are proven to be in P). If P = NP, then all of these problems will be proven to have an efficient (polynomial time) solution.
Most scientists believe that P!=NP. However, no proof has yet been established for either P = NP or P!=NP. If anyone provides a proof for either conjecture, they will win US $1 million.
try this:
public boolean verifyPwd(){
if (!(pword.equals(pwdRetypePwd.getText()))){
txtaError.setEditable(true);
txtaError.setText("*Password didn't match!");
txtaError.setForeground(Color.red);
txtaError.setEditable(false);
return false;
}
else {
return true;
}
}
if (verifyPwd()==true){
addNewUser();
}
else {
// passwords do not match
}
As said before, @Column(unique = true)
is a shortcut to UniqueConstraint
when it is only a single field.
From the example you gave, there is a huge difference between both.
@Column(unique = true)
@ManyToOne(optional = false, fetch = FetchType.EAGER)
private ProductSerialMask mask;
@Column(unique = true)
@ManyToOne(optional = false, fetch = FetchType.EAGER)
private Group group;
This code implies that both mask
and group
have to be unique, but separately. That means that if, for example, you have a record with a mask.id = 1 and tries to insert another record with mask.id = 1, you'll get an error, because that column should have unique values. The same aplies for group.
On the other hand,
@Table(
name = "product_serial_group_mask",
uniqueConstraints = {@UniqueConstraint(columnNames = {"mask", "group"})}
)
Implies that the values of mask + group combined should be unique. That means you can have, for example, a record with mask.id = 1 and group.id = 1, and if you try to insert another record with mask.id = 1 and group.id = 2, it'll be inserted successfully, whereas in the first case it wouldn't.
If you'd like to have both mask and group to be unique separately and to that at class level, you'd have to write the code as following:
@Table(
name = "product_serial_group_mask",
uniqueConstraints = {
@UniqueConstraint(columnNames = "mask"),
@UniqueConstraint(columnNames = "group")
}
)
This has the same effect as the first code block.
var newObj = { a: 4, b: 0.5 , c: 0.35, d: 5 };
var maxValue = Math.max(...Object.values(newObj))
var minValue = Math.min(...Object.values(newObj))
If you have a form as such:
<form id="myform">
...
</form>
You can use the following jQuery code to do something before the form is submitted:
$('#myform').submit(function() {
// DO STUFF...
return true; // return false to cancel form action
});
You may want to look into os dependent line separators, e.g.:
import os
with open('./output.txt', 'a') as f1:
f1.write(content + os.linesep)

I was able to toggle this error by changing a single thing. In my ASP.Net Core 1.0 RC2 Web Application project's launchSettings.json
file:
"iisSettings": {
"windowsAuthentication": false,
"anonymousAuthentication": true,
"iisExpress": {
"applicationUrl": "https://localhost:18177/",
"sslPort": 0
}
},
to
"iisSettings": {
"windowsAuthentication": false,
"anonymousAuthentication": true,
"iisExpress": {
"applicationUrl": "http://localhost:18177/",
"sslPort": 0
}
},
I had changed to https in an attempt to run the project using that protocol. Apparently this is not the place to make that change. I suspect it is creating multiple bindings on the same port, and IIS Express doesn't like that.
You'd have to test it but if you embedded an iframe within your page then used CSS to absolutely position the 1st row & column at 0,0 in the iframe page would that solve your problem?
You can use the Core/index function in a given context, for example you can check the index of the TD in it's parent TR to get the column number, and you can check the TR index on the Table, to get the row number:
$('td').click(function(){
var col = $(this).parent().children().index($(this));
var row = $(this).parent().parent().children().index($(this).parent());
alert('Row: ' + row + ', Column: ' + col);
});

The quick select algorithm can find the k-th smallest element of an array in linear (O(n)
) running time. Here is an implementation in python:
import random
def partition(L, v):
smaller = []
bigger = []
for val in L:
if val < v: smaller += [val]
if val > v: bigger += [val]
return (smaller, [v], bigger)
def top_k(L, k):
v = L[random.randrange(len(L))]
(left, middle, right) = partition(L, v)
# middle used below (in place of [v]) for clarity
if len(left) == k: return left
if len(left)+1 == k: return left + middle
if len(left) > k: return top_k(left, k)
return left + middle + top_k(right, k - len(left) - len(middle))
def median(L):
n = len(L)
l = top_k(L, n / 2 + 1)
return max(l)
Have you seen FlexSlider from WooThemes? I've used it on several recent projects with great success. It's touch enabled too so it will work on both mouse-based browsers as well as touch-based browsers in iOS and Android.

