In VBA, the !=
operator is the Not
operator, like this:
If Not strTest = "" Then ...
def _grateest_common_devisor_euclid(p, q):
if q==0 :
return p
else:
reminder = p%q
return _grateest_common_devisor_euclid(q, reminder)
print(_grateest_common_devisor_euclid(8,3))
One more way is to extend the application (as my application was to inherit and customize the parent). It invokes the parent and its commandlinerunner automatically.
@SpringBootApplication
public class ChildApplication extends ParentApplication{
public static void main(String[] args) {
SpringApplication.run(ChildApplication.class, args);
}
}
Not sure why it's doing that. Try -s
with the -o
option to set the output file instead of >
.
The trick is pretty simple... The request cycle is still pretty much alive. You can just add a new variable that will create a temporary, calling
app.get('some/url/endpoint', middleware1, middleware2);
Since you can handle your request in the first middleware
(req, res, next) => {
var yourvalue = anyvalue
}
In middleware 1 you handle your logic and store your value like below:
req.anyvariable = yourvalue
In middleware 2 you can catch this value from middleware 1 doing the following:
(req, res, next) => {
var storedvalue = req.yourvalue
}
Thats an if/else statement equilavent to
if(row % 2 == 1){
System.out.print("<");
}else{
System.out.print("\r>");
}
<style>
a {
color: ;
}
</style>
This code changes the color from the default to what is specified in the style. Using a:hover, you can change the color of the text from the default on hover.
You can use a time_t
struct and clock()
function from time.h.
Store the start time in a time_t
struct by using clock()
and check the elapsed time by comparing the difference between stored time and current time.
I solved mine by using an Import directive under my Page directive. You may also want to add the namespace to your Inherits attribute of your Page directive.
Since it appears that your default namespace is "stman.Members", try:
<%@ Page Title="" Language="C#" MasterPageFile="~/Members/Members.master" AutoEventWireup="true" CodeFile="Jobs.aspx.cs" Inherits="stman.Members.Members_Jobs" %>
<%@ Import Namespace="stman.Members"%>
Additionally, data that I wanted to pass between aspx.cs and aspx, I put inside a static class inside the namespace. That static class was available to move data around in the name space and no longer has a "not in context" error.
if you are interested in a ready solution then you may look at HumanizerCpp library (https://github.com/trodevel/HumanizerCpp) - it is a port of C# Humanizer library and it does exactly what you want.
It can even convert to ordinals and currently supports 3 languages: English, German and Russian.
Example:
const INumberToWordsConverter * e = Configurator::GetNumberToWordsConverter( "en" );
std::cout << e->Convert( 123 ) << std::endl;
std::cout << e->Convert( 1234 ) << std::endl;
std::cout << e->Convert( 12345 ) << std::endl;
std::cout << e->Convert( 123456 ) << std::endl;
std::cout << std::endl;
std::cout << e->ConvertToOrdinal( 1001 ) << std::endl;
std::cout << e->ConvertToOrdinal( 1021 ) << std::endl;
const INumberToWordsConverter * g = Configurator::GetNumberToWordsConverter( "de" );
std::cout << std::endl;
std::cout << g->Convert( 123456 ) << std::endl;
const INumberToWordsConverter * r = Configurator::GetNumberToWordsConverter( "ru" );
std::cout << r->ConvertToOrdinal( 1112 ) << std::endl;
Output:
one hundred and twenty-three
one thousand two hundred and thirty-four
twelve thousand three hundred and forty-five
one hundred and twenty-three thousand four hundred and fifty-six
thousand and first
thousand and twenty-first
einhundertdreiundzwanzigtausendvierhundertsechsundfünfzig

In any case you may take a look at the source code and reuse in your project or try to understand the logic. It is written in pure C++ without external libraries.

This is a simple solution with the function aggregate
:
aggregate(order_no ~ name, myvec, function(x) length(unique(x)))
I'd download PuTTY and run a telnet session on port 80 to the webserver you want
HEAD /resource HTTP/1.1
Host: www.example.com
You could alternatively download Perl and try LWP's HEAD command. Or write your own script.
When you do vagrant init , it replaces the vagrant file in your repo and can give you that error. So I would suggest you copy the original vagrant file from remote or a backup vagrant file and try vagrant up after that.
I came across same issue and I just copied the vagrant file from my remote repo and replaced the vagrant file I was trying to run. This synced the configurations in the vagrant file with the VM.
you may have some errors in your fields like
public class Search_costumer extends Activity {
// you may have some errors like this
int x =3/0;
// I have error in initializing this variable too
MySimpleOnGestureListener mySimpleOnGestureListener =new MySimpleOnGestureListener();
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
}
so my advice is to perform all initialization in onCreate method not directly in your fields
solve like that
public class Search_costumer extends Activity {
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// you may have some errors like this
int x =3/0;
// I have error in initializing this variable too
MySimpleOnGestureListener mySimpleOnGestureListener =new MySimpleOnGestureListener();
}
}
You have referenced the image as a path on your computer (C:\etc\etc)......is it located there? You didn't answer what others have asked. I have taken your code, placed it in dreamweaver and it works apart from the image as I don't have that stored.
Check the location and then let us know.
I'm not using JAX-RS, but I've got a similar scenario where I use:
response.setStatus(HttpStatus.INTERNAL_SERVER_ERROR.value());
After reading your comment on my previous answer I thought I might put this as a separate answer.
Although I appreciate your approach of trying to do it manually to get a better grasp on jQuery I do still emphasise the merit in using existing frameworks.
That said, here is a solution. I've modified some of your css and and HTML just to make it easier for me to work with
WORKING JS FIDDLE - http://jsfiddle.net/HsEne/15/
This is the jQuery
$(document).ready(function(){
$('.sp').first().addClass('active');
$('.sp').hide();
$('.active').show();
$('#button-next').click(function(){
$('.active').removeClass('active').addClass('oldActive');
if ( $('.oldActive').is(':last-child')) {
$('.sp').first().addClass('active');
}
else{
$('.oldActive').next().addClass('active');
}
$('.oldActive').removeClass('oldActive');
$('.sp').fadeOut();
$('.active').fadeIn();
});
$('#button-previous').click(function(){
$('.active').removeClass('active').addClass('oldActive');
if ( $('.oldActive').is(':first-child')) {
$('.sp').last().addClass('active');
}
else{
$('.oldActive').prev().addClass('active');
}
$('.oldActive').removeClass('oldActive');
$('.sp').fadeOut();
$('.active').fadeIn();
});
});
So now the explanation.
Stage 1
1) Load the script on document ready.
2) Grab the first slide and add a class 'active' to it so we know which slide we are dealing with.
3) Hide all slides and show active slide. So now slide #1 is display block and all the rest are display:none;
Stage 2
Working with the button-next click event.
1) Remove the current active class from the slide that will be disappearing and give it the class oldActive so we know that it is on it's way out.
2) Next is an if statement to check if we are at the end of the slideshow and need to return to the start again. It checks if oldActive (i.e. the outgoing slide) is the last child. If it is, then go back to the first child and make it 'active'. If it's not the last child, then just grab the next element (using .next() ) and give it class active.
3) We remove the class oldActive because it's no longer needed.
4) fadeOut all of the slides
5) fade In the active slides
Step 3
Same as in step two but using some reverse logic for traversing through the elements backwards.
It's important to note there are thousands of ways you can achieve this. This is merely my take on the situation.
The error message tells the exact reason: "abstract methods cannot have a body".
They can only be defined in abstract classes and interfaces (interface methods are implicitly abstract!) and the idea is, that the subclass implements the method.
Example:
public abstract class AbstractGreeter {
public abstract String getHelloMessage();
public void sayHello() {
System.out.println(getHelloMessage());
}
}
public class FrenchGreeter extends AbstractGreeter{
// we must implement the abstract method
@Override
public String getHelloMessage() {
return "bonjour";
}
}
nflog is better
sudo apt-get -y install ulogd2
ICMP Block rule example:
iptables=/sbin/iptables
# Drop ICMP (PING)
$iptables -t mangle -A PREROUTING -p icmp -j NFLOG --nflog-prefix 'ICMP Block'
$iptables -t mangle -A PREROUTING -p icmp -j DROP
And you can search prefix "ICMP Block" in log:
/var/log/ulog/syslogemu.log
It's an option that you pass to the read()
command:
context = new org.apache.spark.sql.SQLContext(sc)
var data = context.read.option("header","true").csv("<path>")
SELECT CONVERT(char(10), GetDate(),126)
Limiting the size of the varchar chops of the hour portion that you don't want.
Two ways. Symbols (:foo
notation) or constants (FOO
notation).
Symbols are appropriate when you want to enhance readability without littering code with literal strings.
postal_code[:minnesota] = "MN"
postal_code[:new_york] = "NY"
Constants are appropriate when you have an underlying value that is important. Just declare a module to hold your constants and then declare the constants within that.
module Foo
BAR = 1
BAZ = 2
BIZ = 4
end
flags = Foo::BAR | Foo::BAZ # flags = 3

