This sub will populate a Collection with all files matching the filename or pattern you pass in.
Sub GetFiles(StartFolder As String, Pattern As String, _
DoSubfolders As Boolean, ByRef colFiles As Collection)
Dim f As String, sf As String, subF As New Collection, s
If Right(StartFolder, 1) <> "\" Then StartFolder = StartFolder & "\"
f = Dir(StartFolder & Pattern)
Do While Len(f) > 0
colFiles.Add StartFolder & f
f = Dir()
Loop
If DoSubfolders then
sf = Dir(StartFolder, vbDirectory)
Do While Len(sf) > 0
If sf <> "." And sf <> ".." Then
If (GetAttr(StartFolder & sf) And vbDirectory) <> 0 Then
subF.Add StartFolder & sf
End If
End If
sf = Dir()
Loop
For Each s In subF
GetFiles CStr(s), Pattern, True, colFiles
Next s
End If
End Sub
Usage:
Dim colFiles As New Collection
GetFiles "C:\Users\Marek\Desktop\Makro\", FName & ".xls", True, colFiles
If colFiles.Count > 0 Then
'work with found files
End If
The methods Calendar.getTimeInMillis()
and Date.getTime()
both return milliseconds since 1.1.1970.
For current time, you can use:
long seconds = System.currentTimeMillis() / 1000l;
Nothing in the example says that the "classes implementing the same interface". MovieCatalog
is a type and CustomerPreferenceDao
is another type. Spring can easily tell them apart.
In Spring 2.x, wiring of beans mostly happened via bean IDs or names. This is still supported by Spring 3.x but often, you will have one instance of a bean with a certain type - most services are singletons. Creating names for those is tedious. So Spring started to support "autowire by type".
What the examples show is various ways that you can use to inject beans into fields, methods and constructors.
The XML already contains all the information that Spring needs since you have to specify the fully qualified class name in each bean. You need to be a bit careful with interfaces, though:
This autowiring will fail:
@Autowired
public void prepare( Interface1 bean1, Interface1 bean2 ) { ... }
Since Java doesn't keep the parameter names in the byte code, Spring can't distinguish between the two beans anymore. The fix is to use @Qualifier
:
@Autowired
public void prepare( @Qualifier("bean1") Interface1 bean1,
@Qualifier("bean2") Interface1 bean2 ) { ... }
In my case (after renaming application namespace manually) I had to reselect the Startup object in Project properties.
Contanis occur if using the method of the present letter, and store the corresponding number using the IndexOf method, see example below.
Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
Dim myString As String = "abcdef"
Dim numberString As String = String.Empty
If myString.Contains("d") Then
numberString = myString.IndexOf("d")
End If
End Sub
Another sample with TextBox
Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
Dim myString As String = "abcdef"
Dim numberString As String = String.Empty
If myString.Contains(me.TextBox1.Text) Then
numberString = myString.IndexOf(Me.TextBox1.Text)
End If
End Sub

package name with 0 may cause problem for sharedPreference.

To read a README.md file in the terminal I use:
pandoc README.md | lynx -stdin
Pandoc outputs it in HTML format, which Lynx renders in your terminal.
It works great: It fills my terminal, shortcuts are shown below, I can scroll through, and the links work! There is only one font size though, but the colors + indentation + alignment make up for that.
Installation:
sudo apt-get install pandoc lynx
Removing the @Slf4J annotation from the class and then re-adding it worked for me.
Since one cannot put single quotes within single quoted strings, the simplest and most readable option is to use a HEREDOC string
command=$(cat <<'COMMAND'
urxvt -fg '#111111' -bg '#111111'
COMMAND
)
alias rxvt=$command
In the code above, the HEREDOC is sent to the cat
command and the output of that is assigned to a variable via the command substitution notation $(..)
Putting a single quote around the HEREDOC is needed since it is within a $()
You may also want to look at rsync if you're doing a lot of files.
If you're going to making a lot of changes and want to keep your directories and files in sync, you may want to use a version control system like Subversion or Git. See http://xoa.petdance.com/How_to:_Keep_your_home_directory_in_Subversion
Sample Code:
ListView list = (ListView) findViewById(R.id.listview);
list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Object listItem = list.getItemAtPosition(position);
}
});
In the sample code above, the listItem
should contain the selected data for the textView
.
This might work for you:
sed 's|$ROOT|'"${HOME}"'|g' abc.sh > abc.sh.1
One needs to be somewhat careful, since the Windows batch command:
for /f "delims=" %%a in ('command') do @set theValue=%%a
does not have the same semantics as the Unix shell statement:
theValue=`command`
Consider the case where the command fails, causing an error.
In the Unix shell version, the assignment to "theValue" still occurs, any previous value being replaced with an empty value.
In the Windows batch version, it's the "for" command which handles the error, and the "do" clause is never reached -- so any previous value of "theValue" will be retained.
To get more Unix-like semantics in Windows batch script, you must ensure that assignment takes place:
set theValue=
for /f "delims=" %%a in ('command') do @set theValue=%%a
Failing to clear the variable's value when converting a Unix script to Windows batch can be a cause of subtle errors.
In case that you're using a directive like me this is how it works when you need the two data way binding for example after updating an attribute in any model or collection:
angular.module('yourApp').directive('setSurveyInEditionMode', setSurveyInEditionMode)
function setSurveyInEditionMode() {
return {
restrict: 'A',
link: function(scope, element, $attributes) {
element.on('click', function(event){
event.stopPropagation();
// In order to work with stopPropagation and two data way binding
// if you don't use scope.$apply in my case the model is not updated in the view when I click on the element that has my directive
scope.$apply(function () {
scope.mySurvey.inEditionMode = true;
console.log('inside the directive')
});
});
}
}
}
Now, you can easily use it in any button, link, div, etc. like so:
<button set-survey-in-edition-mode >Edit survey</button>
I realize this question is a bit old but here's a really simple solution that was missing. You don't need to create a custom ListView or even a custom layout.
Just create an anonymous subclass of ArrayAdapter and override getView(). Let super.getView() handle all the heavy lifting. Since simple_list_item_1 is just a text view you can customize it (e.g. set textColor) and then return it.
Here's an example from one of my apps. I'm displaying a list of recent locations and I want all occurrences of "Current Location" to be blue and the rest white.
ListView listView = (ListView) this.findViewById(R.id.listView);
listView.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, MobileMuni.getBookmarkStore().getRecentLocations()) {
@Override
public View getView(int position, View convertView, ViewGroup parent) {
TextView textView = (TextView) super.getView(position, convertView, parent);
String currentLocation = RouteFinderBookmarksActivity.this.getResources().getString(R.string.Current_Location);
int textColor = textView.getText().toString().equals(currentLocation) ? R.color.holo_blue : R.color.text_color_btn_holo_dark;
textView.setTextColor(RouteFinderBookmarksActivity.this.getResources().getColor(textColor));
return textView;
}
});
Sending a POST request is easy in vanilla Java. Starting with a URL
, we need t convert it to a URLConnection
using url.openConnection();
. After that, we need to cast it to a HttpURLConnection
, so we can access its setRequestMethod()
method to set our method. We finally say that we are going to send data over the connection.
URL url = new URL("https://www.example.com/login");
URLConnection con = url.openConnection();
HttpURLConnection http = (HttpURLConnection)con;
http.setRequestMethod("POST"); // PUT is another valid option
http.setDoOutput(true);
We then need to state what we are going to send:
A normal POST coming from a http form has a well defined format. We need to convert our input to this format:
Map<String,String> arguments = new HashMap<>();
arguments.put("username", "root");
arguments.put("password", "sjh76HSn!"); // This is a fake password obviously
StringJoiner sj = new StringJoiner("&");
for(Map.Entry<String,String> entry : arguments.entrySet())
sj.add(URLEncoder.encode(entry.getKey(), "UTF-8") + "="
+ URLEncoder.encode(entry.getValue(), "UTF-8"));
byte[] out = sj.toString().getBytes(StandardCharsets.UTF_8);
int length = out.length;
We can then attach our form contents to the http request with proper headers and send it.
http.setFixedLengthStreamingMode(length);
http.setRequestProperty("Content-Type", "application/x-www-form-urlencoded; charset=UTF-8");
http.connect();
try(OutputStream os = http.getOutputStream()) {
os.write(out);
}
// Do something with http.getInputStream()
We can also send json using java, this is also easy:
byte[] out = "{\"username\":\"root\",\"password\":\"password\"}" .getBytes(StandardCharsets.UTF_8);
int length = out.length;
http.setFixedLengthStreamingMode(length);
http.setRequestProperty("Content-Type", "application/json; charset=UTF-8");
http.connect();
try(OutputStream os = http.getOutputStream()) {
os.write(out);
}
// Do something with http.getInputStream()
Remember that different servers accept different content-types for json, see this question.
Sending files can be considered more challenging to handle as the format is more complex. We are also going to add support for sending the files as a string, since we don't want to buffer the file fully into the memory.
For this, we define some helper methods:
private void sendFile(OutputStream out, String name, InputStream in, String fileName) {
String o = "Content-Disposition: form-data; name=\"" + URLEncoder.encode(name,"UTF-8")
+ "\"; filename=\"" + URLEncoder.encode(filename,"UTF-8") + "\"\r\n\r\n";
out.write(o.getBytes(StandardCharsets.UTF_8));
byte[] buffer = new byte[2048];
for (int n = 0; n >= 0; n = in.read(buffer))
out.write(buffer, 0, n);
out.write("\r\n".getBytes(StandardCharsets.UTF_8));
}
private void sendField(OutputStream out, String name, String field) {
String o = "Content-Disposition: form-data; name=\""
+ URLEncoder.encode(name,"UTF-8") + "\"\r\n\r\n";
out.write(o.getBytes(StandardCharsets.UTF_8));
out.write(URLEncoder.encode(field,"UTF-8").getBytes(StandardCharsets.UTF_8));
out.write("\r\n".getBytes(StandardCharsets.UTF_8));
}
We can then use these methods to create a multipart post request as follows:
String boundary = UUID.randomUUID().toString();
byte[] boundaryBytes =
("--" + boundary + "\r\n").getBytes(StandardCharsets.UTF_8);
byte[] finishBoundaryBytes =
("--" + boundary + "--").getBytes(StandardCharsets.UTF_8);
http.setRequestProperty("Content-Type",
"multipart/form-data; charset=UTF-8; boundary=" + boundary);
// Enable streaming mode with default settings
http.setChunkedStreamingMode(0);
// Send our fields:
try(OutputStream out = http.getOutputStream()) {
// Send our header (thx Algoman)
out.write(boundaryBytes);
// Send our first field
sendField(out, "username", "root");
// Send a seperator
out.write(boundaryBytes);
// Send our second field
sendField(out, "password", "toor");
// Send another seperator
out.write(boundaryBytes);
// Send our file
try(InputStream file = new FileInputStream("test.txt")) {
sendFile(out, "identification", file, "text.txt");
}
// Finish the request
out.write(finishBoundaryBytes);
}
// Do something with http.getInputStream()
For fpdf to work properly, there cannot be any output at all beside what fpdf generates. For example, this will work:
<?php
$pdf = new FPDF();
$pdf->AddPage();
$pdf->SetFont('Arial','B',16);
$pdf->Cell(40,10,'Hello World!');
$pdf->Output();
?>
While this will not (note the leading space before the opening <?
tag)
<?php
$pdf = new FPDF();
$pdf->AddPage();
$pdf->SetFont('Arial','B',16);
$pdf->Cell(40,10,'Hello World!');
$pdf->Output();
?>
Also, this will not work either (the echo
will break it):
<?php
echo "About to create pdf";
$pdf = new FPDF();
$pdf->AddPage();
$pdf->SetFont('Arial','B',16);
$pdf->Cell(40,10,'Hello World!');
$pdf->Output();
?>
I'm not sure about the drupal side of things, but I know that absolutely zero non-fpdf output is a requirement for fpdf to work.
add ob_start ();
at the top and at the end add ob_end_flush();
<?php
ob_start();
require('fpdf.php');
$pdf = new FPDF();
$pdf->AddPage();
$pdf->SetFont('Arial','B',16);
$pdf->Cell(40,10,'Hello World!');
$pdf->Output();
ob_end_flush();
?>
give me an error as below:
FPDF error: Some data has already been output, can't send PDF
to over come this error:
go to fpdf.php
in that,goto line number 996
function Output($name='', $dest='')
after that make changes like this:
function Output($name='', $dest='') {
ob_clean(); //Output PDF to so
Hi do you have a session header on the top of your page. or any includes If you have then try to add this codes on top pf your page it should works fine.
<?
while (ob_get_level())
ob_end_clean();
header("Content-Encoding: None", true);
?>
cheers :-)
In my case i had set:
ini_set('display_errors', 'on');
error_reporting(E_ALL | E_STRICT);
When i made the request to generate the report, some warnings were displayed in the browser (like the usage of deprecated functions).
Turning off
the display_errors
option, the report was generated successfully.
you have an type error in example of code. You forget curlybracket after success
$.ajax({
type: "POST",
url: '@Url.Action("Search","Controller")',
data: "{queryString:'" + searchVal + "'}",
contentType: "application/json; charset=utf-8",
dataType: "html",
success: function (data) {
alert("here" + data.d.toString());
}
})
;
This worked for me:
=NOT(ISBLANK(A1))
I wanted a box around NOT Blank cells in an entire worksheet. Use the $A1 if you want the WHOLE ROW formatted based on the A1, B1, etc result.
Thanks!
I ran into this issue with custom types in stored procedures, and solved it with the script below. I didn't fully understand the scripts above, and I follow the rule of "if you don't know what it does, don't do it".
In a nutshell, I rename the old type, and create a new one with the original type name. Then, I tell SQL Server to refresh its details about each stored procedure using the custom type. You have to do this, as everything is still "compiled" with reference to the old type, even with the rename. In this case, the type I needed to change was "PrizeType". I hope this helps. I'm looking for feedback, too, so I learn :)
Note that you may need to go to Programmability > Types > [Appropriate User Type] and delete the object. I found that DROP TYPE doesn't appear to always drop the type even after using the statement.
/* Rename the UDDT you want to replace to another name */
exec sp_rename 'PrizeType', 'PrizeTypeOld', 'USERDATATYPE';
/* Add the updated UDDT with the new definition */
CREATE TYPE [dbo].[PrizeType] AS TABLE(
[Type] [nvarchar](50) NOT NULL,
[Description] [nvarchar](max) NOT NULL,
[ImageUrl] [varchar](max) NULL
);
/* We need to force stored procedures to refresh with the new type... let's take care of that. */
/* Get a cursor over a list of all the stored procedures that may use this and refresh them */
declare sprocs cursor
local static read_only forward_only
for
select specific_name from information_schema.routines where routine_type = 'PROCEDURE'
declare @sprocName varchar(max)
open sprocs
fetch next from sprocs into @sprocName
while @@fetch_status = 0
begin
print 'Updating ' + @sprocName;
exec sp_refreshsqlmodule @sprocName
fetch next from sprocs into @sprocName
end
close sprocs
deallocate sprocs
/* Drop the old type, now that everything's been re-assigned; must do this last */
drop type PrizeTypeOld;
Taken from
span() returns both start and end indexes in a single tuple. Since the match method only checks if the RE matches at the start of a string, start() will always be zero. However, the search method of RegexObject instances scans through the string, so the match may not start at zero in that case.
>>> p = re.compile('[a-z]+')
>>> print p.match('::: message')
None
>>> m = p.search('::: message') ; print m
<re.MatchObject instance at 80c9650>
>>> m.group()
'message'
>>> m.span()
(4, 11)
Combine that with:
In Python 2.2, the finditer() method is also available, returning a sequence of MatchObject instances as an iterator.
>>> p = re.compile( ... )
>>> iterator = p.finditer('12 drummers drumming, 11 ... 10 ...')
>>> iterator
<callable-iterator object at 0x401833ac>
>>> for match in iterator:
... print match.span()
...
(0, 2)
(22, 24)
(29, 31)
you should be able to do something on the order of
for match in re.finditer(r'[a-z]', 'a1b2c3d4'):
print match.span()
You can use the Django-Truncate library to delete all data of a table without destroying the table structure.
Example:
pip install django-truncate
settings.py
file:INSTALLED_APPS = [
...
'django_truncate',
]
python manage.py truncate --apps app_name --models table_name
Well there's always
assertThat(list.isEmpty(), is(false));
... but I'm guessing that's not quite what you meant :)
Alternatively:
assertThat((Collection)list, is(not(empty())));
empty()
is a static in the Matchers
class. Note the need to cast the list
to Collection
, thanks to Hamcrest 1.2's wonky generics.
The following imports can be used with hamcrest 1.3
import static org.hamcrest.Matchers.empty;
import static org.hamcrest.core.Is.is;
import static org.hamcrest.core.IsNot.*;
What SSL private key should be sent along with the client certificate?
None of them :)
One of the appealing things about client certificates is it does not do dumb things, like transmit a secret (like a password), in the plain text to a server (HTTP basic_auth
). The password is still used to unlock the key for the client certificate, its just not used directly to during exchange or tp authenticate the client.
Instead, the client chooses a temporary, random key for that session. The client then signs the temporary, random key with his cert and sends it to the server (some hand waiving). If a bad guy intercepts anything, its random so it can't be used in the future. It can't even be used for a second run of the protocol with the server because the server will select a new, random value, too.
Fails with: error:14094410:SSL routines:SSL3_READ_BYTES:sslv3 alert handshake failure
Use TLS 1.0 and above; and use Server Name Indication.
You have not provided any code, so its not clear to me how to tell you what to do. Instead, here's the OpenSSL command line to test it:
openssl s_client -connect www.example.com:443 -tls1 -servername www.example.com \
-cert mycert.pem -key mykey.pem -CAfile <certificate-authority-for-service>.pem
You can also use -CAfile
to avoid the “verify error:num=20”. See, for example, “verify error:num=20” when connecting to gateway.sandbox.push.apple.com.
Using split()
will be the most Pythonic way of splitting on a string.
It's also useful to remember that if you use split()
on a string that does not have a whitespace then that string will be returned to you in a list.
Example:
>>> "ark".split()
['ark']
Aside from what everyone has already said about HAXM and other configuration settings as solutions for this problem, my solution had nothing to do with software configuration or processor limitations.
I setup Android studio on an older HDD and I had Visual Studio running an android emulator on an SSD. My bottleneck was the old HDD - the SSD I had resulted in more speed.
The solution - albeit not the best for you - is to look in installing an SSD. This is not a very feasible solution in 90% of the cases but for me the root cause was linked to my hardware - not my software config.
Hope this helps another person facing a similar problem!
If start time is a datetime type then you can use something like
SELECT BookingId, StartTime
FROM Booking
WHERE StartTime >= '2012-03-08 00:00:00.000'
AND StartTime <= '2012-03-08 01:00:00.000'
Obviously you would want to use your own values for the times but this should give you everything in that 1 hour period inclusive of both the upper and lower limit.
You can use the GETDATE() function to get todays current date.
This is a bit of a Unix vs Linux battle. Most if not all Linux distributions have bash installed and ksh optional. Most Unix systems, like Solaris, AIX and HPUX have ksh as default.
Personally I always use ksh, I love the vi completion and I pretty much use Solaris for everything.