Select the correct package manager to install pymysql with:
sudo pip install pymysql
.sudo pip3 install pymysql
.sudo conda install pymysql
.sudo apt-get install pymysql
.If all else fails, install the package directly:
sudo python3 setup.py install
.This answer is a compilation of suggestions. Apart from the other ones proposed here, thanks to the comment by @cmaher on this related thread.
First Google hit says:
this is usually a mismatch in the client/server bindings, where the message version in the service uses SOAP 1.2 (which expects application/soap+xml) and the version in the client uses SOAP 1.1 (which sends text/xml). WSHttpBinding uses SOAP 1.2, BasicHttpBinding uses SOAP 1.1.
It usually seems to be a wsHttpBinding on one side and a basicHttpBinding on the other.

Ok I'm not sure what's up with these answers but I'll let you know what worked for me as advised by a senior dev at my work. I'm working in Ruby on Rails and using Facebook's JavaScript code to get access tokens.
Problem: To do authentication, Facebook is taking the url from your address bar and comparing that with what they have on file. They don't allow you to use localhost:3000
for whatever reason. However, you can use a completely made-up domain name like yoursite.dev
by running a local server and pointing yoursite.dev
to 127.0.0.1:3000
or wherever your localhost was pointing to.
Step 1: Install or update Nginx
$ brew install nginx
(install) or $ brew upgrade nginx
(update)
Step 2: Open up your nginx config file
/usr/local/etc/nginx/nginx.conf
(usually here)
/opt/boxen/config/nginx/nginx.conf
(if you use Boxen)
Step 3 Add this bit of code into your http {}
block
Replace proxy_pass
with wherever you want to point yoursite.dev
to. In my case it was replacing localhost:3000 or the equivalent 127.0.0.1:3000
server {
listen yoursite.dev:80;
server_name yoursite.dev;
location / {
proxy_pass http://127.0.0.1:3000;
}
}
Step 4: Edit your hosts file, in /etc/hosts
on Mac to include
127.0.0.1 yoursite.dev
This file directs domains to localhost. Nginx listens in on localhost and redirects if it matches a rule.
Step 5: Every time you use your dev environment going forward, you use the yoursite.dev
in the address bar instead of localhost:3000
so Facebook logs you in correctly.
A = zeros(20, 10, 3); %# Creates a 20x10x3 matrix
B = zeros(4,4);
C = zeros(size(B,1), size(B,2), 4); %# New matrix with B's size, and 3rd dimension of size 4
C(:,:,1) = B; %# Copy the content of B into C's first set of values
zeros is just one way of making a new matrix. Another could be A(1:20,1:10,1:3) = 0
for a 3D matrix. To confirm the size of your matrices you can run: size(A)
which gives 20 10 3
.
There is no explicit bound on the number of dimensions a matrix may have.
This work for me.

Try this:
$('#form').submit(function(eventObj) {
$(this).append('<input type="hidden" name="field_name" value="value" /> ');
return true;
});
You can make function getStyles
that'll take an element and other arguments are properties that's values you want.
const convertRestArgsIntoStylesArr = ([...args]) => {
return args.slice(1);
}
const getStyles = function () {
const args = [...arguments];
const [element] = args;
let stylesProps = [...args][1] instanceof Array ? args[1] : convertRestArgsIntoStylesArr(args);
const styles = window.getComputedStyle(element);
const stylesObj = stylesProps.reduce((acc, v) => {
acc[v] = styles.getPropertyValue(v);
return acc;
}, {});
return stylesObj;
};
Now, you can use this function like this:
const styles = getStyles(document.body, "height", "width");
OR
const styles = getStyles(document.body, ["height", "width"]);
i := 23
i64 := int64(i)

The gap between the (bootstrap) input field and jquery-ui autocompleter seem to occur only in jQuery versions >= 3.2
When using jQuery version 3.1.1 it seem to not happen.
Possible reason is the notable update in v3.2.0 related to a bug fix on .width()
and .height()
. Check out the jQuery release notes for further details: v3.2.0 / v3.1.1