If you are passing the enum value around (for example, storing it in a database) and you need to be able to translate the value back into the symbol, there's a mashup of both approaches
COMMODITY_TYPE = {
currency: 1,
investment: 2,
}
def commodity_type_string(value)
COMMODITY_TYPE.key(value)
end
COMMODITY_TYPE[:currency]
This approach inspired by andrew-grimm's answer https://stackoverflow.com/a/5332950/13468
I'd also recommend reading through the rest of the answers here since there are a lot of ways to solve this and it really boils down to what it is about the other language's enum that you care about
Just use a while loop:
var (i, sum) = (0, 0)
while (sum < 1000) {
sum += i
i += 1
}
The memset function is designed to be flexible and simple, even at the expense of speed. In many implementations, it is a simple while loop that copies the specified value one byte at a time over the given number of bytes. If you are wanting a faster memset (or memcpy, memmove, etc), it is almost always possible to code one up yourself.
The simplest customization would be to do single-byte "set" operations until the destination address is 32- or 64-bit aligned (whatever matches your chip's architecture) and then start copying a full CPU register at a time. You may have to do a couple of single-byte "set" operations at the end if your range doesn't end on an aligned address.
Depending on your particular CPU, you might also have some streaming SIMD instructions that can help you out. These will typically work better on aligned addresses, so the above technique for using aligned addresses can be useful here as well.
For zeroing out large sections of memory, you may also see a speed boost by splitting the range into sections and processing each section in parallel (where number of sections is the same as your number or cores/hardware threads).
Most importantly, there's no way to tell if any of this will help unless you try it. At a minimum, take a look at what your compiler emits for each case. See what other compilers emit for their standard 'memset' as well (their implementation might be more efficient than your compiler's).
I use one Factory
module that contains one (or more) constructor per class which calls the Init
member of each class.
For example a Point
class:
Class Point
Private X, Y
Sub Init(X, Y)
Me.X = X
Me.Y = Y
End Sub
A Line
class
Class Line
Private P1, P2
Sub Init(Optional P1, Optional P2, Optional X1, Optional X2, Optional Y1, Optional Y2)
If P1 Is Nothing Then
Set Me.P1 = NewPoint(X1, Y1)
Set Me.P2 = NewPoint(X2, Y2)
Else
Set Me.P1 = P1
Set Me.P2 = P2
End If
End Sub
And a Factory
module:
Module Factory
Function NewPoint(X, Y)
Set NewPoint = New Point
NewPoint.Init X, Y
End Function
Function NewLine(Optional P1, Optional P2, Optional X1, Optional X2, Optional Y1, Optional Y2)
Set NewLine = New Line
NewLine.Init P1, P2, X1, Y1, X2, Y2
End Function
Function NewLinePt(P1, P2)
Set NewLinePt = New Line
NewLinePt.Init P1:=P1, P2:=P2
End Function
Function NewLineXY(X1, Y1, X2, Y2)
Set NewLineXY = New Line
NewLineXY.Init X1:=X1, Y1:=Y1, X2:=X2, Y2:=Y2
End Function
One nice aspect of this approach is that makes it easy to use the factory functions inside expressions. For example it is possible to do something like:
D = Distance(NewPoint(10, 10), NewPoint(20, 20)
or:
D = NewPoint(10, 10).Distance(NewPoint(20, 20))
It's clean: the factory does very little and it does it consistently across all objects, just the creation and one Init
call on each creator.
And it's fairly object oriented: the Init
functions are defined inside the objects.
EDIT
I forgot to add that this allows me to create static methods. For example I can do something like (after making the parameters optional):
NewLine.DeleteAllLinesShorterThan 10
Unfortunately a new instance of the object is created every time, so any static variable will be lost after the execution. The collection of lines and any other static variable used in this pseudo-static method must be defined in a module.
A HashSet does not guarantee any order of its elements. If you need this guarantee, consider using a TreeSet to hold your elements.
However if you just need your elements sorted for this one occurrence, then just temporarily create a List and sort that:
Set<?> yourHashSet = new HashSet<>();
...
List<?> sortedList = new ArrayList<>(yourHashSet);
Collections.sort(sortedList);
Try this:
$('input[name=Comanda]')
.click(
function ()
{
$(this).hide();
}
);
For doing everything else you can use something like this one:
$('input[name=Comanda]')
.click(
function ()
{
$(this).hide();
$(".ClassNameOfShouldBeHiddenElements").hide();
}
);
For hidding any other elements based on their IDs, use this one:
$('input[name=Comanda]')
.click(
function ()
{
$(this).hide();
$("#FirstElement").hide();
$("#SecondElement").hide();
$("#ThirdElement").hide();
}
);
I implemented this in java and ran a unit test (source below). None of the above solutions work. This code passes the unit test. If anyone finds a unit test that does not pass, please let me know.
Code: NOTE: nearlyEqual(double,double)
returns true if the two numbers are very close.
/*
* @return integer code for which side of the line ab c is on. 1 means
* left turn, -1 means right turn. Returns
* 0 if all three are on a line
*/
public static int findSide(
double ax, double ay,
double bx, double by,
double cx, double cy) {
if (nearlyEqual(bx-ax,0)) { // vertical line
if (cx < bx) {
return by > ay ? 1 : -1;
}
if (cx > bx) {
return by > ay ? -1 : 1;
}
return 0;
}
if (nearlyEqual(by-ay,0)) { // horizontal line
if (cy < by) {
return bx > ax ? -1 : 1;
}
if (cy > by) {
return bx > ax ? 1 : -1;
}
return 0;
}
double slope = (by - ay) / (bx - ax);
double yIntercept = ay - ax * slope;
double cSolution = (slope*cx) + yIntercept;
if (slope != 0) {
if (cy > cSolution) {
return bx > ax ? 1 : -1;
}
if (cy < cSolution) {
return bx > ax ? -1 : 1;
}
return 0;
}
return 0;
}
Here's the unit test:

I had a similar problem when developing a Django project. I couldn't use OrderedDict, because I was running an old version of python, so the solution was to use Django's SortedDict class:
https://code.djangoproject.com/wiki/SortedDict
e.g.,
from django.utils.datastructures import SortedDict
d2 = SortedDict()
d2['b'] = 1
d2['a'] = 2
d2['c'] = 3
Note: This answer is originally from 2011. If you have access to Python version 2.7 or higher, then you should have access to the now standard collections.OrderedDict
, of which many examples have been provided by others in this thread.
First of all, link_to is a html tag helper, its second argument is the url, followed by html_options. What you would like is to pass account_id as a url parameter to the path. If you have set up named routes correctly in routes.rb, you can use path helpers.
link_to "+ Service", new_my_service_path(:account_id => acct.id)
I think the best practice is to pass model values as a param nested within :
link_to "+ Service", new_my_service_path(:my_service => { :account_id => acct.id })
# my_services_controller.rb
def new
@my_service = MyService.new(params[:my_service])
end
And you need to control that account_id is allowed for 'mass assignment'. In rails 3 you can use powerful controls to filter valid params within the controller where it belongs. I highly recommend.
http://apidock.com/rails/ActiveModel/MassAssignmentSecurity/ClassMethods
Also note that if account_id is not freely set by the user (e.g., a user can only submit a service for the own single account_id, then it is better practice not to send it via the request, but set it within the controller by adding something like:
@my_service.account_id = current_user.account_id
You can surely combine the two if you only allow users to create service on their own account, but allow admin to create anyone's by using roles in attr_accessible.
hope this helps

Request timed out means that the local host did not receive a response from the destination host, but it was able to reach it. Destination host unreachable means that there was no valid route to the requested host.
From HTML 4 spec, which should be consistent across almost all browsers:
http://www.w3.org/TR/html401/interact/forms.html#checkbox
Checkboxes (and radio buttons) are on/off switches that may be toggled by the user. A switch is "on" when the control element's checked attribute is set. When a form is submitted, only "on" checkbox controls can become successful.
Successful is defined as follows:
A successful control is "valid" for submission. Every successful control has its control name paired with its current value as part of the submitted form data set. A successful control must be defined within a FORM element and must have a control name.
The shortest and best way is already answered, but the first thing I thought of was the mathematical way, so here it is:
def intlist(n):
q = n
ret = []
while q != 0:
q, r = divmod(q, 10) # Divide by 10, see the remainder
ret.insert(0, r) # The remainder is the first to the right digit
return ret
print intlist(3)
print '-'
print intlist(10)
print '--'
print intlist(137)
It's just another interesting approach, you definitely don't have to use such a thing in practical use cases.

I know this is an old thread, but I just spent 3 hours trying to figure out what my issue was. I ordinarily know what this error means, but you can run into this in a more subtle way as well. My issue was my client class (the one calling a static method from an instance class) had a property of a different type but named the same as the static method. The error reported by the compiler was the same as reported here, but the issue was basically name collision.
For anyone else getting this error and none of the above helps, try fully qualifying your instance class with the namespace name. ..() so the compiler can see the exact name you mean.
Well, I think it would be a bad idea to replicate the code which is already present in classes like SimpleDateFormat
.
On the other hand, personally I'd suggest avoiding Calendar
and Date
entirely if you can, and using Joda Time instead, as a far better designed date and time API. For example, you need to be aware that SimpleDateFormat
is not thread-safe, so you either need thread-locals, synchronization, or a new instance each time you use it. Joda parsers and formatters are thread-safe.
A fix for this problem is to add swap

) space to the instance.
Paging works by creating an area on your hard drive and using it for extra memory, this memory is much slower than normal memory however much more of it is available.
To add this extra space to your instance you type:
sudo /bin/dd if=/dev/zero of=/var/swap.1 bs=1M count=1024
sudo /sbin/mkswap /var/swap.1
sudo chmod 600 /var/swap.1
sudo /sbin/swapon /var/swap.1
If you need more than 1024 then change that to something higher.
To enable it by default after reboot, add this line to /etc/fstab:
/var/swap.1 swap swap defaults 0 0
When you use trusted connections, username and password are IGNORED, because SQL Server using windows authentication.
Methods that read data into byte slices return the number of bytes read. You should save that number and then use it to create your string. If n
is the number of bytes read, your code would look like this:
s := string(byteArray[:n])
To convert the full string, this can be used:
s := string(byteArray[:len(byteArray)])
This is equivalent to:
s := string(byteArray)
If for some reason you don't know n
, you could use the bytes
package to find it, assuming your input doesn't have a null character embedded in it.
n := bytes.Index(byteArray, []byte{0})
Or as icza pointed out, you can use the code below:
n := bytes.IndexByte(byteArray, 0)
SQL doesn't typically allow you to reference column aliases in WHERE, GROUP BY or HAVING clauses. MySQL does support referencing column aliases in the GROUP BY and HAVING, but I stress that it will cause problems when porting such queries to other databases.
When in doubt, use the actual column name:
SELECT t.lat AS latitude
FROM poi_table t
WHERE t.lat < 500
I added a table alias to make it easier to see what is an actual column vs alias.
A computed column, like the one you see here:
SELECT *,
( 6371*1000 * acos( cos( radians(42.3936868308) ) * cos( radians( lat ) ) * cos( radians( lon ) - radians(-72.5277256966) ) + sin( radians(42.3936868308) ) * sin( radians( lat ) ) ) ) AS distance
FROM poi_table
WHERE distance < 500;
...doesn't change that you can not reference a column alias in the WHERE clause. For that query to work, you'd have to use:
SELECT *,
( 6371*1000 * acos( cos( radians(42.3936868308) ) * cos( radians( lat ) ) * cos( radians( lon ) - radians(-72.5277256966) ) + sin( radians(42.3936868308) ) * sin( radians( lat ) ) ) ) AS distance
FROM poi_table
WHERE ( 6371*1000 * acos( cos( radians(42.3936868308) ) * cos( radians( lat ) ) * cos( radians( lon ) - radians(-72.5277256966) ) + sin( radians(42.3936868308) ) * sin( radians( lat ) ) ) ) < 500;
Be aware that using a function on a column (IE: RADIANS(lat)
) will render an index useless, if one exists on the column.
Assuming I am understanding your question and setup correctly,
If you're trying to use the build number in your script, you have two options:
1) When calling ant, use: ant -Dbuild_parameter=${BUILD_NUMBER}
2) Change your script so that:
<property environment="env" />
<property name="build_parameter" value="${env.BUILD_NUMBER}"/>
It got simplified with newer version of rxjs .
import {map} from 'rxjs/operators';
import {Observable,of, from } from 'rxjs';
Instead of chaining we need to pipe . For example
Old syntax :
source.map().switchMap().subscribe()
New Syntax:
source.pipe(map(), switchMap()).subscribe()
Note: Some operators have a name change due to name collisions with JavaScript reserved words! These include:
do
-> tap
,
catch
-> catchError
switch
-> switchAll
finally
-> finalize
I am writing this answer partly to help myself as I keep checking docs everytime I need to import an operator . Let me know if something can be done better way.
import { Rx } from 'rxjs/Rx'
;This imports the entire library. Then you don't need to worry about loading each operator . But you need to append Rx. I hope tree-shaking will optimize and pick only needed funcionts( need to verify ) As mentioned in comments , tree-shaking can not help. So this is not optimized way.
public cache = new Rx.BehaviorSubject('');
Or you can import individual operators .
This will Optimize your app to use only those files :
import { _______ } from 'rxjs/_________';
This syntax usually used for main Object like Rx
itself or Observable
etc.,
Keywords which can be imported with this syntax
Observable, Observer, BehaviorSubject, Subject, ReplaySubject
import 'rxjs/add/observable/__________';
Update for Angular 5
With Angular 5, which uses rxjs 5.5.2+
import { empty } from 'rxjs/observable/empty';
import { concat} from 'rxjs/observable/concat';
These are usually accompanied with Observable directly. For example
Observable.from()
Observable.of()
Other such keywords which can be imported using this syntax:
concat, defer, empty, forkJoin, from, fromPromise, if, interval, merge, of,
range, throw, timer, using, zip
import 'rxjs/add/operator/_________';
Update for Angular 5
With Angular 5, which uses rxjs 5.5.2+
import { filter } from 'rxjs/operators/filter';
import { map } from 'rxjs/operators/map';
These usually come in the stream after the Observable is created. Like flatMap
in this code snippet:
Observable.of([1,2,3,4])
.flatMap(arr => Observable.from(arr));
Other such keywords using this syntax:
audit, buffer, catch, combineAll, combineLatest, concat, count, debounce, delay,
distinct, do, every, expand, filter, finally, find , first, groupBy,
ignoreElements, isEmpty, last, let, map, max, merge, mergeMap, min, pluck,
publish, race, reduce, repeat, scan, skip, startWith, switch, switchMap, take,
takeUntil, throttle, timeout, toArray, toPromise, withLatestFrom, zip
FlatMap:
flatMap
is alias to mergeMap
so we need to import mergeMap
to use flatMap
.
Note for /add
imports :
We only need to import once in whole project. So its advised to do it at a single place. If they are included in multiple files, and one of them is deleted, the build will fail for wrong reasons.
First treat the number like a string
number = 9876543210
number = str(number)
Then to get the first digit:
number[0]
The fourth digit:
number[3]
EDIT:
This will return the digit as a character, not as a number. To convert it back use:
int(number[0])
Easy.. Try this
$("table td img.delete").click(function () {
$(this).parent().parent().parent().fadeTo(400, 0, function () {
$(this).remove();
});
return false;
});
!=
For example,
if ("apple" != "orange")
// true, the string "apple" is not equal to the string "orange"
Means not. See also the logical operators list. Also, when you see triple characters, it's a type sensitive comparison. (e.g. if (1 === '1')
[not equal])
You are simply looking for common patterns in strings. I would have thought a regular expression would be a more efficient way of doing this as PHP implements this with preg_match so little code to write and probably massively quicker. For example:
case preg_match('/^users./'):
// do something here
break;
You can also use the RestSharp library for example
var userName = "myuser";
var password = "mypassword";
var host = "170.170.170.170:333";
var client = new RestClient("https://" + host + "/method1");
client.Authenticator = new HttpBasicAuthenticator(userName, password);
var request = new RestRequest(Method.POST);
request.AddHeader("Accept", "application/json");
request.AddHeader("Cache-Control", "no-cache");
request.AddHeader("Content-Type", "application/json");
request.AddParameter("application/json","{}",ParameterType.RequestBody);
IRestResponse response = client.Execute(request);