If the function you called returns null, it means your phone number is not registered in your contact list.
If instead of the phone number you just need an unique number, you may use the sim card's serial number:
TelephonyManager telemamanger = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
String getSimSerialNumber = telemamanger.getSimSerialNumber();
That's a very complex question for a simple answer.
You may want to take a look at existing API frameworks, like Swagger Specification (OpenAPI), and services like apiary.io and apiblueprint.org.
Also, here's an example of the same REST API described, organized and even styled in three different ways. It may be a good start for you to learn from existing common ways.
At the very top level I think quality REST API docs require at least the following:
Also there are a lot of JSON/XML-based doc frameworks which can parse your API definition or schema and generate a convenient set of docs for you. But the choice for a doc generation system depends on your project, language, development environment and many other things.
The other approach would be to allocate one contiguous chunk of memory comprising header block for pointers to rows as well as body block to store actual data in rows. Then just mark up memory by assigning addresses of memory in body to the pointers in header on per-row basis. It would look like follows:
int** 2dAlloc(int rows, int* columns) {
int header = rows * sizeof(int*);
int body = 0;
for(int i=0; i<rows; body+=columnSizes[i++]) {
}
body*=sizeof(int);
int** rowptr = (int**)malloc(header + body);
int* buf = (int*)(rowptr + rows);
rowptr[0] = buf;
int k;
for(k = 1; k < rows; ++k) {
rowptr[k] = rowptr[k-1] + columns[k-1];
}
return rowptr;
}
int main() {
// specifying column amount on per-row basis
int columns[] = {1,2,3};
int rows = sizeof(columns)/sizeof(int);
int** matrix = 2dAlloc(rows, &columns);
// using allocated array
for(int i = 0; i<rows; ++i) {
for(int j = 0; j<columns[i]; ++j) {
cout<<matrix[i][j]<<", ";
}
cout<<endl;
}
// now it is time to get rid of allocated
// memory in only one call to "free"
free matrix;
}
The advantage of this approach is elegant freeing of memory and ability to use array-like notation to access elements of the resulting 2D array.
Use -B, -A or -C option
grep --help

-B, --before-context=NUM print NUM lines of leading context
-A, --after-context=NUM print NUM lines of trailing context
-C, --context=NUM print NUM lines of output context
-NUM same as --context=NUM

Use the global method std::remove with the begin and end iterator, and then use std::vector.erase to actually remove the elements.
Documentation links
std::remove http://www.cppreference.com/cppalgorithm/remove.html
std::vector.erase http://www.cppreference.com/cppvector/erase.html
std::vector<int> v;
v.push_back(1);
v.push_back(2);
//Vector should contain the elements 1, 2
//Find new end iterator
std::vector<int>::iterator newEnd = std::remove(v.begin(), v.end(), 1);
//Erase the "removed" elements.
v.erase(newEnd, v.end());
//Vector should now only contain 2
Thanks to Jim Buck for pointing out my error.
Sorry if I answer myself, but, at the finally, the solution of my problem was update Android Studio to the new version 0.8.14 by Canary Channel: http://tools.android.com/recent/
After the update, the problem is gone:
I leave this question here for those who have this problem in the future.
You would have to tune it according to your environment.
Sometimes it's more useful to increase the size of the backlog (acceptCount) instead of the maximum number of threads.
Say, instead of
<Connector ... maxThreads="500" acceptCount="50"
you use
<Connector ... maxThreads="300" acceptCount="150"
you can get much better performance in some cases, cause there would be less threads disputing the resources and the backlog queue would be consumed faster.
In any case, though, you have to do some benchmarks to really know what is best.
You can also simply increase the Minimum memory per query value in server properties. To edit this setting, right click on server name and select Properties > Memory tab.