You need to use the \ to escape the double quote character in a string.
char (with a lower-case c) is a numeric type. It already holds the ascii value of the char. Just cast it to an integer to display it as a numeric value rather than a textual value:
System.out.println("char " + ch + " has the following value : " + (int) ch);
A BufferedReader constructor takes a reader as argument, not an InputStream. You should first create a Reader from your stream, like so:
Reader reader = new InputStreamReader(is);
BufferedReader br = new BufferedReader(reader);
Preferrably, you also provide a Charset or character encoding name to the StreamReader constructor. Since a stream just provides bytes, converting these to text means the encoding must be known. If you don't specify it, the system default is assumed.

Here is a way to create your Custom Pagination Component from react-bootstrap lib and this component you can use Throughout your project
Your Pagination Component (pagination.jsx or js)
import React, { Component } from "react";
import { Pagination } from "react-bootstrap";
import PropTypes from "prop-types";
export default class PaginationHandler extends Component {
constructor(props) {
super(props);
this.state = {
paging: {
offset: 0,
limit: 10
},
active: 0
};
}
pagingHandler = () => {
let offset = parseInt(event.target.id);
this.setState({
active: offset
});
this.props.pageHandler(event.target.id - 1); };
nextHandler = () => {
let active = this.state.active;
this.setState({
active: active + 1
});
this.props.pageHandler(active + 1); };
backHandler = () => {
let active = this.state.active;
this.setState({
active: active - 1
});
this.props.pageHandler(active - 1); };
renderPageNumbers = (pageNumbers, totalPages) => {
let { active } = this.state;
return (
<Pagination>
<Pagination.Prev disabled={active < 5} onClick={ active >5 && this.backHandler} />
{
pageNumbers.map(number => {
if (
number >= parseInt(active) - 3 &&
number <= parseInt(active) + 3
) {
return (
<Pagination.Item
id={number}
active={number == active}
onClick={this.pagingHandler}
>
{number}
</Pagination.Item>
);
} else {
return null;
}
})}
<Pagination.Next onClick={ active <= totalPages -4 && this.nextHandler} />
</Pagination>
); };
buildComponent = (props, state) => {
const { totalPages } = props;
const pageNumbers = [];
for (let i = 1; i <= totalPages; i++) {
pageNumbers.push(i);
}
return (
<div className="pull-right">
{this.renderPageNumbers(pageNumbers ,totalPages)}
</div>
);
};
render() {
return this.buildComponent(this.props, this.state);
}
}
PaginationHandler.propTypes =
{
paging: PropTypes.object,
pageHandler: PropTypes.func,
totalPages: PropTypes.object
};
Use of Above Component in your Component
import Pagination from "../pagination";
pageHandler = (offset) =>{
this.setState(({ paging }) => ({
paging: { ...paging, offset: offset }
}));
}
render() {
return (
<div>
<Pagination
paging = {paging}
pageHandler = {this.pageHandler}
totalPages = {totalPages}>
</Pagination>
</div>
);
}

I ran into this and it was caused by the entity's ID (key) field not being set. Thus when the context went to save the data, it could not find an ID = 0. Be sure to place a break point in your update statement and verify that the entity's ID has been set.
From Paul Bellora's comment
I had this exact issue, caused by forgetting to include the hidden ID input in the .cshtml edit page
Try using a return statement. It works best. It stops the function when the condition is met.
function anything() {
var get = document.getElementsByClassName("text ").value;
if (get == null) {
alert("Please put in your name");
}
return;
var random = Math.floor(Math.random() * 100) + 1;
console.log(random);
}
Unfortunately you're probably done with the animation and presentation already. In the hopes this answer can help future questioners, however, this blog post has a walkthrough of steps that can loop a single slide as a sort of sub-presentation.
First, click Slide Show > Set Up Show.
Put a checkmark to Loop continuously until 'Esc'.
Click Ok. Now, Click Slide Show > Custom Shows. Click New.
Select the slide you are looping, click Add. Click Ok and Close.
Click on the slide you are looping. Click Slide Show > Slide Transition. Under Advance slide, put a checkmark to Automatically After. This will allow the slide to loop automatically. Do NOT Apply to all slides.
Right click on the thumbnail of the current slide, select Hide Slide.
Now, you will need to insert a new slide just before the slide you are looping. On the new slide, insert an action button. Set the hyperlink to the custom show you have created. Put a checkmark on "Show and Return"
This has worked for me.
You can use jsoup