When adding new element with jquery plugin calls, you can do like the following:
$('<div>...</div>').hoverCard(function(){...}).appendTo(...)
response.writeHead(301,
{Location: 'http://whateverhostthiswillbe:8675/'+newRoom}
);
response.end();
I faced a similar kind of issue while passing a string to Database table using SQL BulkCopy option. The string i was passing was of 3 characters whereas the destination column length was varchar(20)
. I tried trimming the string before inserting into DB using Trim()
function to check if the issue was due to any space (leading and trailing) in the string. After trimming the string, it worked fine.
You can try text.Trim()
My special case is:

hope above solution is useful for your.
Using jQuery, I would suggest a shorter solution.
var elementClicked;
$("element").click(function(){
elementClicked = true;
});
if( elementClicked != true ) {
alert("element not clicked");
}else{
alert("element clicked");
}
("element" here is to be replaced with the actual name tag)
I understand that the Q does not want to use a library, but I will offer this for others coming from Google searches. @EricRowell mentioned a good plugin, but, there is also another plugin you can try, html2canvas.
In our case we are using layered transparent PNG's with z-index
as a "product builder" widget. Html2canvas worked brilliantly to boil the stack down without pushing images, nor using complexities, workarounds, and the "non-responsive" canvas itself. We were not able to do this smoothly/sane with the vanilla canvas+JS.
First use z-index
on absolute divs to generate layered content within a relative positioned wrapper. Then pipe the wrapper through html2canvas to get a rendered canvas, which you may leave as-is, or output as an image so that a client may save it.
In addition to the accepted answer I would like to give an answer that shows how to iterate directly over the Newtonsoft collections. It uses less code and I'm guessing its more efficient as it doesn't involve converting the collections.
using Newtonsoft.Json;
using Newtonsoft.Json.Linq;
//Parse the data
JObject my_obj = JsonConvert.DeserializeObject<JObject>(your_json);
foreach (KeyValuePair<string, JToken> sub_obj in (JObject)my_obj["ADDRESS_MAP"])
{
Console.WriteLine(sub_obj.Key);
}
I started doing this myself because JsonConvert automatically deserializes nested objects as JToken (which are JObject, JValue, or JArray underneath I think).
I think the parsing works according to the following principles:
Every object is abstracted as a JToken
Cast to JObject where you expect a Dictionary
Cast to JValue if the JToken represents a terminal node and is a value
Cast to JArray if its an array
JValue.Value gives you the .NET type you need
The problem is, you are creating a transport
object and using it's connect method to authenticate yourself.
But then you use a static
method to send the message which ignores authentication done by the object.
So, you should either use the sendMessage(message, message.getAllRecipients())
method on the object or use an authenticator as suggested by others to get authorize
through the session.
Here's the Java Mail FAQ, you need to read.
I encountered the same problem today.
I followed the official instructions, but I didn't noticed that I SHOULD
run command
"chmod a+r /etc/udev/rules.d/51-android.rules"
After I set this file to world readable and re-plug my usb cable,the status became unauthorized. Then just grant the permission and everything goes fine.
If you’re not opposed to jquery, this can be done in one line:
jQuery 1.7+
$("#myEl").off()
jQuery < 1.7
$('#myEl').replaceWith($('#myEl').clone());
Here’s an example:
>>> import arrow
>>> now = arrow.utcnow().format('YYYY-MM-DDTHH:mm:ss.SSS')
>>> now
'2018-11-28T21:34:59.235'
>>> zulu = "{}Z".format(now)
>>> zulu
'2018-11-28T21:34:59.235Z'
Or, to get it in one fell swoop:
>>> zulu = "{}Z".format(arrow.utcnow().format('YYYY-MM-DDTHH:mm:ss.SSS'))
>>> zulu
'2018-11-28T21:54:49.639Z'
I have also experienced the same problem when uploading the magento project to my webserver, In my case the zip file is corrupted during the upload process and many of my php files are also damaged. I have uploaded via ftp. I have found the solution for this. If you are making the zip file from linux machine, try to use command line tool (For example: ie;
zip -r my_archive.zip /path/of/files/to/compress/
)
and do upload to your web server from windows filezilla client.

package main
import "fmt"
import "strconv"
func FloatToString(input_num float64) string {
// to convert a float number to a string
return strconv.FormatFloat(input_num, 'f', 6, 64)
}
func main() {
fmt.Println(FloatToString(21312421.213123))
}
If you just want as many digits precision as possible, then the special precision -1 uses the smallest number of digits necessary such that ParseFloat will return f exactly. Eg
strconv.FormatFloat(input_num, 'f', -1, 64)
Personally I find fmt
easier to use. (Playground link)
fmt.Printf("x = %.6f\n", 21312421.213123)
Or if you just want to convert the string
fmt.Sprintf("%.6f", 21312421.213123)