response = requests.post(url,data=body,headers=headers)
print response.content
Some notes:
application/soap+xml
is probably the more correct header to use (but the weatherservice prefers text/xml
For example:
from jinja2 import Environment, PackageLoader
env = Environment(loader=PackageLoader('myapp', 'templates'))
template = env.get_template('soaprequests/WeatherSericeRequest.xml')
body = template.render()
Some people have mentioned the suds library. Suds is probably the more correct way to be interacting with SOAP, but I often find that it panics a little when you have WDSLs that are badly formed (which, TBH, is more likely than not when you're dealing with an institution that still uses SOAP ;) ).
You can do the above with suds like so:
from suds.client import Client
url="http://wsf.cdyne.com/WeatherWS/Weather.asmx?WSDL"
client = Client(url)
print client ## shows the details of this service
result = client.service.GetWeatherInformation()
print result
Note: when using suds, you will almost always end up needing to use the doctor!
Finally, a little bonus for debugging SOAP; TCPdump is your friend. On Mac, you can run TCPdump like so:
sudo tcpdump -As 0
This can be helpful for inspecting the requests that actually go over the wire.
The above two code snippets are also available as gists:
another solution that works fine is to create empty list as a reference empty list.
empt_list = []
for example you have a list as a_list = [1,2,3]
. To clear it just make the following:
a_list = list(empt_list)
this will make a_list
an empty list just like the empt_list
.
File name without file extension when you don't know that extension:
$basename = substr($filename, 0, strrpos($filename, "."));
Here is a good explanation: http://carcino.gen.nz/tech/cpp/struct_vs_class.php
So, one more time: in C++, a struct is identical to a class except that the members of a struct have public visibility by default, but the members of a class have private visibility by default.
I have been having this issue with SweetAlert2 as well. SA2 differs from 1 and puts everything inside the result object. The following above can be accomplished with the following code.
Swal.fire({
title: 'A cool title',
icon: 'info',
confirmButtonText: 'Log in'
}).then((result) => {
if (result['isConfirmed']){
// Put your function here
}
})
Everything placed inside the then result will run. Result holds a couple of parameters which can be used to do the trick. Pretty simple technique. Not sure if it works the same on SweetAlert1 but I really wouldn't know why you would choose that one above the newer version.
IEnumerable
describes behavior, while List is an implementation of that behavior. When you use IEnumerable
, you give the compiler a chance to defer work until later, possibly optimizing along the way. If you use ToList() you force the compiler to reify the results right away.
Whenever I'm "stacking" LINQ expressions, I use IEnumerable
, because by only specifying the behavior I give LINQ a chance to defer evaluation and possibly optimize the program. Remember how LINQ doesn't generate the SQL to query the database until you enumerate it? Consider this:
public IEnumerable<Animals> AllSpotted()
{
return from a in Zoo.Animals
where a.coat.HasSpots == true
select a;
}
public IEnumerable<Animals> Feline(IEnumerable<Animals> sample)
{
return from a in sample
where a.race.Family == "Felidae"
select a;
}
public IEnumerable<Animals> Canine(IEnumerable<Animals> sample)
{
return from a in sample
where a.race.Family == "Canidae"
select a;
}
Now you have a method that selects an initial sample ("AllSpotted"), plus some filters. So now you can do this:
var Leopards = Feline(AllSpotted());
var Hyenas = Canine(AllSpotted());
So is it faster to use List over IEnumerable
? Only if you want to prevent a query from being executed more than once. But is it better overall? Well in the above, Leopards and Hyenas get converted into single SQL queries each, and the database only returns the rows that are relevant. But if we had returned a List from AllSpotted()
, then it may run slower because the database could return far more data than is actually needed, and we waste cycles doing the filtering in the client.
In a program, it may be better to defer converting your query to a list until the very end, so if I'm going to enumerate through Leopards and Hyenas more than once, I'd do this:
List<Animals> Leopards = Feline(AllSpotted()).ToList();
List<Animals> Hyenas = Canine(AllSpotted()).ToList();
You can fire an event yourself in ngOnInit()
of your Angular root component and then listen for this event outside of Angular.
This is Dart code (I don't know TypeScript) but should't be to hard to translate

@View(
templateUrl: 'app_element.html',
)
class AppElement implements OnInit {
ElementRef elementRef;
AppElement(this.elementRef);
void ngOnInit() {

Yes, it's true. Why do you doubt the php faq on the function? :)
The result of running password_hash()
has has four parts:
So as you can see, the hash is a part of it.
Sure, you could have an additional salt for an added layer of security, but I honestly think that's overkill in a regular php application. The default bcrypt algorithm is good, and the optional blowfish one is arguably even better.