You can parse according to tag/parent/child very comfortably
This is directly from http://www.programcreek.com/2011/10/java-class-instance-initializers/
Look at the following class, do you know which one gets executed first?
public class Foo {
//instance variable initializer
String s = "abc";
//constructor
public Foo() {
System.out.println("constructor called");
}
//static initializer
static {
System.out.println("static initializer called");
}
//instance initializer
{
System.out.println("instance initializer called");
}
public static void main(String[] args) {
new Foo();
new Foo();
}
}
Output:
static initializer called
instance initializer called
constructor called
instance initializer called
constructor called
The instance initializer above contains a println statement. To understand how it works, we can treat it as a variable assignment statement, e.g., b = 0
. This can make it more obvious to understand.
Instead of
int b = 0
, you could write
int b;
b = 0;
Therefore, instance initializers and instance variable initializers are pretty much the same.
The use of instance initializers are rare, but still it can be a useful alternative to instance variable initializers if:
Of course, such code could be written in constructors. But if a class had multiple constructors, you would have to repeat the code in each constructor.
With an instance initializer, you can just write the code once, and it will be executed no matter what constructor is used to create the object. (I guess this is just a concept, and it is not used often.)
Another case in which instance initializers are useful is anonymous inner classes, which can’t declare any constructors at all. (Will this be a good place to place a logging function?)
Thanks to Derhein.
Also note that Anonymous classes that implement interfaces [1] have no constructors. Therefore instance initializers are needed to execute any kinds of expressions at construction time.
Not to bring up an old post but I landed on this question in my search for the same solution. I ended up coming up with something of my own. Figured I'd contribute.