The problem is your query returned false
meaning there was an error in your query. After your query you could do the following:
if (!$result) {
die(mysqli_error($link));
}
Or you could combine it with your query:
$results = mysqli_query($link, $query) or die(mysqli_error($link));
That will print out your error.
Also... you need to sanitize your input. You can't just take user input and put that into a query. Try this:
$query = "SELECT * FROM shopsy_db WHERE name LIKE '%" . mysqli_real_escape_string($link, $searchTerm) . "%'";
In reply to: Table 'sookehhh_shopsy_db.sookehhh_shopsy_db' doesn't exist
Are you sure the table name is sookehhh_shopsy_db? maybe it's really like users or something.
This can happens when:
e.g. something like this happened:
$ cd submodule
$ emacs my_source_file # edit some file(s)
$ git commit -am "Making some changes but will forget to push!"
Should have submodule pushed at this point.
$ cd .. # back to parent repository
$ git commit -am "updates to parent repository"
$ git push origin master
As a result, the missing commits could not possibly be found by the remote user because they are still on the local disk.
Informa the person who modified the submodule to push, i.e.
$ cd submodule
$ git push
It has already been answered, the best way work-around is to convert the Stored Procedure into an SQL Function or a View.
The short answer, just as mentioned above, is that you cannot directly JOIN a Stored Procedure in SQL, not unless you create another stored procedure or function using the stored procedure's output into a temporary table and JOINing the temporary table, as explained above.
I will answer this by converting your Stored Procedure into an SQL function and show you how to use it inside a query of your choice.
CREATE FUNCTION fnMyFunc()
RETURNS TABLE AS
RETURN
(
SELECT tenant.ID AS TenantID,
SUM(ISNULL(trans.Amount,0)) AS TenantBalance
FROM tblTenant tenant
LEFT JOIN tblTransaction trans ON tenant.ID = trans.TenantID
GROUP BY tenant.ID
)
Now to use that function, in your SQL...
SELECT t.TenantName,
t.CarPlateNumber,
t.CarColor,
t.Sex,
t.SSNO,
t.Phone,
t.Memo,
u.UnitNumber,
p.PropertyName
FROM tblTenant t
LEFT JOIN tblRentalUnit u ON t.UnitID = u.ID
LEFT JOIN tblProperty p ON u.PropertyID = p.ID
LEFT JOIN dbo.fnMyFunc() AS a
ON a.TenantID = t.TenantID
ORDER BY p.PropertyName, t.CarPlateNumber
If you wish to pass parameters into your function from within the above SQL, then I recommend you use CROSS APPLY
or CROSS OUTER APPLY
.
Read up on that here.
Cheers
My issue is that I accidentally installed another site as the default site instead of the IIS default (by opening another project.) I had to remove the default site and repoint it to the default location C:\inetpub\wwwroot
using my domain login as the user to bypass with then just reopened my project that I was trying to run (the one showing this error) and it was all honky dorry
First you to add a class then remove id
<script type="text/javascript">
$(document).ready(function(){
$("#page_navigation1").addClass("page_navigation");
$("#add").click(function(){
$(".page_navigation").attr("id","page_navigation1");
});
$("#remove").click(function(){
$(".page_navigation").removeAttr("id");
});
});
</script>
Update: To create a popup menu in android with Kotlin refer my answer here.
To create a popup menu in android with Java:
Create a layout file activity_main.xml
under res/layout
directory which contains only one button.
Filename: activity_main.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".MainActivity" >
<Button
android:id="@+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:layout_marginLeft="62dp"
android:layout_marginTop="50dp"
android:text="Show Popup" />
</RelativeLayout>
Create a file popup_menu.xml
under res/menu
directory
It contains three items as shown below.
Filename: poupup_menu.xml
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:id="@+id/one"
android:title="One"/>
<item
android:id="@+id/two"
android:title="Two"/>
<item
android:id="@+id/three"
android:title="Three"/>
</menu>
MainActivity class which displays the popup menu on button click.
Filename: MainActivity.java
public class MainActivity extends Activity {
private Button button1;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
button1 = (Button) findViewById(R.id.button1);
button1.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
//Creating the instance of PopupMenu
PopupMenu popup = new PopupMenu(MainActivity.this, button1);
//Inflating the Popup using xml file
popup.getMenuInflater()
.inflate(R.menu.popup_menu, popup.getMenu());
//registering popup with OnMenuItemClickListener
popup.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
public boolean onMenuItemClick(MenuItem item) {
Toast.makeText(
MainActivity.this,
"You Clicked : " + item.getTitle(),
Toast.LENGTH_SHORT
).show();
return true;
}
});
popup.show(); //showing popup menu
}
}); //closing the setOnClickListener method
}
}
To add programmatically:
PopupMenu menu = new PopupMenu(this, view);
menu.getMenu().add("One");
menu.getMenu().add("Two");
menu.getMenu().add("Three");
menu.show();
Follow this link for creating menu programmatically.
You need to handle an event on Form1 that is raised as a result of user interaction. For example, if you have a "Settings" button that the user clicks in order to show the settings form (Form2), you should handle the Click
event for that button:
private void settingsButton_Click(Object sender, EventArgs e)
{
// Create a new instance of the Form2 class
Form2 settingsForm = new Form2();
// Show the settings form
settingsForm.Show();
}
In addition to the Show
method, you could also choose to use the ShowDialog
method. The difference is that the latter shows the form as a modal dialog, meaning that the user cannot interact with the other forms in your application until they close the modal form. This is the same way that a message box works. The ShowDialog
method also returns a value indicating how the form was closed.
When the user closes the settings form (by clicking the "X" in the title bar, for example), Windows will automatically take care of closing it.
If you want to close it yourself before the user asks to close it, you can call the form's Close
method:
this.Close();
Deleting the folders haven't worked for me i have go control panel and repaired
Visual Studio Installer Projects extensions for VS 2013.
And it worked for me
Try:
Install all the required tools and configurations using Microsoft's windows-build-tools by running npm install -g windows-build-tools
from an elevated PowerShell (run as Administrator).
Handle the Worksheet_Change
event or the Workbook_SheetChange
event.
The event handlers take an argument "Target As Range", so you can check if the range that's changing includes the cell you're interested in.
Can directly used as
android:value="6587000"
in place of
android:value="@integer/google_play_services_version"

Set below code in RouteConfig.cs in App_Start folder
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Account", action = "Login", id = UrlParameter.Optional });
}
IF still not working then do below steps
Second Way : You simple follow below steps,
1) Right click on your Project
2) Select Properties
3) Select Web option and then Select Specific Page (Controller/View) and then set your login page
Here, Account is my controller and Login is my action method (saved in Account Controller)
Please take a look attached screenshot.

android:listSelector="#666666"
(or you may specify a resource link instead of color value)
Programmatical:
listView.setSelector(Drawable selector);
listView.setSelector(int resourceId);
listView.setChoiceMode(int mode);
mode can be one of these: AbsListView.CHOICE_MODE_SINGLE, AbsListView.CHOICE_MODE_MULTIPLE, AbsListView.CHOICE_MODE_NONE (default)
(AbsListView is the abstract ancestor for the ListView class)
P.S. manipulations with onItemClick and changing view background are bankrupt, because a view itself is a temporary object. Hence you must not to track a view.
If our list is long enough, the views associated with scrolled out items will be removed from hierarchy, and will be recreated when those items will shown again (with cached display options, such as background). So, the view we have tracked is now not an actual view of the item, and changing its background does nothing to the actual item view. As a result we have multiple items selected.
You need to specifically enable the pdo_mysql plugin. Assuming you're using a standard PHP installation, then generally you would simply need to add this to your PHP.ini file:
extension=pdo_mysql.so
You need to ensure that this file exists in the extension directory though.
Adding pdo_pgsql.so
doesn't help because that is for PostgreSQL.
Additionally, you should ensure that you restart the web-server after you make the changes to the PHP ini file, as the changes may not be reflected otherwise.
Inserting data into the middle of a text file is not a simple task. If possible, you should append it to the end of your file.
The easiest way to append data some text file is to use build-in fs.appendFile(filename, data[, options], callback)
function from fs
module:
var fs = require('fs')
fs.appendFile('log.txt', 'new data', function (err) {
if (err) {
// append failed
} else {
// done
}
})
But if you want to write data to log file several times, then it'll be best to use fs.createWriteStream(path[, options])
function instead:
var fs = require('fs')
var logger = fs.createWriteStream('log.txt', {
flags: 'a' // 'a' means appending (old data will be preserved)
})
logger.write('some data') // append string to your file
logger.write('more data') // again
logger.write('and more') // again
Node will keep appending new data to your file every time you'll call .write
, until your application will be closed, or until you'll manually close the stream calling .end
:
logger.end() // close string
Theres no shorthand way in vue 2.
Jeff's method seems already deprecated in vue 2.
Heres another way u can achieve your goal.
var app = new Vue({_x000D_
el:'#app',_x000D_
methods: { _x000D_
showMyDiv() {_x000D_
console.log(this.$refs.myDiv);_x000D_
}_x000D_
}_x000D_
_x000D_
});
_x000D_
<script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/vue.js"></script>_x000D_
<div id='app'>_x000D_
<div id="myDiv" ref="myDiv"></div>_x000D_
<button v-on:click="showMyDiv" >Show My Div</button>_x000D_
</div>