Alex's answer shows you a solution for standard normal distribution (mean = 0, standard deviation = 1). If you have normal distribution with mean
and std
(which is sqr(var)
) and you want to calculate:
from scipy.stats import norm
# cdf(x < val)
print norm.cdf(val, m, s)
# cdf(x > val)
print 1 - norm.cdf(val, m, s)
# cdf(v1 < x < v2)
print norm.cdf(v2, m, s) - norm.cdf(v1, m, s)
Read more about cdf here and scipy implementation of normal distribution with many formulas here.
You can try this
$('div.easy_editor').css({'border-width':'9px', 'border-style':'solid', 'border-color':'red'});
The $('div.easy_editor')
refers to a collection of all divs that have the class easy editor already. There is no need to use each() unless there was some function that you wanted to run on each. The css() method actually applies to all the divs you find.
To define a auto expandable textarea, you have to do two things:
Here is a handmade function to accomplish the task.
Working fine with almost all browser ( < IE7 ). Here is the method:
//Here is an event to get TextArea expand when you press Enter Key in it.
// intiate a keypress event
$('textarea').keypress(function (e) {
if(e.which == 13) {
var control = e.target;
var controlHeight = $(control).height();
//add some height to existing height of control, I chose 17 as my line-height was 17 for the control
$(control).height(controlHeight+17);
}
});
$('textarea').blur(function (e) {
var textLines = $(this).val().trim().split(/\r*\n/).length;
$(this).val($(this).val().trim()).height(textLines*17);
});
HERE is a post about this.
There is an open source library [disclaimer: that I wrote]: LazyCache that IMO covers your requirement with two lines of code:
IAppCache cache = new CachingService();
var cachedResults = cache.GetOrAdd("CacheKey",
() => SomeHeavyAndExpensiveCalculation());
It has built in locking by default so the cacheable method will only execute once per cache miss, and it uses a lambda so you can do "get or add" in one go. It defaults to 20 minutes sliding expiration.
There's even a NuGet package ;)
It may be possible (but very hackish) with only CSS using the :before or :after pseudo elements:
.bgtext {_x000D_
position: relative;_x000D_
}_x000D_
_x000D_
.bgtext:after {_x000D_
content: "Background text";_x000D_
position: absolute;_x000D_
top: 0;_x000D_
left: 0;_x000D_
z-index: -1;_x000D_
}
_x000D_
<div class="bgtext">_x000D_
Foreground text_x000D_
</div>
_x000D_
This seems to work, but you'll probably need to tweak it a little. Also note it won't work in IE6 because it doesn't support :after
.
Another option, for incrementing the versionCode
and the versionName
, is using a timestamp.
defaultConfig {
versionName "${getVersionNameTimestamp()}"
versionCode getVersionCodeTimestamp()
}
def getVersionNameTimestamp() {
return new Date().format('yy.MM.ddHHmm')
}
def getVersionCodeTimestamp() {
def date = new Date()
def formattedDate = date.format('yyMMddHHmm')
def code = formattedDate.toInteger()
println sprintf("VersionCode: %d", code)
return code
}
Starting on January,1 2022 formattedDate = date.format('yyMMddHHmm') exceeds the capacity of Integers
I usually construct custom objects in these loops, and then add these objects to an array that I can easily manipulate, sort, export to CSV, etc.:
# Construct an out-array to use for data export
$OutArray = @()
# The computer loop you already have
foreach ($server in $serverlist)
{
# Construct an object
$myobj = "" | Select "computer", "Speed", "Regcheck"
# Fill the object
$myobj.computer = $computer
$myobj.speed = $speed
$myobj.regcheck = $regcheck
# Add the object to the out-array
$outarray += $myobj
# Wipe the object just to be sure
$myobj = $null
}
# After the loop, export the array to CSV
$outarray | export-csv "somefile.csv"
i = 20
"%x" % i #=> "14"
You're calling both wait
and notifyAll
without using a synchronized
block. In both cases the calling thread must own the lock on the monitor you call the method on.
From the docs for notify
(wait
and notifyAll
have similar documentation but refer to notify
for the fullest description):
This method should only be called by a thread that is the owner of this object's monitor. A thread becomes the owner of the object's monitor in one of three ways:
- By executing a synchronized instance method of that object.
- By executing the body of a synchronized statement that synchronizes on the object.
- For objects of type Class, by executing a synchronized static method of that class.
Only one thread at a time can own an object's monitor.
Only one thread will be able to actually exit wait
at a time after notifyAll
as they'll all have to acquire the same monitor again - but all will have been notified, so as soon as the first one then exits the synchronized block, the next will acquire the lock etc.
See a short list of python packaging tools on FreeHackers.org.
Please check which user account you use to execute our task. It may happen that you run your task with different user then your default user, and this user requires some extra privileges. Also it may happen that the task is executed but you cant see any effect because the batch file waits for some user response so please check task manager if you see your process running. Once it happen that I schedule a batch with svn update of some web page and the process hangs because svn asked for accepting server certificate.
Try to replace your initialization code with:
ProcessStartInfo info
= new ProcessStartInfo(@"C:\Program Files\Internet Explorer\iexplore.exe");
Using non full filepath on Process.Start
only works if the file is found in System32 folder.
your validation should be occur before your event suppose you are going to submit your form.
anyway if you want this on onchange, so here is code.
function valid(id)
{
var textVal=document.getElementById(id).value;
if (!textVal.match(/\S/))
{
alert("Field is blank");
return false;
}
else
{
return true;
}
}
The correct approach is to use preprocessing
For example
th:field="*{__${myVar}__}"
Tell grep
to treat your input as fixed string using -F
option.
grep -F '*^%Q&$*&^@$&*!^@$*&^&^*&^&' application.log
Option -n
is required to get the line number,
grep -Fn '*^%Q&$*&^@$&*!^@$*&^&^*&^&' application.log
I could be wrong because I've never used Angular, but I believe you are probably using ng-bind
, which will create just a TextNode.
You will want to use ng-bind-html
instead.
http://docs.angularjs.org/api/ngSanitize.directive:ngBindHtml
Update: It looks like you'll need to use ng-bind-html-unsafe='q.category'
http://docs.angularjs.org/api/ng.directive:ngBindHtmlUnsafe
Here's a demo:
Even though utf8_decode
is a useful solution, I prefer to correct the encoding errors on the table itself. In my opinion it is better to correct the bad characters themselves than making "hacks" in the code. Simply do a replace
on the field on the table. To correct the bad encoded characters from OP :
update <table> set <field> = replace(<field>, "ë", "ë")
update <table> set <field> = replace(<field>, "Ã", "à")
update <table> set <field> = replace(<field>, "ì", "ì")
update <table> set <field> = replace(<field>, "ù", "ù")
Where <table>
is the name of the mysql table and <field>
is the name of the column in the table. Here is a very good check-list for those typically bad encoded windows-1252 to utf-8 characters -> Debugging Chart Mapping Windows-1252 Characters to UTF-8 Bytes to Latin-1 Characters.
Remember to backup your table before trying to replace any characters with SQL!
[I know this is an answer to a very old question, but was facing the issue once again. Some old windows machine didnt encoded the text correct before inserting it to the utf8_general_ci collated table.]
My .replace()
function using the patterns described on the other answers did not work. The pattern that worked for my case was:
var str = "Test\n\n\Test\n\Test";
str.replace(/\r\n|\r|\n/g,' ');
// str: "Test Test Test"
Plenty of responses already, but you can use this:
Sub runQry(qDefName)
Dim db As DAO.Database, qd As QueryDef, par As Parameter
Set db = CurrentDb
Set qd = db.QueryDefs(qDefName)
On Error Resume Next
For Each par In qd.Parameters
Err.Clear
par.Value = Eval(par.Name) 'try evaluating param
If Err.Number <> 0 Then 'failed ?
par.Value = InputBox(par.Name) 'ask for value
End If
Next par
On Error GoTo 0
qd.Execute dbFailOnError
End Sub
Sub runQry_test()
runQry "test" 'qryDef name
End Sub
So I was trying to have a border appear on hover but it moved the entire bottom bar of the main menu which didn't look all that good I fixed it with the following:
#top-menu .menu-item a:hover {
border-bottom:4px solid #ec1c24;
padding-bottom:14px !important;
}
#top-menu .menu-item a {
padding-bottom:18px !important;
}
I hope this will help someone out there.
Here's my proposition:
for i in range(len(rserver.keys())):
salt = uuid.uuid4().hex
print(salt)
mdp_hash = rserver.get(rserver.keys()[i])
rserver.set(rserver.keys()[i], hashlib.sha256(salt.encode() + mdp_hash.encode()).hexdigest() + salt)
rsalt.set(rserver.keys()[i], salt)
The DataGrid has an XAML property IsReadOnly
that you can set to true
:
<my:DataGrid
IsReadOnly="True"
/>
No need for the option, just make the preferred width of the last column the maximum and it will take all the extra space.
table.getColumnModel().getColumn(0).setPreferredWidth(27);
table.getColumnModel().getColumn(1).setPreferredWidth(120);
table.getColumnModel().getColumn(2).setPreferredWidth(100);
table.getColumnModel().getColumn(3).setPreferredWidth(90);
table.getColumnModel().getColumn(4).setPreferredWidth(90);
table.getColumnModel().getColumn(6).setPreferredWidth(120);
table.getColumnModel().getColumn(7).setPreferredWidth(100);
table.getColumnModel().getColumn(8).setPreferredWidth(95);
table.getColumnModel().getColumn(9).setPreferredWidth(40);
table.getColumnModel().getColumn(10).setPreferredWidth(Integer.MAX_INT);
I usually use this parser from codeproject, since there's a bunch of character escapes and similar that it handles for me.
For a well designed system, where unit tests have driven the development from the start i would say 85% is a quite low number. Small classes designed to be testable should not be hard to cover better than that.
It's easy to dismiss this question with something like:
True, but there are some important points to be made about code coverage. In my experience this metric is actually quite useful, when used correctly. Having said that, I have not seen all systems and i'm sure there are tons of them where it's hard to see code coverage analysis adding any real value. Code can look so different and the scope of the available test framework can vary.
Also, my reasoning mainly concerns quite short test feedback loops. For the product that I'm developing the shortest feedback loop is quite flexible, covering everything from class tests to inter process signalling. Testing a deliverable sub-product typically takes 5 minutes and for such a short feedback loop it is indeed possible to use the test results (and specifically the code coverage metric that we are looking at here) to reject or accept commits in the repository.
When using the code coverage metric you should not just have a fixed (arbitrary) percentage which must be fulfilled. Doing this does not give you the real benefits of code coverage analysis in my opinion. Instead, define the following metrics:
New code can only be added if we don't go above the LWM and we don't go below the HWM. In other words, code coverage is not allowed to decrease, and new code should be covered. Notice how i say should and not must (explained below).
But doesn't this mean that it will be impossible to clean away old well-tested rubbish that you have no use for anymore? Yes, and that's why you have to be pragmatic about these things. There are situations when the rules have to be broken, but for your typical day-to-day integration my experience it that these metrics are quite useful. They give the following two implications.
Testable code is promoted. When adding new code you really have to make an effort to make the code testable, because you will have to try and cover all of it with your test cases. Testable code is usually a good thing.
Test coverage for legacy code is increasing over time. When adding new code and not being able to cover it with a test case, one can try to cover some legacy code instead to get around the LWM rule. This sometimes necessary cheating at least gives the positive side effect that the coverage of legacy code will increase over time, making the seemingly strict enforcement of these rules quite pragmatic in practice.
And again, if the feedback loop is too long it might be completely unpractical to setup something like this in the integration process.
I would also like to mention two more general benefits of the code coverage metric.
Code coverage analysis is part of the dynamic code analysis (as opposed to the static one, i.e. Lint). Problems found during the dynamic code analysis (by tools such as the purify family, http://www-03.ibm.com/software/products/en/rational-purify-family) are things like uninitialized memory reads (UMR), memory leaks, etc. These problems can only be found if the code is covered by an executed test case. The code that is the hardest to cover in a test case is usually the abnormal cases in the system, but if you want the system to fail gracefully (i.e. error trace instead of crash) you might want to put some effort into covering the abnormal cases in the dynamic code analysis as well. With just a little bit of bad luck, a UMR can lead to a segfault or worse.
People take pride in keeping 100% for new code, and people discuss testing problems with a similar passion as other implementation problems. How can this function be written in a more testable manner? How would you go about trying to cover this abnormal case, etc.
And a negative, for completeness.
You can also make use of the function Object.Freeze(). Its simple and easy:
class Singleton {
instance: any = null;
data: any = {} // store data in here
constructor() {
if (!this.instance) {
this.instance = this;
}
return this.instance
}
}
const singleton: Singleton = new Singleton();
Object.freeze(singleton);
export default singleton;
Some additional advice for Windows(10) users:
The correct way to open Jupyter notebook with new data limit from the Anaconda Prompt on my own Windows 10 PC is:
(base) C:\Users\mobarget\Google Drive\Jupyter Notebook>jupyter notebook --NotebookApp.iopub_data_rate_limit=1.0e10
Just give full path to exclusion file: eg..
-- no - - - - -xcopy c:\t1 c:\t2 /EXCLUDE:list-of-excluded-files.txt
correct - - - xcopy c:\t1 c:\t2 /EXCLUDE:C:\list-of-excluded-files.txt
In this example the file would be located " C:\list-of-excluded-files.txt "
or...
correct - - - xcopy c:\t1 c:\t2 /EXCLUDE:C:\mybatch\list-of-excluded-files.txt
In this example the file would be located " C:\mybatch\list-of-excluded-files.txt "
Full path fixes syntax error.
I agree with the current answers, but in my case it does not work, I hope this code help someone in the future:
// check
$('#checkbox_id').click()
Use :
instead of =
see the example below that gives an error
app.post('/mews', (req, res) => {
if (isValidMew(req.body)) {
// insert into db
const mew = {
name = filter.clean(req.body.name.toString()),
content = filter.clean(req.body.content.toString()),
created: new Date()
};
That gives Syntex Error: invalid shorthand proprty initializer.
Then i replace =
with :
that's solve this error.
app.post('/mews', (req, res) => {
if (isValidMew(req.body)) {
// insert into db
const mew = {
name: filter.clean(req.body.name.toString()),
content: filter.clean(req.body.content.toString()),
created: new Date()
};

IMHO, the easiest way to get audio data from a sound file into a NumPy array is SoundFile:
import soundfile as sf
data, fs = sf.read('/usr/share/sounds/ekiga/voicemail.wav')
This also supports 24-bit files out of the box.
There are many sound file libraries available, I've written an overview where you can see a few pros and cons.
It also features a page explaining how to read a 24-bit wav file with the wave
module.
You can also try this handy online tool, which generates .vssettings

$_SERVER["PHP_SELF"];
will give you the current filename and its path, but basename(__FILE__)
should give you the filename that it is called from.
So
if(basename(__FILE__) == 'file_name.php') {
//Hide
} else {
//show
}
should do it.
You have multiple ways to do this.
1:
location.href;
2:
document.URL;
3:

With the example class you posted it doesn't seem to make much sense to test getFuel()
and getSpeed()
since they can only return 0 (there are no setters).
However, assuming that this was just a simplified example for illustrative purposes, and that you have legitimate reasons to test methods in the abstract base class (others have already pointed out the implications), you could setup your test code so that it creates an anonymous subclass of the base class that just provides dummy (no-op) implementations for the abstract methods.
For example, in your TestCase
you could do this:
c = new Car() {
void drive() { };
};
Then test the rest of the methods, e.g.:
public class CarTest extends TestCase
{
private Car c;
public void setUp()
{
c = new Car() {
void drive() { };
};
}
public void testGetFuel()
{
assertEquals(c.getFuel(), 0);
}
[...]
}
(This example is based on JUnit3 syntax. For JUnit4, the code would be slightly different, but the idea is the same.)

Finally I decided to use ls, and bash array expansion:
TEMP=( $( ls -ln FILE ) )
SIZE=${TEMP[4]}
it's not really nice, but at least it does only 1 fork+execve, and it doesn't rely on secondary programming language (perl/ruby/python/whatever)
If you have a local version of the repository, you might want to try this crude shell script I wrote to open the GitHub pages for all commits matching your search term in new tabs in your default browser:
#!/bin/sh
for sha1 in $(git rev-list HEAD -i --grep="$1"); do
python -mwebbrowser https://github.com/RepoOwnerUserName/RepoName/commit/$sha1 >/dev/null 2>/dev/null
done
Just replace https://github.com/RepoOwnerUserName/RepoName/
with the actual GitHub URL of your repository, save the script somewhere (e.g. as githubsearch.sh
, make it executable (chmod +x githubsearch.sh
) and then add the following alias to your ~/.bashrc
file:
alias githubsearch='/path/to/githubsearch.sh'
Then, from anywhere in your Git repository, just do this at the terminal:
githubsearch "what you want to search for"
and any commits that match your (case insensitive) search term will have their corresponding GitHub pages opened in your browser. (Be warned that if your search term appears in hundreds of commits, this may well crash your browser and eat your PC's CPU for a while.)
While @perrejba s answer is correct, it uses the legacy C-style functions. As the question is tagged C++, you may want to use a method instead:
inputMat.copyTo(outputMat, maskMat);
All objects are of type cv::Mat
.
Please be aware that the masking is binary. Any non-zero value in the mask is interpreted as 'do copy'. Even if the mask is a greyscale image.
Also be aware that the .copyTo() function does not clear the output before copying.
If you want to permanently alter the original Image, you have to do an additional copy/clone/assignment. The copyTo() function is not defined for overlapping input/output images. So you can't use the same image as both input and output.