Swift 5 : For evenly distributed spaces between cells with dynamic cell width to make the best of container space you may use the code snippet below by providing a minimumCellWidth value.
private func collectionViewLayout() -> UICollectionViewLayout {
let layout = UICollectionViewFlowLayout()
layout.sectionHeadersPinToVisibleBounds = true
// Important: if direction is horizontal use minimumItemSpacing instead.
layout.scrollDirection = .vertical
let itemHeight: CGFloat = 240
let minCellWidth :CGFloat = 130.0
let minItemSpacing: CGFloat = 10
let containerWidth: CGFloat = self.view.bounds.width
let maxCellCountPerRow: CGFloat = floor((containerWidth - minItemSpacing) / (minCellWidth+minItemSpacing ))
let itemWidth: CGFloat = floor( ((containerWidth - (2 * minItemSpacing) - (maxCellCountPerRow-1) * minItemSpacing) / maxCellCountPerRow ) )
// Calculate the remaining space after substracting calculating cellWidth (Divide by 2 because of left and right insets)
let inset = max(minItemSpacing, floor( (containerWidth - (maxCellCountPerRow*itemWidth) - (maxCellCountPerRow-1)*minItemSpacing) / 2 ) )
layout.itemSize = CGSize(width: itemWidth, height: itemHeight)
layout.minimumInteritemSpacing = min(minItemSpacing,inset)
layout.minimumLineSpacing = minItemSpacing
layout.sectionInset = UIEdgeInsets(top: minItemSpacing, left: inset, bottom: minItemSpacing, right: inset)
return layout
}
If you have MFA enabled on GitLab you should go to Repository Settings/Repository ->Deploy Keys and create one, then use it as login while importing repo on GitHub
In regards to the first comment: If you do this you will get an error(in Android Studio). This is in regards to it being out of the Android namespace. If you don't know how to fix this error, check the example out below. Hope this helps!
Example -Before :
<string-array name="roomSize">
<item>Small(0-4)</item>
<item>Medium(4-8)</item>
<item>Large(9+)</item>
</string-array>
Example - After:
<string-array android:name="roomSize">
<item>Small(0-4)</item>
<item>Medium(4-8)</item>
<item>Large(9+)</item>
</string-array>
I had similar issue but I could not resolve it using static ip address or changing firewall settings. I found a useful utility which can be configured in a minute.
We can host our local web server on cloud for free. On exposing it on cloud we get a different URL which we can use instead of localhost and access the webserver from anywhere.
The utility is ngrok https://ngrok.com/download Steps:
URL like : http://localhost/php/test.php Should be modified like this : http://fafb42f.ngrok.io/php/test.php
Now this URL can be accessed from phone.
This will do:
/^(apple|banana)$/
to exclude from captured strings (e.g. $1
,$2
):
(?:apple|banana)
What sort of rounding behavior do you want? Do you 2.67 to turn into 3, or 2. If you want to use rounding, try this:
s = '234.67'
i = int(round(float(s)))
Otherwise, just do:
s = '234.67'
i = int(float(s))
You are using this :
mysql_fetch_array($result)
To get the error you're getting, it means that $result
is not a resource.
In your code, $result
is obtained this way :
$result = mysql_query("SELECT * FROM student WHERE IDNO=".$_GET['id']);
If the SQL query fails, $result
will not be a resource, but a boolean -- see mysql_query
.
I suppose there's an error in your SQL query -- so it fails, mysql_query
returns a boolean, and not a resource, and mysql_fetch_array
cannot work on that.
You should check if the SQL query returns a result or not :
$result = mysql_query("SELECT * FROM student WHERE IDNO=".$_GET['id']);
if ($result !== false) {
// use $result
} else {
// an error has occured
echo mysql_error();
die; // note : echoing the error message and dying
// is OK while developping, but not in production !
}
With that, you should get a message that indicates the error that occured while executing your query -- this should help figure out what the problem is ;-)
Also, you should escape the data you're putting in your SQL query, to avoid SQL injections !
For example, here, you should make sure that $_GET['id']
contains nothing else than an integer, using something like this :
$result = mysql_query("SELECT * FROM student WHERE IDNO=" . intval($_GET['id']));
Or you should check this before trying to execute the query, to display a nicer error message to the user.
PsFile does work on remote machines. If my login account already has access to the remote share, I can just enter:
psfile \\remote-share
(replace "remote-share" with the name of your file server) and it will list every opened document on that share, along with who has it open, and the file ID if I want to force the file closed. For me, this is a really long list, but it can be narrowed down by entering part of a path:
psfile \\remote-share I:\\Human_Resources
This is kind of tricky, since in my case this remote share is mounted as Z: on my local machine, but psfile identifies paths as they are defined on the remote file server, which in my case is I: (yours will be different). I just had to comb through the results of my first psfile run to see some of the paths it returned and then run it again with a partial path to narrow down the results.
Optionally, PsFile will let you specify credentials for the remote share if you need to supply them for access.
Lastly, a little known tip: if someone clicks on a file in Windows Explorer and cuts or copies the file with the intent to paste it somewhere else, that act also places a lock on the file.
I got the same problem before, but I change the url into this
https://api.instagram.com/oauth/authorize/?client_id=CLIENT-ID&redirect_uri=REDIRECT-URI&response_type=token
The loopj library can be used straight-forward for this purpose:
SyncHttpClient client = new SyncHttpClient();
RequestParams params = new RequestParams();
params.put("text", "some string");
params.put("image", new File(imagePath));
client.post("http://example.com", params, new TextHttpResponseHandler() {
@Override
public void onFailure(int statusCode, Header[] headers, String responseString, Throwable throwable) {
// error handling
}
@Override
public void onSuccess(int statusCode, Header[] headers, String responseString) {
// success
}
});
Instead of using success
, I change it to then
and it works.
here is the code:
lgrg.controller('login', function($scope, $window, $http) {
$scope.loginUser = {};
$scope.submitForm = function() {
$scope.errorInfo = null
$http({
method : 'POST',
url : '/login',
headers : {'Content-Type': 'application/json'}
data: $scope.loginUser
}).then(function(data) {
if (!data.status) {
$scope.errorInfo = data.info
} else {
//page jump
$window.location.href = '/admin';
}
});
};
});
see http://api.jquery.com/prev/
var link = $("#me").parent("div").prev("h3").find("b");
alert(link.text());
You normally use a tool like pip
to install wheels. Leave it to the tool to discover and download the file if this is for a project hosted on PyPI.
For this to work, you do need to install the wheel
package:
pip install wheel
You can then tell pip
to install the project (and it'll download the wheel if available), or the wheel file directly:
pip install project_name # discover, download and install
pip install wheel_file.whl # directly install the wheel
The wheel
module, once installed, also is runnable from the command line, you can use this to install already-downloaded wheels:
python -m wheel install wheel_file.whl
Also see the wheel
project documentation.
Use Random.nextInt(int).
In your case it would look something like this:
a[i][j] = r.nextInt(101);
For what I know printing the complete stack trace in nodejs is not possible, you can just print a "partial" stack trace, you can not see from where you came from in the code, just where the Exception occur. That's what Ryan Dahl explains in this youtube video. http://youtu.be/jo_B4LTHi3I at min 56:30 for being precise. Hope this helps
I think that what you are looking for is the Strategy Pattern.
This can be implemented in a number of ways, which have been mentionned in other answers to this question, such as:
If you're doing some sort of math with the numbers you might also want to know the units. Given your input restrictions (that the input string contains unit and value only), this should correctly return both (you'll just need to figure out how to convert units into common units for your math).
def unit_value(str):
m = re.match(r'([^\d]*)(\d*\.?\d+)([^\d]*)', str)
if m:
g = m.groups()
return ' '.join((g[0], g[2])).strip(), float(g[1])
else:
return int(str)
You don't need to output php
tags:
<?php
if ( has_post_thumbnail() )
{
echo '<div class="gridly-image"><a href="'. the_permalink() .'">'. the_post_thumbnail('summary-image', array('class' => 'overlay', 'title'=> the_title('Read Article ',' now',false) )) .'</a></div>';
}
echo '<div class="date">
<span class="day">'. the_time('d') .'</span>
<div class="holder">
<span class="month">'. the_time('M') .'</span>
<span class="year">'. the_time('Y') .'</span>