Looks like the solution as.numeric(levels(f))[f] no longer work with R 4.0.
Alternative solution:
factor2number <- function(x){
data.frame(levels(x), 1:length(levels(x)), row.names = 1)[x, 1]
}
factor2number(yourFactor)
I've just started using OSX. Free editors of note that I've discovered:
Double precision means the numbers takes twice the word-length to store. On a 32-bit processor, the words are all 32 bits, so doubles are 64 bits. What this means in terms of performance is that operations on double precision numbers take a little longer to execute. So you get a better range, but there is a small hit on performance. This hit is mitigated a little by hardware floating point units, but its still there.
The N64 used a MIPS R4300i-based NEC VR4300 which is a 64 bit processor, but the processor communicates with the rest of the system over a 32-bit wide bus. So, most developers used 32 bit numbers because they are faster, and most games at the time did not need the additional precision (so they used floats not doubles).
All three systems can do single and double precision floating operations, but they might not because of performance. (although pretty much everything after the n64 used a 32 bit bus so...)
modify() in your example is a private function, that won't be accessible from anywhere but within your A, B or C definition. You would need to declare it as
this.modify = function(){}
C has no reference to its parents, unless you pass it to C. If C is set up to inherit from A or B, it will inherit its public methods (not its private functions like you have modify() defined). Once C inherits methods from its parent, you can override the inherited methods.
well if you really need a curl equivalent you can try node-curl
npm install node-curl
you will probably need to add libcurl4-gnutls-dev
.
You just need to provide an alias for your aggregate columns in the CTE
d as (SELECT
duration,
sum(totalitems) as sumtotalitems
FROM
[DrySoftBranch].[dbo].[mnthItemWiseTotalQty] ('1') AS BkdQty
group by duration
)
Using just simple loops:
public static void compareSortOrder (List<String> sortOrder, List<String> listToCompare){
int currentSortingLevel = 0;
for (int i=0; i<listToCompare.size(); i++){
System.out.println("Item from list: " + listToCompare.get(i));
System.out.println("Sorting level: " + sortOrder.get(currentSortingLevel));
if (listToCompare.get(i).equals(sortOrder.get(currentSortingLevel))){
} else {
try{
while (!listToCompare.get(i).equals(sortOrder.get(currentSortingLevel)))
currentSortingLevel++;
System.out.println("Changing sorting level to next value: " + sortOrder.get(currentSortingLevel));
} catch (ArrayIndexOutOfBoundsException e){
}
}
}
}
And sort order in List
public static List<String> ALARMS_LIST = Arrays.asList(
"CRITICAL",
"MAJOR",
"MINOR",
"WARNING",
"GOOD",
"N/A");
This will get you pretty close, and I use it in production and have never had a collision. However, if you look at the constructor for a guid in reflector, you will see all of the checks it makes.
public static bool GuidTryParse(string s, out Guid result)
{
if (!String.IsNullOrEmpty(s) && guidRegEx.IsMatch(s))
{
result = new Guid(s);
return true;
}
result = default(Guid);
return false;
}
static Regex guidRegEx = new Regex("^[A-Fa-f0-9]{32}$|" +
"^({|\\()?[A-Fa-f0-9]{8}-([A-Fa-f0-9]{4}-){3}[A-Fa-f0-9]{12}(}|\\))?$|" +
"^({)?[0xA-Fa-f0-9]{3,10}(, {0,1}[0xA-Fa-f0-9]{3,6}){2}, {0,1}({)([0xA-Fa-f0-9]{3,4}, {0,1}){7}[0xA-Fa-f0-9]{3,4}(}})$", RegexOptions.Compiled);
You can change from info.plist having attribute "Bundle Name" .
The following is Peter Lyons' answer verbatim, ported over to vanilla JS from Coffeescript, as requested by several others. Peter's answer is very able, and anyone voting on my answer should vote on his as well.
Config
What you are doing is fine. I like to have my own config namespace set up in a top-level config.js
file with a nested namespace like this.
// Set the current environment to true in the env object
var currentEnv = process.env.NODE_ENV || 'development';
exports.appName = "MyApp";
exports.env = {
production: false,
staging: false,
test: false,
development: false
};
exports.env[currentEnv] = true;
exports.log = {
path: __dirname + "/var/log/app_#{currentEnv}.log"
};
exports.server = {
port: 9600,
// In staging and production, listen loopback. nginx listens on the network.
ip: '127.0.0.1'
};
if (currentEnv != 'production' && currentEnv != 'staging') {
exports.enableTests = true;
// Listen on all IPs in dev/test (for testing from other machines)
exports.server.ip = '0.0.0.0';
};
exports.db {
URL: "mongodb://localhost:27017/#{exports.appName.toLowerCase()}_#{currentEnv}"
};
This is friendly for sysadmin editing. Then when I need something, like the DB connection info, it`s
require('./config').db.URL
Routes/Controllers
I like to leave my routes with my controllers and organize them in an app/controllers
subdirectory. Then I can load them up and let them add whatever routes they need.
In my app/server.js
javascript file I do:
[
'api',
'authorization',
'authentication',
'domains',
'users',
'stylesheets',
'javascripts',
'tests',
'sales'
].map(function(controllerName){
var controller = require('./controllers/' + controllerName);
controller.setup(app);
});
So I have files like:
app/controllers/api.js
app/controllers/authorization.js
app/controllers/authentication.js
app/controllers/domains.js
And for example in my domains controller, I have a setup
function like this.
exports.setup = function(app) {
var controller = new exports.DomainController();
var route = '/domains';
app.post(route, controller.create);
app.put(route, api.needId);
app.delete(route, api.needId);
route = '/domains/:id';
app.put(route, controller.loadDomain, controller.update);
app.del(route, controller.loadDomain, function(req, res){
res.sendJSON(req.domain, status.OK);
});
}
Views
Putting views in app/views
is becoming the customary place. I lay it out like this.
app/views/layout.jade
app/views/about.jade
app/views/user/EditUser.jade
app/views/domain/EditDomain.jade
Static Files
Go in a public
subdirectory.
Github/Semver/NPM
Put a README.md markdown file at your git repo root for github.
Put a package.json file with a semantic version number in your git repo root for NPM.
If we need only one column to be numeric
yyz$b <- as.numeric(as.character(yyz$b))
But, if all the columns needs to changed to numeric
, use lapply
to loop over the columns and convert to numeric
by first converting it to character
class as the columns were factor
.
yyz[] <- lapply(yyz, function(x) as.numeric(as.character(x)))
Both the columns in the OP's post are factor
because of the string "n/a"
. This could be easily avoided while reading the file using na.strings = "n/a"
in the read.table/read.csv
or if we are using data.frame
, we can have character
columns with stringsAsFactors=FALSE
(the default is stringsAsFactors=TRUE
)
Regarding the usage of apply
, it converts the dataset to matrix
and matrix
can hold only a single class. To check the class
, we need
lapply(yyz, class)
Or
sapply(yyz, class)
Or check
str(yyz)
You can accomplish what you want with either:
docker run -t -d <image-name>
or
docker run -i -d <image-name>
or
docker run -it -d <image-name>
The command parameter as suggested by other answers (i.e. tail -f /dev/null) is completely optional, and is NOT required to get your container to stay running in the background.
Also note the Docker documentation suggests that combining -i and -t options will cause it to behave like a shell.
See:
I was developing for .NET core 2.1 using log4net 2.0.8 and found NealWalters code moans about 0 arguments for XmlConfigurator.Configure(). I found a solution by Matt Watson here
log4net.GlobalContext.Properties["LogFileName"] = @"E:\\file1"; //log file path
var logRepository = LogManager.GetRepository(Assembly.GetEntryAssembly());
XmlConfigurator.Configure(logRepository, new FileInfo("log4net.config"));
Use (localdb)\MSSQLLocalDB
. That is the LocalDB instance intended for applications, independent of Visual Studio version.
Disregard my original answer: "With SQL Server 2014 Express LocalDB, use (localdb)\ProjectsV12
. This works in both Visual Studio 2013 and SQL Server 2014 Management Studio." While ProjectsV12 will indeed give you a LocalDB instance, it's the wrong one, intended for use by SQL Server Data Tools.
I know this is old, but i think i have good solution. Comparing to other answers and also comparing to accepted, mine accepts multiple values. Basically filter object with key:value search parameters (also object within object). Also it works with numbers etc, cause when comparing, it converts them to string.
import { Pipe, PipeTransform } from '@angular/core';
@Pipe({name: 'filter'})
export class Filter implements PipeTransform {
transform(array: Array<Object>, filter: Object): any {
let notAllKeysUndefined = false;
let newArray = [];
if(array.length > 0) {
for (let k in filter){
if (filter.hasOwnProperty(k)) {
if(filter[k] != undefined && filter[k] != '') {
for (let i = 0; i < array.length; i++) {
let filterRule = filter[k];
if(typeof filterRule === 'object') {
for(let fkey in filterRule) {
if (filter[k].hasOwnProperty(fkey)) {
if(filter[k][fkey] != undefined && filter[k][fkey] != '') {
if(this.shouldPushInArray(array[i][k][fkey], filter[k][fkey])) {
newArray.push(array[i]);
}
notAllKeysUndefined = true;
}
}
}
} else {
if(this.shouldPushInArray(array[i][k], filter[k])) {
newArray.push(array[i]);
}
notAllKeysUndefined = true;
}
}
}
}
}
if(notAllKeysUndefined) {
return newArray;
}
}
return array;
}
private shouldPushInArray(item, filter) {
if(typeof filter !== 'string') {
item = item.toString();
filter = filter.toString();
}
// Filter main logic
item = item.toLowerCase();
filter = filter.toLowerCase();
if(item.indexOf(filter) !== -1) {
return true;
}
return false;
}
}
If you know what you are doing, another way is simply find the file that warns you(the path of the file is shown in warning info), comment the lines that generate the warnings.
You want a parameter source:
Set<Integer> ids = ...;
MapSqlParameterSource parameters = new MapSqlParameterSource();
parameters.addValue("ids", ids);
List<Foo> foo = getJdbcTemplate().query("SELECT * FROM foo WHERE a IN (:ids)",
parameters, getRowMapper());
This only works if getJdbcTemplate()
returns an instance of type NamedParameterJdbcTemplate
The best way is to use menu mnemonics, i.e. to have menu entries in your main form that get assigned the keyboard shortcut you want. Then everything else is handled internally and all you have to do is to implement the appropriate action that gets executed in the Click
event handler of that menu entry.
Please run the following commands to do the fix. After running python3 -m pip install --upgrade pip
, please run the following command.
hash -r pip
def test():
r1 = 1
r2 = 2
r3 = 3
return r1, r2, r3
x,y,z = test()
print x
print y
print z
> test.py