const iframe = '<iframe height="265" style="width: 100%;" scrolling="no" title="fx." src="//codepen.io/ycw/embed/JqwbQw/?height=265&theme-id=0&default-tab=js,result" frameborder="no" allowtransparency="true" allowfullscreen="true">See the Pen <a href="https://codepen.io/ycw/pen/JqwbQw/">fx.</a> by ycw(<a href="https://codepen.io/ycw">@ycw</a>) on <a href="https://codepen.io">CodePen</a>.</iframe>';
A function component to load Iframe
function Iframe(props) {
return (<div dangerouslySetInnerHTML={ {__html: props.iframe?props.iframe:""}} />);
}
Usage:
import React from "react";
import ReactDOM from "react-dom";
function App() {
return (
<div className="App">
<h1>Iframe Demo</h1>
<Iframe iframe={iframe} />,
</div>
);
}
const rootElement = document.getElementById("root");
ReactDOM.render(<App />, rootElement);
Edit on CodeSandbox:
Your string is wider than your format width of 2. So there's no padding to be done.
The original link I posted is now broken (there's a good reason why posting links only is not the best way to go). You have to style the RatingBar
with either ratingBarStyleSmall
or a custom style inheriting from Widget.Material.RatingBar.Small
(assuming you're using Material Design in your app).
Option 1:
<RatingBar
android:id="@+id/ratingBar"
style="?android:attr/ratingBarStyleSmall"
... />
Option 2:
// styles.xml
<style name="customRatingBar"
parent="android:style/Widget.Material.RatingBar.Small">
... // Additional customizations
</style>
// layout.xml
<RatingBar
android:id="@+id/ratingBar"
style="@style/customRatingBar"

Compared to Python, IPython (created by Fernando Perez in 2001) can do every thing what python can do. Ipython provides even extra features like tab-completion, testing, debugging, system calls and many other features. You can think IPython as a powerful interface to the Python language.
You can install Ipython using pip - pip install ipython
You can run Ipython by typing ipython
in your terminal window.
In a nutshell, "fork" creates a copy of the project hosted on your own GitHub account.
"Clone" uses git software on your computer to download the source code and it's entire version history unto that computer
Easiest solution:
plot([0,0],[0.0], xData, yData);
This creates an invisible line between the points [0,0] to [0,0] and since Matlab wants to include these points it will shows the axis.
Python does not support forward declarations, but common workaround for this is use of the the following condition at the end of your script/code:
if __name__ == '__main__': main()
With this it will read entire file first and then evaluate condition and call main() function which will be able to call any forward declared function as it already read the entire file first. This condition leverages special variable __name__
which returns __main__
value whenever we run Python code from current file (when code was imported as a module, then __name__
returns module name).
Follow this, it can be like what you are looking:
var obj = {_x000D_
Objone: 'one',_x000D_
Objtwo: 'two'_x000D_
};_x000D_
_x000D_
var key = "Objone";_x000D_
delete obj[key];_x000D_
console.log(obj); // prints { "objtwo": two}
_x000D_
This is a more user-friendly one I guess :
#include<stdio.h>
/* This program checks if the entered input is an integer
* or provides an option for the user to re-enter.
*/
int getint()
{
int x;
char c;
printf("\nEnter an integer (say -1 or 26 or so ): ");
while( scanf("%d",&x) != 1 )
{
c=getchar();
printf("You have entered ");
putchar(c);
printf(" in the input which is not an integer");
while ( getchar() != '\n' )
; //wasting the buffer till the next new line
printf("\nEnter an integer (say -1 or 26 or so ): ");
}
return x;
}
int main(void)
{
int x;
x=getint();
printf("Main Function =>\n");
printf("Integer : %d\n",x);
return 0;
}
You have VisualTkinter also known as Visual Python. Development seems not active. You have sourceforge and googlecode sites. Web site is here.
On the other hand, you have PAGE that seems active and works in python 2.7 and py3k
As you indicate on your comment, none of these use the grid
geometry. As far as I can say the only GUI builder doing that could probably be Komodo Pro GUI Builder which was discontinued and made open source in ca. 2007. The code was located in the SpecTcl repository.
It seems to install fine on win7 although has not used it yet. This is an screenshot from my PC:
By the way, Rapyd Tk also had plans to implement grid geometry as in its documentation says it is not ready 'yet'. Unfortunately it seems 'nearly' abandoned.
not need to run queries to sidable FKs on sql. If you have a FK from table A to B, you should:
You can also tell the destination not to check constraints
If you want to add a sourceSet for testing in addition to all the existing ones, within a module regardless of the active flavor:
sourceSets {
test {
java.srcDirs += [
'src/customDir/test/kotlin'
]
print(java.srcDirs) // Clean
}
}
Pay attention to the operator +=
and if you want to run integration tests change test
to androidTest
.

since PHP 5.4 you can use http_response_code()
for get and set header status code.
here an example:
<?php
// Get the current response code and set a new one
var_dump(http_response_code(404));
// Get the new response code
var_dump(http_response_code());
?>
here is the document of this function in php.net:
I seem to recall having to use @GeneratedValue(strategy = GenerationType.IDENTITY)
to get Hibernate to use 'serial' columns on PostgreSQL.
I use filter
.filter('toDate', function() {
return function(items) {
return new Date(items);
};
});
then
{{'2018-05-06 09:04:13' | toDate | date:'dd/MM/yyyy hh:mm'}}
As described in the answer of Ricardo ,
netsh Winsock reset
has worked for me ,
P.S. if you have Internet download manager or such programs which changes you IP Setting is installed then after running this command when you reboot your computer IDM will ask to change setting , Set NO in this case and then run your application it will work correctly.
Hope it
I might misunderstand, but are you trying to delete files newly ignored or do you want to ignore new modifications to these files ? In this case, the thing is working.
If you want to delete ignored files previously commited, then use
git rm –cached `git ls-files -i –exclude-standard`
git commit -m 'clean up'
A really common way to see a clear example of the use of the three dots it is present in one of the most famous methods in android AsyncTask ( that today is not used too much because of RXJAVA, not to mention the Google Architecture components), you can find thousands of examples searching for this term, and the best way to understand and never forget anymore the meaning of the three dots is that they express a ...doubt... just like in the common language. Namely it is not clear the number of parameters that have to be passed, could be 0, could be 1 could be more( an array)...
There is a chrome extension available in the chrome web store named Clear Cache.
I use it every day and its a very useful tool I think. You can use it as a reload button and can clear the cache and if you like also cookies, locale storage, form data etc. Also you can define on which domain this happens. So can clear all this shit with only the reload button which you anyway have to press - on your chosen domains.
Very very nice!
You also can define a Keyboard Shortcut for this in the options!
Also another way is to start your chrome window in incognito-mode. Here the cache also should be completely disabled.
You are unable to return NULL
because the return type of the function is an object reference
and not a pointer
.
If you want to add a single column after a specific field, then the following MySQL query should work:
ALTER TABLE users
ADD COLUMN count SMALLINT(6) NOT NULL
AFTER lastname
If you want to add multiple columns, then you need to use 'ADD' command each time for a column. Here is the MySQL query for this:
ALTER TABLE users
ADD COLUMN count SMALLINT(6) NOT NULL,
ADD COLUMN log VARCHAR(12) NOT NULL,
ADD COLUMN status INT(10) UNSIGNED NOT NULL
AFTER lastname
In the second method, the last ADD COLUMN
column should actually be the first column you want to append to the table.
E.g: if you want to add count
, log
, status
in the exact order after lastname
, then the syntax would actually be:
ALTER TABLE users
ADD COLUMN log VARCHAR(12) NOT NULL AFTER lastname,
ADD COLUMN status INT(10) UNSIGNED NOT NULL AFTER lastname,
ADD COLUMN count SMALLINT(6) NOT NULL AFTER lastname
It depends on the context.
When it's within a class:
class example1 {
int a = 10; // This is package-private (visible within package)
void method1() // This is package-private as well.
{
-----
}
}
When it's within a interface:
interface example2 {
int b = 10; // This is public and static.
void method2(); // This is public and abstract
}
My original suggestion was
s12 := fmt.Sprint(s1,s2)
But above answer using bytes.Buffer - WriteString() is the most efficient way.
My initial suggestion uses reflection and a type switch. See (p *pp) doPrint
and (p *pp) printArg
There is no universal Stringer() interface for basic types, as I had naively thought.
At least though, Sprint() internally uses a bytes.Buffer. Thus
`s12 := fmt.Sprint(s1,s2,s3,s4,...,s1000)`
is acceptable in terms of memory allocations.
=> Sprint() concatenation can be used for quick debug output.
=> Otherwise use bytes.Buffer ... WriteString
You want reorder()
. Here is an example with dummy data
set.seed(42)
df <- data.frame(Category = sample(LETTERS), Count = rpois(26, 6))
require("ggplot2")
p1 <- ggplot(df, aes(x = Category, y = Count)) +
geom_bar(stat = "identity")
p2 <- ggplot(df, aes(x = reorder(Category, -Count), y = Count)) +
geom_bar(stat = "identity")
require("gridExtra")
grid.arrange(arrangeGrob(p1, p2))
Giving:
Use reorder(Category, Count)
to have Category
ordered from low-high.
add a new .css class:
#test.nohover:hover { border: 0 }
and
<div id="test" class="nohover">blah</div>
The more "specific" css rule wins, so this border:0 version will override the generic one specified elsewhere.
Are you looking for the string contains a certain number of words or contains specific words? Your example leads towards the latter.
In that case, you may wish to look into parsing strings or at least use regex.
Learn regex - it will be useful 1000x over in programming. I cannot emphasize this too much. Using contains and if statements will turn into a mess very quickly.
If you are just trying to count words, then :
string d = "You hit someone for 50 damage";
string[] words = d.Split(' '); // Break up the string into words
Console.Write(words.Length);
This is the Method to get contact list Name and Number

if (cursor.getCount() > 0) {
while (cursor.moveToNext()) {
int hasPhoneNumber = Integer.parseInt(cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER)));
if (hasPhoneNumber > 0) {
String id = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
String name = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
Cursor phoneCursor = contentResolver.query(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI,

if (phoneCursor.moveToNext()) {
String phoneNumber = phoneCursor.getString(phoneCursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
//At here You can add phoneNUmber and Name to you listView ,ModelClass,Recyclerview
phoneCursor.close();
}
}
}

}
}
In order to use gets
safely, you have to know exactly how many characters you will be reading, so that you can make your buffer large enough. You will only know that if you know exactly what data you will be reading.
Instead of using gets
, you want to use fgets
, which has the signature
char* fgets(char *string, int length, FILE * stream);
(fgets
, if it reads an entire line, will leave the '\n'
in the string; you'll have to deal with that.)
It remained an official part of the language up to the 1999 ISO C standard, but it was officially removed by the 2011 standard. Most C implementations still support it, but at least gcc issues a warning for any code that uses it.
I don't see any documentation that says the order in app.xml is guaranteed to be the order of the sheets. It PROBABLY is, but not according to the OOXML specification.
The workbook.xml file, on the other hand, includes the sheetId attribute, which does determine the sequence - from 1 to the number of sheets. This is according to the OOXML specification. workbook.xml is described as the place where the sequence of the sheets is kept.
So reading workbook.xml after it is extracted form the XLSX would be my recommendation. NOT app.xml. Instead of docProps/app.xml, use xl/workbook.xml and look at the element, as shown here -
`
<workbook xmlns="http://schemas.openxmlformats.org/spreadsheetml/2006/main" xmlns:r="http://schemas.openxmlformats.org/officeDocument/2006/relationships">

git apply --reverse --reject example.patch
When you created a patch file with the branch names reversed:
ie. git diff feature_branch..master
instead of git diff master..feature_branch
If you want to keep your \t
equal to 8 spaces then consider setting:
set softtabstop=2 tabstop=8 shiftwidth=2
This will give you two spaces per <TAB>
press, but actual \t
in your code will still be viewed as 8 characters.
In Rails 2, I would have written:
validates_uniqueness_of :zipcode, :scope => :recorded_at
In Rails 3:
validates :zipcode, :uniqueness => {:scope => :recorded_at}
For multiple attributes:
validates :zipcode, :uniqueness => {:scope => [:recorded_at, :something_else]}
You (still) can not choose the position of the column using ALTER TABLE: it can only be added to the end of the table. You can obviously select the columns in any order you want, so unless you are using SELECT * FROM column order shouldn't be a big deal.
If you really must have them in a particular order and you can't drop and recreate the table, then you might be able to drop and recreate columns instead:-
First copy the table
CREATE TABLE my_tab_temp AS SELECT * FROM my_tab;
Then drop columns that you want to be after the column you will insert
ALTER TABLE my_tab DROP COLUMN three;
Now add the new column (two in this example) and the ones you removed.
ALTER TABLE my_tab ADD (two NUMBER(2), three NUMBER(10));
Lastly add back the data for the re-created columns
UPDATE my_tab SET my_tab.three = (SELECT my_tab_temp.three FROM my_tab_temp WHERE my_tab.one = my_tab_temp.one);
Obviously your update will most likely be more complex and you'll have to handle indexes and constraints and won't be able to use this in some cases (LOB columns etc). Plus this is a pretty hideous way to do this - but the table will always exist and you'll end up with the columns in a order you want. But does column order really matter that much?
You should use #!/usr/bin/env bash
for portability: different *nixes put bash
in different places, and using /usr/bin/env
is a workaround to run the first bash
found on the PATH
. And sh
is not bash