The @
operator calls the array's __matmul__
method, not dot
. This method is also present in the API as the function np.matmul
.
>>> a = np.random.rand(8,13,13)
>>> b = np.random.rand(8,13,13)
>>> np.matmul(a, b).shape
(8, 13, 13)
From the documentation:
matmul
differs fromdot
in two important ways.
- Multiplication by scalars is not allowed.
- Stacks of matrices are broadcast together as if the matrices were elements.
The last point makes it clear that dot
and matmul
methods behave differently when passed 3D (or higher dimensional) arrays. Quoting from the documentation some more:
For matmul
:
If either argument is N-D, N > 2, it is treated as a stack of matrices residing in the last two indexes and broadcast accordingly.
For np.dot
:
For 2-D arrays it is equivalent to matrix multiplication, and for 1-D arrays to inner product of vectors (without complex conjugation). For N dimensions it is a sum product over the last axis of a and the second-to-last of b

The best way to create internal links (related with sections) is create list but instead of link, put #section
or #section-title
if the header includes spaces.
Markdown
Go to section
* [Hello](#hello)
* [Hello World](#hello-world)
* [Another section](#new-section) <-- it's called 'Another section' in this list but refers to 'New section'
## Hello
### Hello World
## New section
List preview
Go to section
Hello <-- [Hello](#hello) -- go to `Hello` section
Hello World <-- [Hello World](#hello world) -- go to `Hello World` section
Another section <-- [Another section](#new-section) -- go to `New section`
HTML
<p>Go to section</p>
<ul>
<li><a href="#hello">Hello</a></li>
<li><a href="#hello-world">Hello World</a></li>
<li><a href="#new-section">Another section</a> <– it’s called ‘Another section’ in this list but refers to ‘New section’</li>
</ul>
<h2 id="hello">Hello</h2>
<h3 id="hello-world">Hello World</h3>
<h2 id="new-section">New section</h2>
It doesn't matter whether it's h1
, h2
, h3
, etc. header, you always refer to it using just one #
.
All references in section list should be converted to lowercase text as it is shown in the example above.
The link to the section should be lowercase. It won't work otherwise. This technique works very well for all Markdown variants, also MultiMarkdown.
Currently I'm using the Pandoc to convert documents format. It's much better than MultiMarkdown.