In my case it was a missing SPN, had to run these two commands:
setspn -a MSSQLSvc:SERVERNAME SERVERNAME setspn -a MSSQLSvc:SERVERNAME:1433 SERVERNAME
In other words in my case I had the FQDN in there already correctly but not just the NETBIOS name, after adding these it worked fine. Well initially it didn't but after waiting 2 minutes it did.
Add the following to the top of your file # coding=utf-8
If you go to the link in the error you can seen the reason why:
Defining the Encoding
Python will default to ASCII as standard encoding if no other encoding hints are given. To define a source code encoding, a magic comment must be placed into the source files either as first or second line in the file, such as: # coding=
Please don't use techniques described in other answers here. They are either not working with css3 animations size changes, floating layout changes or changes that don't come from jQuery land. You can use a resize-detector, a event-based approach, that doesn't waste your CPU time.
https://github.com/marcj/css-element-queries
It contains a ResizeSensor class you can use for that purpose.
new ResizeSensor(jQuery('#mainContent'), function(){
console.log('main content dimension changed');
});
Disclaimer: I wrote this library
EDIT: Now you can use docker exec -it "id of running container" bash
(doc)
Previously, the answer to this question was:
If you really must and you are in a debug environment, you can do this: sudo lxc-attach -n <ID>
Note that the id needs to be the full one (docker ps -notrunc
).
However, I strongly recommend against this.
notice: -notrunc
is deprecated, it will be replaced by --no-trunc
soon.
You can simply specify a series of images like this:
\includegraphics<1>{A}
\includegraphics<2>{B}
\includegraphics<3>{C}
This will produce three slides with the images A to C in exactly the same position.
The simplest solution to run two Python processes concurrently is to run them from a bash file, and tell each process to go into the background with the &
shell operator.
python script1.py &
python script2.py &
For a more controlled way to run many processes in parallel, look into the Supervisor project, or use the multiprocessing module to orchestrate from inside Python.
GTK3:

from gi.repository import Gtk, Gdk
class Hello(Gtk.Window):
def __init__(self):
super(Hello, self).__init__()

clipboard.set_text("hello world", -1)
Gtk.main_quit()
def main():

Depending on the use case, this could be useful. It cuts all text either side of the flags:
b = "This is a string used for testing"
--Removes unwanted text
c = (b:match("a([^/]+)used"))