If you are on Mac OSX,
The default location for the MySQL Unix socket is different on Mac OS X and Mac OS X Server depending on the installation type you chose
MySQL Unix Socket Locations on Mac OS X by Installation Type
So just change your database.yml in socket: /tmp/mysql.sock

just add static keyword at the starting of the function return type.. and then you can access the member function of the class without object:) for ex:
static void Name_pairs::read_names()

cout << "Enter name: ";
cin >> name;
names.push_back(name);
cout << endl;
}

right click on the project and select Manage NuGet Packages..

what is your purpose of disabling the right click. problem with any technique is that there is always a way to go around them. the console for firefox (firebug) and chrome allow for unbinding of that event. or if you want the image to be protected one could always just take a look at their temporary cache for the images.
If you want to create your own contextual menu the preventDefault is fine. Just pick your battles here. not even a big JavaScript library like tnyMCE works on all browsers... and that is not because it's not possible ;-).
$(document).bind("contextmenu",function(e){
e.preventDefault()
});
Personally I'm more in for an open internet. Native browser behavior should not be hindered by the pages interactions. I am sure that other ways can be found to interact that are not the right click.
if var == 'stringone' or var == 'stringtwo':
dosomething()
'is' is used to check if the two references are referred to a same object. It compare the memory address. Apparently, 'stringone' and 'var' are different objects, they just contains the same string, but they are two different instances of the class 'str'. So they of course has two different memory addresses, and the 'is' will return False.
Just read this great .Net DI container comparison blog by Philip Mat.
He does some thorough performance comparison tests on;
He recommends Autofac as it is small, fast, and easy to use ... I agree. It appears that Unity and Ninject are the slowest in his tests.
Just run composer install
- it will make your vendor
directory reflect dependencies in composer.lock

In other words - it will delete any vendor which is missing in composer.lock

Please update the composer itself before running this.
For this you can simply use the "HttpWebRequest" and "HttpWebResponse" classes in .net.
Below is a sample console app I wrote to demonstrate how easy this is.
using System;
using System.Collections.Generic;
using System.Text;
using System.Net;
using System.IO;
namespace Test
{
class Program
{
static void Main(string[] args)
{
string url = "www.somewhere.com";
string fileName = @"C:\output.file";
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
request.Timeout = 5000;
try
{
using (WebResponse response = (HttpWebResponse)request.GetResponse())
{
using (FileStream stream = new FileStream(fileName, FileMode.Create, FileAccess.Write))
{
byte[] bytes = ReadFully(response.GetResponseStream());
stream.Write(bytes, 0, bytes.Length);
}
}
}
catch (WebException)
{
Console.WriteLine("Error Occured");
}
}
public static byte[] ReadFully(Stream input)
{
byte[] buffer = new byte[16 * 1024];
using (MemoryStream ms = new MemoryStream())
{
int read;
while ((read = input.Read(buffer, 0, buffer.Length)) > 0)
{
ms.Write(buffer, 0, read);
}
return ms.ToArray();
}
}
}
}

Use the modern version of the Fisher–Yates shuffle algorithm:
/**
* Shuffles array in place.
* @param {Array} a items An array containing the items.
*/
function shuffle(a) {
var j, x, i;
for (i = a.length - 1; i > 0; i--) {
j = Math.floor(Math.random() * (i + 1));
x = a[i];
a[i] = a[j];
a[j] = x;
}
return a;
}
/**
* Shuffles array in place. ES6 version
* @param {Array} a items An array containing the items.
*/
function shuffle(a) {
for (let i = a.length - 1; i > 0; i--) {
const j = Math.floor(Math.random() * (i + 1));
[a[i], a[j]] = [a[j], a[i]];
}
return a;
}
Note however, that swapping variables with destructuring assignment causes significant performance loss, as of October 2017.
var myArray = ['1','2','3','4','5','6','7','8','9'];
shuffle(myArray);
Using Object.defineProperty
(method taken from this SO answer) we can also implement this function as a prototype method for arrays, without having it show up in loops such as for (i in arr)
. The following will allow you to call arr.shuffle()
to shuffle the array arr
:
Object.defineProperty(Array.prototype, 'shuffle', {
value: function() {
for (let i = this.length - 1; i > 0; i--) {
const j = Math.floor(Math.random() * (i + 1));
[this[i], this[j]] = [this[j], this[i]];
}
return this;
}
});
What you want is:
cp -R t1/. t2/
The dot at the end tells it to copy the contents of the current directory, not the directory itself. This method also includes hidden files and folders.
Another answer I would have for this would be to take a pragmatic approach and keep your REST API contract simple. In my case I had refactored my REST API to make things more testable without resorting to JavaScript or XHR, just simple HTML forms and links.
So to be more specific on your question above, I'd just use return code 200
and have the returned message contain a JSON message that your application can understand. Depending on your needs it may require the ID of the object that is newly created so the web application can get the data in another call.
One note, in my refactored API contract, POST responses should not contain any cacheable data as POSTs are not really cachable, so limit it to IDs that can be requested and cached using a GET request.
The above solutions work if you are compressing all white space in the XML document. Other quick options are JDOM (using Format.getCompactFormat()) and dom4j (using OutputFormat.createCompactFormat()) when outputting the XML document.
However, I had a unique requirement to preserve the white space contained within the element's text value and these solutions did not work as I needed. All I needed was to remove the 'pretty-print' formatting added to the XML document.
The solution that I came up with can be explained in the following 3-step/regex process ... for the sake of understanding the algorithm for the solution.
String regex, updatedXml;
// 1. remove all white space preceding a begin element tag:
regex = "[\\n\\s]+(\\<[^/])";
updatedXml = originalXmlStr.replaceAll( regex, "$1" );
// 2. remove all white space following an end element tag:
regex = "(\\</[a-zA-Z0-9-_\\.:]+\\>)[\\s]+";
updatedXml = updatedXml.replaceAll( regex, "$1" );
// 3. remove all white space following an empty element tag
// (<some-element xmlns:attr1="some-value".... />):
regex = "(/\\>)[\\s]+";
updatedXml = updatedXml.replaceAll( regex, "$1" );
NOTE: The pseudo-code is in Java ... the '$1' is the replacement string which is the 1st capture group.
This will simply remove the white space used when adding the 'pretty-print' format to an XML document, yet preserve all other white space when it is part of the element text value.

Based on the solution by Jason Bunting, here is what I use now.
The whole thing is for the jQuery tablesorter plug-in: For (nearly correct) sorting of non-English tables with tablesorter plugin it is necessary to make use of a custom textExtraction

return text.replace(patternLetters, letterTranslator);
}
})();
}
You can use it like this:
$("table.sortable").tablesorter({
textExtraction: getTextExtractor()
});
Do a SELECT COUNT(*) FROM ...
query instead.
OR
int size =0;
if (rs != null)
{
rs.last(); // moves cursor to the last row
size = rs.getRow(); // get row id
}
In either of the case, you won't have to loop over the entire data.
It's easy. If you have two or more running container, complete next steps:
docker network create myNetwork
docker network connect myNetwork web1
docker network connect myNetwork web2
Now you connect from web1 to web2 container or the other way round.
Use the internal network IP addresses which you can find by running:
docker network inspect myNetwork
Note that only internal IP addresses and ports are accessible to the containers connected by the network bridge.
So for example assuming that web1 container was started with: docker run -p 80:8888 web1
(meaning that its server is running on port 8888 internally), and inspecting myNetwork
shows that web1's IP is 172.0.0.2, you can connect from web2 to web1 using curl 172.0.0.2:8888
).
echo $_SERVER['REMOTE_ADDR'];
Interesting to note, all sources emphasize that @Column(nullable=false) is used only for DDL generation.
However, even if there is no @NotNull annotation, and hibernate.check_nullability option is set to true, Hibernate will perform validation of entities to be persisted.
It will throw PropertyValueException saying that "not-null property references a null or transient value", if nullable=false attributes do not have values, even if such restrictions are not implemented in the database layer.
More information about hibernate.check_nullability option is available here: http://docs.jboss.org/hibernate/orm/5.0/userguide/html_single/Hibernate_User_Guide.html#configurations-mapping.
Using a null reference as the first operand to instanceof

Some time your $watch is calling dynamically
and it will create its instances so you have to call deregistration function before your $watch
function
if(myWatchFun)
myWatchFun(); // it will destroy your previous $watch if any exist
myWatchFun = $scope.$watch("abc", function () {});
you can use this subclass of tableView:
import UIKit
protocol PullToRefreshTableViewDelegate : class {
func tableViewDidStartRefreshing(tableView: PullToRefreshTableView)
}
class PullToRefreshTableView: UITableView {
@IBOutlet weak var pullToRefreshDelegate: AnyObject?
private var refreshControl: UIRefreshControl!
private var isFirstLoad = true
override func willMoveToSuperview(newSuperview: UIView?) {
super.willMoveToSuperview(newSuperview)
if (isFirstLoad) {
addRefreshControl()
isFirstLoad = false
}
}
private func addRefreshControl() {
refreshControl = UIRefreshControl()
refreshControl.attributedTitle = NSAttributedString(string: "Pull to refresh")
refreshControl.addTarget(self, action: "refresh", forControlEvents: .ValueChanged)
self.addSubview(refreshControl)
}
@objc private func refresh() {
(pullToRefreshDelegate as? PullToRefreshTableViewDelegate)?.tableViewDidStartRefreshing(self)
}
func endRefreshing() {
refreshControl.endRefreshing()
}
}
1 - in interface builder change the class of your tableView to PullToRefreshTableView
or create a PullToRefreshTableView
programmatically
2 - implement the PullToRefreshTableViewDelegate
in your view controller
3 - tableViewDidStartRefreshing(tableView: PullToRefreshTableView)
will be called in your view controller when the table view starts refreshing
4 - call yourTableView.endRefreshing()
to finish the refreshing
UTF-8 is prepared for world domination, Latin1 isn't.
If you're trying to store non-Latin characters like Chinese, Japanese, Hebrew, Russian, etc using Latin1 encoding, then they will end up as mojibake. You may find the introductory text of this article useful (and even more if you know a bit Java).
Note that full 4-byte UTF-8 support was only introduced in MySQL 5.5. Before that version, it only goes up to 3 bytes per character, not 4 bytes per character. So, it supported only the BMP plane and not e.g. the Emoji plane. If you want full 4-byte UTF-8 support, upgrade MySQL to at least 5.5 or go for another RDBMS like PostgreSQL. In MySQL 5.5+ it's called utf8mb4
.
I would try to avoid changing the xticklabels
if possible, otherwise it can get very confusing if you for example overplot your histogram with additional data.
Defining the range of your grid is probably the best and with imshow
it can be done by adding the extent
keyword. This way the axes gets adjusted automatically. If you want to change the labels i would use set_xticks
with perhaps some formatter. Altering the labels directly should be the last resort.
fig, ax = plt.subplots(figsize=(6,6))
ax.imshow(hist, cmap=plt.cm.Reds, interpolation='none', extent=[80,120,32,0])
ax.set_aspect(2) # you may also use am.imshow(..., aspect="auto") to restore the aspect ratio