Node.js has included experimental support for ES6 support. Read more about here: https://nodejs.org/docs/latest-v13.x/api/esm.html#esm_enabling.
TLDR;
Node.js >= v13
It's very simple in Node.js 13 and above. You need to either:
.mjs
extension, or{ "type": "module" }
in the nearest package.json
.You only need to do one of the above to be able to use ECMAScript modules.
Node.js <= v12
If you are using Node.js version 8-12, save the file with ES6 modules with .mjs
extension and run it like:
node --experimental-modules my-app.mjs
Knockout.js validation is handy but it is not robust. You always have to create server side validation replica. In your case (as you use knockout.js) you are sending JSON data to server and back asynchronously, so you can make user think that he sees client side validation, but in fact it would be asynchronous server side validation.
Take a look at example here upida.cloudapp.net:8080/org.upida.example.knockout/order/create?clientId=1 This is a "Create Order" link. Try to click "save", and play with products. This example is done using upida library (there are spring mvc version and asp.net mvc of this library) from codeplex.
Try trimming the string to make sure there is no extra white space:
Cursor c = db.rawQuery("SELECT * FROM tbl1 WHERE TRIM(name) = '"+name.trim()+"'", null);
Also use c.moveToFirst()
like @thinksteep mentioned.
This is a complete code for select statements.
SQLiteDatabase db = this.getReadableDatabase();
Cursor c = db.rawQuery("SELECT column1,column2,column3 FROM table ", null);
if (c.moveToFirst()){
do {
// Passing values
String column1 = c.getString(0);
String column2 = c.getString(1);
String column3 = c.getString(2);
// Do something Here with values
} while(c.moveToNext());
}
c.close();
db.close();
When trying to set up a .NET Core 1.0 website I got this error, and tried everything else I could find with no luck, including checking the web.config file, IIS_IUSRS permissions, IIS URL rewrite module, etc. In the end, I installed DotNetCore.1.0.0-WindowsHosting.exe from this page: https://www.microsoft.com/net/download and it started working right away.

If you need dynamic collection, you should consider using one of java.util.Collection implementations that fits your problem. E.g. java.util.List.
Identifying the column is easy:
SELECT *
FROM ( SELECT id,
time
FROM dbo.a
UNION
SELECT id,
time
FROM dbo.b
)
GROUP BY id
But it doesn't solve the main problem of this query: what's to be done with the second column values upon grouping by the first? Since (peculiarly!) you're using UNION
rather than UNION ALL
, you won't have entirely duplicated rows between the two subtables in the union, but you may still very well have several values of time for one value of the id, and you give no hint of what you want to do - min, max, avg, sum, or what?! The SQL engine should give an error because of that (though some such as mysql just pick a random-ish value out of the several, I believe sql-server is better than that).
So, for example, change the first line to SELECT id, MAX(time)
or the like!
If you don't mind importing then fileinput does exactly what you need (this is you can read the line number of the current line)
I know this is too late. But i solved this issue with following Code:
Java Script:
Handlebars.registerHelper('eachData', function(context, options) {
var fn = options.fn, inverse = options.inverse, ctx;
var ret = "";
if(context && context.length > 0) {
for(var i=0, j=context.length; i<j; i++) {
ctx = Object.create(context[i]);
ctx.index = i;
ret = ret + fn(ctx);
}
} else {
ret = inverse(this);
}
return ret;
});
HTML:
{{#eachData items}}
{{index}} // You got here start with 0 index
{{/eachData}}
if you want start your index with 1 you should do following code:
Javascript:
Handlebars.registerHelper('eachData', function(context, options) {
var fn = options.fn, inverse = options.inverse, ctx;
var ret = "";
if(context && context.length > 0) {
for(var i=0, j=context.length; i<j; i++) {
ctx = Object.create(context[i]);
ctx.index = i;
ret = ret + fn(ctx);
}
} else {
ret = inverse(this);
}
return ret;
});
Handlebars.registerHelper("math", function(lvalue, operator, rvalue, options) {
lvalue = parseFloat(lvalue);
rvalue = parseFloat(rvalue);
return {
"+": lvalue + rvalue
}[operator];
});
HTML:
{{#eachData items}}
{{math index "+" 1}} // You got here start with 1 index
{{/eachData}}

As it may happens that the default branch of your submodules are not master
(which happens a lot in my case), this is how I automate the full Git submodules upgrades:
git submodule init
git submodule update
git submodule foreach 'git fetch origin; git checkout $(git rev-parse --abbrev-ref HEAD); git reset --hard origin/$(git rev-parse --abbrev-ref HEAD); git submodule update --recursive; git clean -dfx'
Use the -e argument and the escape character \n:
echo -e "This will generate a next line \nThis new line is the result"
If none of the other answers on this page for you work, here's what I ran into after hours of floundering around.
I used user-specific configurations, with Sites
specified as my UserDir
in /private/etc/apache2/extra/httpd-userdir.conf
. However, I was forbidden access to the endpoint http://localhost/~jwork/
.
I could see in /var/log/apache2/error_log
that access to /Users/jwork/Sites/
was being blocked. However, I was permitted to access the DocumentRoot, via http://localhost/
. This suggested that I didn't have rights to view the ~jwork
user. But as far as I could tell by ps aux | egrep '(apache|httpd)'
and lsof -i :80
, Apache was running for the jwork
user, so something was clearly not write with my user configuration.
Given a user named jwork
, here was my config file:
/private/etc/apache2/users/jwork.conf
<Directory "/Users/jwork/Sites/">
Require all granted
</Directory>
This config is perfectly valid. However, I found that my user config wasn't being included:
/private/etc/apache2/extra/httpd-userdir.conf
## Note how it's commented out by default.
## Just remove the comment to enable your user conf.
#Include /private/etc/apache2/users/*.conf
Note that this is the default path to the userdir conf file, but as you'll see below, it's configurable in httpd.conf
. Ensure that the following lines are enabled:
/private/etc/apache2/httpd.conf
Include /private/etc/apache2/extra/httpd-userdir.conf
# ...
LoadModule userdir_module libexec/apache2/mod_userdir.so
Also be sure to check out \H, which toggles HTML output on/off. Not necessarily easy to read at the console, but interesting for dumping into a file (see \o) or pasting into an editor/browser window for viewing, especially with multiple rows of relatively complex data.
DateTime.Now.ToString("HH:mm:ss tt");
this gives it to you as a string.
I was getting this error, when I was using the same variable for json string and parsed json:
var json = '{"1":{"url":"somesite1","poster":"1.png","title":"site title"},"2":{"url":"somesite2","poster":"2.jpg","title":"site 2 title"}}'
function usingjson(){
var json = JSON.parse(json);
}
I changed function to:
function usingjson(){
var j = JSON.parse(json);
}
Now this error went away.

I had midnight issues in Word and the below code worked for me
Public Function Pause(NumberOfSeconds As Variant)
' On Error GoTo Error_GoTo
Dim PauseTime, Start
Dim objWord As Word.Document
'PauseTime = 10 ' Set duration in seconds
PauseTime = NumberOfSeconds
Start = Timer ' Set start time.
If Start + PauseTime > 86399 Then 'playing safe hence 86399
Start = 0
Do While Timer > 1
DoEvents ' Yield to other processes.
Loop
End If
Do While Timer < Start + PauseTime
DoEvents ' Yield to other processes.
Loop
End Function
Using the each syntax will prevent the entire set of keys from being generated at once. This can be important if you're using a tie-ed hash to a database with millions of rows. You don't want to generate the entire list of keys all at once and exhaust your physical memory. In this case each serves as an iterator whereas keys actually generates the entire array before the loop starts.
So, the only place "each" is of real use is when the hash is very large (compared to the memory available). That is only likely to happen when the hash itself doesn't live in memory itself unless you're programming a handheld data collection device or something with small memory.
If memory is not an issue, usually the map or keys paradigm is the more prevelant and easier to read paradigm.
This is an older question that needs a newer answer that will address @Christopher Thomas's concern above in the accept answer's comments. If you don't navigate away from the page and then select the file a second time, you need to clear the value when you click or do a touchstart(for mobile). The below will work even when you navigate away from the page and uses jquery:
//the HTML
<input type="file" id="file" name="file" />
//the JavaScript
/*resets the value to address navigating away from the page
and choosing to upload the same file */
$('#file').on('click touchstart' , function(){
$(this).val('');
});
//Trigger now when you have selected any file
$("#file").change(function(e) {
//do whatever you want here
});