This is something that worked for me, although it smells a bit wrong:
var iframe = ...
var doc = iframe.contentDocument;
var i = doc.createElement('input');
i.style.display = 'none';
doc.body.appendChild(i);
i.focus();
doc.body.removeChild(i);
hmmm. it also scrolls to the bottom of the content. Guess I should be inserting the dummy textbox at the top.
2019 SOLUTION: You can use position: sticky
property.
Here is an example CODEPEN demonstrating the usage and also how it differs from position: fixed
.
How it behaves is explained below:
An element with sticky position is positioned based on the user's scroll position. It basically acts like position: relative
until an element is scrolled beyond a specific offset, in which case it turns into position: fixed. When it is scrolled back it gets back to its previous (relative) position.
It effects the flow of other elements in the page ie occupies a specific space on the page(just like position: relative
).
If it is defined inside some container, it is positioned with respect to that container. If the container has some overflow(scroll), depending on the scroll offset it turns into position:fixed.
So if you want to achieve the fixed functionality but inside a container, use sticky.
A simple js can solve this:
document.getElementById("idName").style.background = "blue";
An AsyncTask
is used to do some background computation and publish the result to the UI thread (with optional progress updates). Since you're not concerned with UI, then a Handler
or Thread
seems more appropriate.
You can spawn a background Thread
and pass messages back to your main thread by using the Handler
's post
method.
The thing on the right of <-
is a formula
object. It is often used to denote a statistical model, where the thing on the left of the ~
is the response and the things on the right of the ~
are the explanatory variables. So in English you'd say something like "Species depends on Sepal Length, Sepal Width, Petal Length and Petal Width".
The myFormula <-
part of that line stores the formula in an object called myFormula
so you can use it in other parts of your R code.
Other common uses of formula objects in R
The lattice
package uses them to specify the variables to plot.
The ggplot2
package uses them to specify panels for plotting.
The dplyr
package uses them for non-standard evaulation.
If your not overly worried about the size of the file then it may be easier for you to store the data as a JS object in another file and import it in your . Either synchronously or asynchronously using the syntax <script src="countries.js" async></script>
. Saves on you needing to import the file and parse it.
However, i can see why you wouldnt want to rewrite 10000 entries so here's a basic object orientated csv parser i wrote.
function requestCSV(f,c){return new CSVAJAX(f,c);};
function CSVAJAX(filepath,callback)
{
this.request = new XMLHttpRequest();
this.request.timeout = 10000;
this.request.open("GET", filepath, true);
this.request.parent = this;
this.callback = callback;
this.request.onload = function()
{
var d = this.response.split('\n'); /*1st separator*/
var i = d.length;
while(i--)
{
if(d[i] !== "")
d[i] = d[i].split(','); /*2nd separator*/
else
d.splice(i,1);
}
this.parent.response = d;
if(typeof this.parent.callback !== "undefined")
this.parent.callback(d);
};
this.request.send();
};
Which can be used like this;
var foo = requestCSV("csvfile.csv",drawlines(lines));
The first parameter is the file, relative to the position of your html file in this case. The second parameter is an optional callback function the runs when the file has been completely loaded.
If your file has non-separating commmas then it wont get on with this, as it just creates 2d arrays by chopping at returns and commas. You might want to look into regexp if you need that functionality.
//THIS works
"1234","ABCD" \n
"!@£$" \n
//Gives you
[
[
1234,
'ABCD'
],
[
'!@£$'
]
]
//This DOESN'T!
"12,34","AB,CD" \n
"!@,£$" \n
//Gives you
[
[
'"12',
'34"',
'"AB',
'CD'
]
[
'"!@',
'£$'
]
]
If your not used to the OO methods; they create a new object (like a number, string, array) with their own local functions and variables via a 'constructor' function. Very handy in certain situations. This function could be used to load 10 different files with different callbacks all at the same time(depending on your level of csv love! )
For creating session only cookie with java script, you can use the following. This works for me.
document.cookie = "cookiename=value; expires=0; path=/";
then get cookie value as following
//get cookie
var cookiename = getCookie("cookiename");
if (cookiename == "value") {
//write your script
}
//function getCookie
function getCookie(cname) {
var name = cname + "=";
var ca = document.cookie.split(';');
for (var i = 0; i < ca.length; i++) {
var c = ca[i];
while (c.charAt(0) == ' ') c = c.substring(1);
if (c.indexOf(name) != -1) return c.substring(name.length, c.length);
}
return "";
}
Okay to support IE we can leave "expires" completely and can use this
document.cookie = "mtracker=somevalue; path=/";
You'll need two slightly different conversions.
To convert from Time
to DateTime
you can amend the Time class as follows:
require 'date'
class Time
def to_datetime
# Convert seconds + microseconds into a fractional number of seconds
seconds = sec + Rational(usec, 10**6)
# Convert a UTC offset measured in minutes to one measured in a
# fraction of a day.
offset = Rational(utc_offset, 60 * 60 * 24)
DateTime.new(year, month, day, hour, min, seconds, offset)
end
end
Similar adjustments to Date will let you convert DateTime
to Time
.
class Date
def to_gm_time
to_time(new_offset, :gm)
end
def to_local_time
to_time(new_offset(DateTime.now.offset-offset), :local)
end
private
def to_time(dest, method)
#Convert a fraction of a day to a number of microseconds
usec = (dest.sec_fraction * 60 * 60 * 24 * (10**6)).to_i
Time.send(method, dest.year, dest.month, dest.day, dest.hour, dest.min,
dest.sec, usec)
end
end
Note that you have to choose between local time and GM/UTC time.

I am working on a multi-module Gradle project.
Modules are:
- core,
- service,
- geo,
- report,
- util and
- some other modules.
So primarily we have prepared a Component[locationRecommendHttpClientBuilder] in geo module.
import org.springframework.stereotype.Component
@Component("locationRecommendHttpClientBuilder")
class LocationRecommendHttpClientBuilder extends PanaromaHttpClientBuilder {
@Override
PanaromaHttpClient buildFromConfiguration() {
this.setURL(PanaromaConf.getInstance().getString("locationrecommend.url"))
this.setMethod(PanaromaConf.getInstance().getString("locationrecommend.method"))
this.setProxyHost(PanaromaConf.getInstance().getString("locationrecommend.proxy.host"))
this.setProxyPort(PanaromaConf.getInstance().getInt("locationrecommend.proxy.port", 0))
return super.build()
}
}
<bean id="locationRecommendHttpClient"
class="au.co.google.panaroma.platform.logic.impl.PanaromaHttpClient"
scope="singleton" factory-bean="locationRecommendHttpClientBuilder"
factory-method="buildFromConfiguration" />
Then it is decided to add this component in core module.
One engineer has previous code for geo module and then he has taken the latest module of core but he forgot to take the latest geo module.
So the component[locationRecommendHttpClientBuilder] is double times in his project and he was getting the following error.
Caused by: org.springframework.context.annotation.ConflictingBeanDefinitionException: Annotation-specified bean name 'LocationRecommendHttpClientBuilder' for bean class [au.co.google.app.locationrecommendation.builder.LocationRecommendHttpClientBuilder] conflicts with existing, non-compatible bean definition of same name and class [au.co.google.panaroma.platform.logic.impl.locationRecommendHttpClientBuilder]
After removal the component from geo module, component[locationRecommendHttpClientBuilder] is only available in core module. So there is no conflicting situation. Issue is solved by this way.
SOLUTION 1 - simple and effective
$file_name = preg_replace( '/[^a-z0-9]+/', '-', strtolower( $url ) );
[^a-z0-9]+
will ensure, the filename only keeps letters and numbers'-'
keeps the filename readableExample:
URL: http://stackoverflow.com/questions/2021624/string-sanitizer-for-filename
File: http-stackoverflow-com-questions-2021624-string-sanitizer-for-filename
SOLUTION 2 - for very long URLs
You want to cache the URL contents and just need to have unique filenames. I would use this function:
$file_name = md5( strtolower( $url ) )
this will create a filename with fixed length. The MD5 hash is in most cases unique enough for this kind of usage.
Example:
URL: https://www.amazon.com/Interstellar-Matthew-McConaughey/dp/B00TU9UFTS/ref=s9_nwrsa_gw_g318_i10_r?_encoding=UTF8&fpl=fresh&pf_rd_m=ATVPDKIKX0DER&pf_rd_s=desktop-1&pf_rd_r=BS5M1H560SMAR2JDKYX3&pf_rd_r=BS5M1H560SMAR2JDKYX3&pf_rd_t=36701&pf_rd_p=6822bacc-d4f0-466d-83a8-2c5e1d703f8e&pf_rd_p=6822bacc-d4f0-466d-83a8-2c5e1d703f8e&pf_rd_i=desktop

string input = "America.USA"
string output = input.Substring(input.IndexOf('.') + 1);
This works too and you dont have to use join or anything:
DROP VIEW IF EXISTS yourview;
CREATE VIEW yourview AS
SELECT table1.column1,
table2.column2
FROM
table1, table2
WHERE table1.column1 = table2.column1;
This is a simple example of what I used for a recent test. You need to make sure that your security settings are the same on the server and client.
var myBinding = new BasicHttpBinding();
myBinding.Security.Mode = BasicHttpSecurityMode.None;
var myEndpointAddress = new EndpointAddress("http://servername:8732/TestService/");
client = new ClientTest(myBinding, myEndpointAddress);
client.someCall();
None of the other answers helped me. Here's what worked for me. I'm using the tutorial-1 sample from opencv but I will be doing using the NDK in my project so I'm using the gradle-experimental plugin which has a different structure than the gradle plugin.
Android studio should be installed, the Android NDK should be installed via the Android SDK Manager, and the OpenCV Android SDK should be downloaded and unzipped.
This is in chunks of bash script to keep it compact but complete. It's also all on the command line because on of the big problems I had was that in-IDE instructions were obsolete as the IDE evolved.
First set the location of the root directory of the OpenCV SDK.
export OPENCV_SDK=/home/user/wip/OpenCV-2.4.11-android-sdk
cd $OPENCV_SDK
Create your gradle build files...
First the OpenCV library
cat > $OPENCV_SDK/sdk/java/build.gradle <<'==='
apply plugin: 'com.android.model.library'
model {
android {
compileSdkVersion = 23
buildToolsVersion = "23.0.2"
defaultConfig.with {
minSdkVersion.apiLevel = 8
targetSdkVersion.apiLevel = 23
}
}
android.buildTypes {
release {
minifyEnabled = false
}
debug{
minifyEnabled = false
}
}
android.sources {
main.manifest.source.srcDirs += "."
main.res.source.srcDirs += "res"
main.aidl.source.srcDirs += "src"
main.java.source.srcDirs += "src"
}
}
===
Then tell the tutorial sample what to label the library as and where to find it.
cat > $OPENCV_SDK/samples/tutorial-1-camerapreview/settings.gradle <<'==='
include ':openCVLibrary2411'
project(':openCVLibrary2411').projectDir = new File('../../sdk/java')
===
Create the build file for the tutorial.
cat > $OPENCV_SDK/samples/tutorial-1-camerapreview/build.gradle <<'==='
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle-experimental:0.2.1'
}

}
}
apply plugin: 'com.android.model.application'
model {
android {
compileSdkVersion = 23
buildToolsVersion = "23.0.2"
defaultConfig.with {
applicationId = "org.opencv.samples.tutorial1"

}
android.buildTypes {
release {
minifyEnabled = false
proguardFiles += file('proguard-rules.pro')
}
debug {
minifyEnabled = false
}
}
}
dependencies {
compile project(':openCVLibrary2411')
}
===
Your build tools version needs to be set correctly. Here's an easy way to see what you have installed. (You can install other versions via the Android SDK Manager). Change buildToolsVersion if you don't have 23.0.2.
echo "Your buildToolsVersion is one of: "
ls $ANDROID_HOME/build-tools
Change the environment variable on the first line to your version number
REP=23.0.2 #CHANGE ME
sed -i.bak s/23\.0\.2/${REP}/g $OPENCV_SDK/sdk/java/build.gradle
sed -i.bak s/23\.0\.2/${REP}/g $OPENCV_SDK/samples/tutorial-1-camerapreview/build.gradle
Finally, set up the correct gradle wrapper. Gradle needs a clean directory to do this.
pushd $(mktemp -d)
gradle wrapper --gradle-version 2.5
mv -f gradle* $OPENCV_SDK/samples/tutorial-1-camerapreview
popd
You should now be all set. You can now browse to this directory with Android Studio and open up the project.
Build the tutoral on the command line with the following command:
./gradlew assembleDebug
It should build your apk, putting it in ./build/outputs/apk
This error message is always caused by the invalid XML content in the beginning element. For example, extra small dot “.” in the beginning of XML element.
Any characters before the “<?xml….
” will cause above “org.xml.sax.SAXParseException: Content is not allowed in prolog” error message.
A small dot “.” before the “<?xml….
To fix it, just delete all those weird characters before the “<?xml“

Bundler is launched from your app's root directory so it makes sure all needed gems are present to get your app working.If for some reason you no longer need a gem you'll have to run the
gem uninstall gem_name
as you stated above.So every time you run bundler it'll recheck dependencies
EDIT - 24.12.2014
I see that people keep coming to this question I decided to add a little something. The answer I gave was for the case when you maintain your gems global. Consider using a gem manager such as rbenv or rvm to keep sets of gems scoped to specific projects.
This means that no gems will be installed at a global level and therefore when you remove one from your project's Gemfile and rerun bundle then it, obviously, won't be loaded in your project. Then, you can run bundle clean (with the project dir) and it will remove from the system all those gems that were once installed from your Gemfile (in the same dir) but at this given time are no longer listed there.... long story short - it removes unused gems.
Confirmed!! make the user submit a post request to the affected url and the cached redirect is forgotten.
A quick win would be to enter this in the browser console if you can:
fetch('example.com/affected/link', {method: 'post'}).then(() => {})
Useful if you know the affected browser (especially during development).
Alternatively, if you have access to the previous 301 redirect page, then you can add this script to the page and anytime it is visited, the cached 301 will be forgotten.
Simply type in command prompt :
set path=%PATH%;D:\xampp\mysql\bin;
Here my path started from D so I used D: , you can use C: or E:
As you have mentioned it doesn't change anything.
First, you should redirect both standard input and standard error from the crontab execution like below:
*/2 * * * * /usr/bin/python /home/souza/Documets/Listener/listener.py > /tmp/listener.log 2>&1
Then you can view the file /tmp/listener.log
to see if the script executed as you expected.
Second, I guess what you mean by change anything is by watching the files created by your program:
f = file('counter', 'r+w')
json_file = file('json_file_create_server.json', 'r+w')
The crontab job above won't create these file in directory /home/souza/Documets/Listener
, as the cron job is not executed in this directory, and you use relative path in the program. So to create this file in directory /home/souza/Documets/Listener
, the following cron job will do the trick:
*/2 * * * * cd /home/souza/Documets/Listener && /usr/bin/python listener.py > /tmp/listener.log 2>&1
Change to the working directory and execute the script from there, and then you can view the files created in place.
I had a similar issue with an Angular project. In my polyfills.ts I had to add both:
import "core-js/es7/array";
import "core-js/es7/object";
In addition to enabling all the other IE 11 defaults. (See comments in polyfills.ts if using angular)
After adding these imports the error went away and my Object data populated as intended.

There are multiple settings for adjusting the legend size. The two I find most useful are:
legend(..., labelspacing=0.2)
will reduce the spacing between entries to 2 points. The default on my install is about 0.5.legend(..., prop={'size':8})
. The default on my install is about 14 points.In addition, the legend documentation lists a number of other padding and spacing parameters including: borderpad
, handlelength
, handletextpad
, borderaxespad
, and columnspacing
. These all follow the same form as labelspacing and area also in multiples of fontsize.
These values can also be set as the defaults for all figures using the matplotlibrc file.
About the server can deliver to the clients the root cert or not, extracted from the RFC-5246 'The Transport Layer Security (TLS) Protocol Version 1.2' doc it says:
certificate_list
This is a sequence (chain) of certificates. The sender's certificate MUST come first in the list. Each following certificate MUST directly certify the one preceding it. Because certificate validation requires that root keys be distributed independently, the self-signed certificate that specifies the root certificate authority MAY be omitted from the chain, under the
assumption that the remote end must already possess it in order to validate it in any case.
About the term 'MAY', extracted from the RFC-2119 "Best Current Practice" says:
5.MAY
This word, or the adjective "OPTIONAL", mean that an item is truly optional. One vendor may choose to include the item because a
particular marketplace requires it or because the vendor feels that
it enhances the product while another vendor may omit the same item.
An implementation which does not include a particular option MUST be
prepared to interoperate with another implementation which does
include the option, though perhaps with reduced functionality. In the same vein an implementation which does include a particular option
MUST be prepared to interoperate with another implementation which
does not include the option (except, of course, for the feature the
option provides.)
In conclusion, the root may be at the certification path delivered by the server in the handshake.
A practical use.
Think about, not in navigator user terms, but on a transfer tool at a server in a militarized zone with limited internet access.
The server, playing the client role at the transfer, receives all the certs path from the server.
All the certs in the chain should be checked to be trusted, root included.
The only way to check this is the root be included at the certs path in transfer time, being matched against a previously declared as 'trusted' local copy of them.

Please see this for more reference of type comparisons in PHP. It should give you a clear understanding.
As an adaption of @Mike Fuchs answer, here's an even smaller solution. I'm using the Fody.AutoDependencyPropertyMarker
to reduce some of the boiler plate.
The Class
public class EventCommand : TriggerAction<DependencyObject>
{
[AutoDependencyProperty]
public ICommand Command { get; set; }
protected override void Invoke(object parameter)
{
if (Command != null)
{
if (Command.CanExecute(parameter))
{
Command.Execute(parameter);
}
}
}
}
The EventArgs
public class VisibleBoundsArgs : EventArgs
{
public Rect VisibleVounds { get; }
public VisibleBoundsArgs(Rect visibleBounds)
{
VisibleVounds = visibleBounds;
}
}
The XAML
<local:ZoomableImage>
<i:Interaction.Triggers>
<i:EventTrigger EventName="VisibleBoundsChanged" >
<local:EventCommand Command="{Binding VisibleBoundsChanged}" />
</i:EventTrigger>
</i:Interaction.Triggers>
</local:ZoomableImage>
The ViewModel
public ICommand VisibleBoundsChanged => _visibleBoundsChanged ??
(_visibleBoundsChanged = new RelayCommand(obj => SetVisibleBounds(((VisibleBoundsArgs)obj).VisibleVounds)));
When magento mode is default it showws such error Change magento mode to developer with
php bin/magento deploy:mode:set developer
then check your error on your browser and resolve that
How about something like this:
public static Object GetPropValue(this Object obj, String name) {
foreach (String part in name.Split('.')) {
if (obj == null) { return null; }
Type type = obj.GetType();
PropertyInfo info = type.GetProperty(part);
if (info == null) { return null; }
obj = info.GetValue(obj, null);
}
return obj;
}
public static T GetPropValue<T>(this Object obj, String name) {
Object retval = GetPropValue(obj, name);
if (retval == null) { return default(T); }
// throws InvalidCastException if types are incompatible
return (T) retval;
}
This will allow you to descend into properties using a single string, like this:
DateTime now = DateTime.Now;
int min = GetPropValue<int>(now, "TimeOfDay.Minutes");
int hrs = now.GetPropValue<int>("TimeOfDay.Hours");
You can either use these methods as static methods or extensions.
Generally when I want to create a JSON or YAML string, I start out by building the Perl data structure, and then running a simple conversion on it. You could put a UI in front of the Perl data structure generation, e.g. a web form.
Converting a structure to JSON is very straightforward:
use strict;
use warnings;
use JSON::Any;
my $data = { arbitrary structure in here };
my $json_handler = JSON::Any->new(utf8=>1);
my $json_string = $json_handler->objToJson($data);
You can also use split
and join
:
"Sonic Free Games".split(" ").join("-").toLowerCase(); //sonic-free-games
I'm going to provide a functional (immutable) way of doing it.
The standard and easy way of doing it is to use slicing:
index_to_remove = 3
data = [*range(5)]
new_data = data[:index_to_remove] + data[index_to_remove + 1:]
print(f"data: {data}, new_data: {new_data}")
Output:
data: [0, 1, 2, 3, 4], new_data: [0, 1, 2, 4]
Use list comprehension:
data = [*range(5)]
new_data = [v for i, v in enumerate(data) if i != index_to_remove]
print(f"data: {data}, new_data: {new_data}")
Output:
data: [0, 1, 2, 3, 4], new_data: [0, 1, 2, 4]
Use filter function:
index_to_remove = 3
data = [*range(5)]
new_data = [*filter(lambda i: i != index_to_remove, data)]
Output:
data: [0, 1, 2, 3, 4], new_data: [0, 1, 2, 4]
Using masking. Masking is provided by itertools.compress function in the standard library:
from itertools import compress
index_to_remove = 3
data = [*range(5)]
mask = [1] * len(data)
mask[index_to_remove] = 0
new_data = [*compress(data, mask)]
print(f"data: {data}, mask: {mask}, new_data: {new_data}")
Output:
data: [0, 1, 2, 3, 4], mask: [1, 1, 1, 0, 1], new_data: [0, 1, 2, 4]
Use itertools.filterfalse function from Python standard library
from itertools import filterfalse
index_to_remove = 3
data = [*range(5)]
new_data = [*filterfalse(lambda i: i == index_to_remove, data)]
print(f"data: {data}, new_data: {new_data}")
Output:
data: [0, 1, 2, 3, 4], new_data: [0, 1, 2, 4]
I guess you want to decide which of 4:3 and 16:9 is the best fit.
function getAspectRatio(width, height) {
var ratio = width / height;
return ( Math.abs( ratio - 4 / 3 ) < Math.abs( ratio - 16 / 9 ) ) ? '4:3' : '16:9';
}