git checkout BranchB
git merge BranchA
git push origin BranchB
This is all if you intend to not merge your changes back to master. Generally it is a good practice to merge all your changes back to master, and create new branches off of that.
Also, after the merge command, you will have some conflicts, which you will have to edit manually and fix.
Make sure you are in the branch where you want to copy all the changes to. git merge
will take the branch you specify and merge it with the branch you are currently in.
Suppose an autofac setting like the following:
public class AutofacContractResolver : DefaultContractResolver
{
private readonly IContainer _container;
public AutofacContractResolver(IContainer container)
{
_container = container;
}
protected override JsonObjectContract CreateObjectContract(Type objectType)
{
JsonObjectContract contract = base.CreateObjectContract(objectType);
// use Autofac to create types that have been registered with it
if (_container.IsRegistered(objectType))
{
contract.DefaultCreator = () => _container.Resolve(objectType);
}
return contract;
}
}
Then, suppose your class is like this:
public class TaskController
{
private readonly ITaskRepository _repository;
private readonly ILogger _logger;
public TaskController(ITaskRepository repository, ILogger logger)
{
_repository = repository;
_logger = logger;
}
public ITaskRepository Repository
{
get { return _repository; }
}
public ILogger Logger
{
get { return _logger; }
}
}
Therefore, the usage of the resolver in deserialization could be like:
ContainerBuilder builder = new ContainerBuilder();
builder.RegisterType<TaskRepository>().As<ITaskRepository>();
builder.RegisterType<TaskController>();
builder.Register(c => new LogService(new DateTime(2000, 12, 12))).As<ILogger>();
IContainer container = builder.Build();
AutofacContractResolver contractResolver = new AutofacContractResolver(container);
string json = @"{
'Logger': {
'Level':'Debug'
}
}";
// ITaskRespository and ILogger constructor parameters are injected by Autofac
TaskController controller = JsonConvert.DeserializeObject<TaskController>(json, new JsonSerializerSettings
{
ContractResolver = contractResolver
});
Console.WriteLine(controller.Repository.GetType().Name);
You can see more details in http://www.newtonsoft.com/json/help/html/DeserializeWithDependencyInjection.htm
Because of the way jQuery selectors are evaluated right-to-left, the quite readable li:not(:first)
is slowed down by that evaluation.
An equally fast and easy to read solution is using the function version .not(":first")
:
e.g.
$("li").not(":first").hide();
JSPerf: http://jsperf.com/fastest-way-to-select-all-expect-the-first-one/6
This is only few percentage points slower than slice(1)
, but is very readable as "I want all except the first one".
You could iterate on a copy (clone) of your original list:
List<String> copy = new ArrayList<String>(list);
for (String s : copy) {
// And if you have to add an element to the list, add it to the original one:
list.add("some element");
}
Note that it is not even possible to add a new element to a list while iterating on it, because it will result in a ConcurrentModificationException
.
In short Scripting languages have the following properties:
Eg.:Javascript,python,VBA.
This is the easy way:
---
- name: Create user
user: name=user shell=/bin/bash home=/srv/user groups=admin,sudo generate_ssh_key=yes ssh_key_bits=2048
- name: Set password to user
shell: echo user:plain_text_password | sudo chpasswd
no_log: True
You can also choose to break explicitly in code:
// Assuming C#
if (condition)
{
System.Diagnostics.Debugger.Break();
}
From MSDN:
Debugger.Break: If no debugger is attached, users are asked if they want to attach a debugger. If yes, the debugger is started. If a debugger is attached, the debugger is signaled with a user breakpoint event, and the debugger suspends execution of the process just as if a debugger breakpoint had been hit.
This is only a fallback, though. Setting a conditional breakpoint in Visual Studio, as described in other comments, is a better choice.
This works for me:
git pull origin <sha>
e.g.
[dbn src]$ git fetch
[dbn src]$ git status
On branch current_feature
Your branch and 'origin/master' have diverged,
and have 2 and 7 different commits each, respectively.
...
[dbn src]$ git log -3 --pretty=oneline origin/master
f4d10ad2a5eda447bea53fed0b421106dbecea66 CASE-ID1: some descriptive msg
28eb00a42e682e32bdc92e5753a4a9c315f62b42 CASE-ID2: I'm so good at writing commit titles
ff39e46b18a66b21bc1eed81a0974e5c7de6a3e5 CASE-ID2: woooooo
[dbn src]$ git pull origin 28eb00a42e682e32bdc92e5753a4a9c315f62b42
[dbn src]$ git status
On branch current_feature
Your branch and 'origin/master' have diverged,
and have 2 and 1 different commits each, respectively.
...
This pulls 28eb00, ff39e4, and everything before, but doesn't pull f4d10ad. It allows the use of pull --rebase, and honors pull settings in your gitconfig. This works because you're basically treating 28eb00 as a branch.
For the version of git that I'm using, this method requires a full commit hash - no abbreviations or aliases are allowed. You could do something like:
[dbn src]$ git pull origin `git rev-parse origin/master^`
Below are scripts for emptying and deleting a Kafka topic assuming localhost as the zookeeper server and Kafka_Home is set to the install directory:

To fully delete topics you must stop any applicable kafka broker(s) and remove it's directory(s) from the kafka log dir (default: /tmp/kafka-logs) and then run this script to remove the topic from zookeeper. To verify it's been deleted from zookeeper the output of ls /brokers/topics should no longer include the topic:
#!/bin/bash
echo "Enter name of topic to delete from zookeeper:"
read topicName
/$Kafka_Home/bin/zookeeper-shell localhost:2181 <<EOF
rmr /brokers/topics/$topicName
ls /brokers/topics
quit

To call the function on click of some html element (control).
$('#controlID').click(myFunction);
You will need to ensure you bind the event when your html element is ready on which you binding the event. You can put the code in document.ready
$(document).ready(function(){
$('#controlID').click(myFunction);
});
You can use anonymous function to bind the event to the html element.
$(document).ready(function(){
$('#controlID').click(function(){
$.messager.show({
title:'My Title',
msg:'The message content',
showType:'fade',
style:{
right:'',
bottom:''
}
});
});
});
If you want to bind click with many elements you can use class selector
$('.someclass').click(myFunction);
Edit based on comments by OP, If you want to call function under some condition
You can use if for conditional execution, for example,
if(a == 3)
myFunction();
If you are using an http proxy server, revise the following proxy settings in "gradle.properties" file in your project's root folder. If not using proxy server, just delete those entries.
systemProp.http.proxyPort=8080
systemProp.http.proxyUser=UserName
systemProp.http.proxyPassword=Passw0rd
systemProp.https.proxyPassword=Passw0rd
systemProp.https.proxyHost=proxy.abc.com
systemProp.http.proxyHost=proxy.abc.com
systemProp.https.proxyPort=8080
systemProp.https.proxyUser=UserName
GIFs store colors as one of x number of possible colors in a palette. Read about the gif limited color palette. So PIL is giving you the palette index, rather than the color information of that palette color.
Edit: Removed link to a blog post solution that had a typo. Other answers do the same thing without the typo.
Try installing it again with the stand alone installer https://software.intel.com/en-us/android/articles/intel-hardware-accelerated-execution-manager-end-user-license-agreement - assuming you have a CPU that supports Virtualization, have turned off antivirus and any hypervisor.
From Perlfaq8:
You're confusing the purpose of system() and backticks (``). system() runs a command and returns exit status information (as a 16 bit value: the low 7 bits are the signal the process died from, if any, and the high 8 bits are the actual exit value). Backticks (``) run a command and return what it sent to STDOUT.
$exit_status = system("mail-users");
$output_string = `ls`;
There are many ways to execute external commands from Perl. The most commons with their meanings are:
If you use an extension, there is no need to subclass UITextField and the new functionality will be made available to any UITextField in your app:
extension UITextField {
func setLeftPaddingPoints(_ amount:CGFloat){
let paddingView = UIView(frame: CGRect(x: 0, y: 0, width: amount, height: self.frame.size.height))
self.leftView = paddingView
self.leftViewMode = .always
}
func setRightPaddingPoints(_ amount:CGFloat) {
let paddingView = UIView(frame: CGRect(x: 0, y: 0, width: amount, height: self.frame.size.height))
self.rightView = paddingView
self.rightViewMode = .always
}
}
When I need to set the padding of a text field anywhere in my application, I simply do the following:
textField.setLeftPaddingPoints(10)
textField.setRightPaddingPoints(10)
Using Swift extensions, the functionality is added to the UITextField directly without subclassing.
Hope this helps!
You can just forgo the quotes for alphanumeric attributes:
echo "<font color=red> XHTML is not a thing anymore. </font>";
echo "<div class=editorial-note> There, I said it. </div>";
Is perfectly valid in HTML, and though still shunned, absolutely en vogue since HTML5.
CAVEATS
htmlspecialchars
or some whitelisting).<font>
specifically is somewhat outdated however.For Ionic, try this:
ionic cordova plugin add cordova-plugin-androidx
ionic cordova plugin add cordova-plugin-androidx-adapter
The error comes because this app is not using androidX but these plugins solve errors.
Here is a list of all unicode emoji's available:
https://en.wikipedia.org/wiki/Emoji#Unicode_blocks
Example:
echo -e "\U1F304"
For get the ASCII value of this character use hexdump
echo -e "" | hexdump -C
00000000 f0 9f 8c 84 0a |.....|
00000005
And then use the values informed in hex format
echo -e "\xF0\x9F\x8C\x84\x0A"
With this command you will see all changes in the repository path/to/repo
that were committed in revision <revision>
:
svn diff -c <revision> path/to/repo
The -c
indicates that you would like to look at a changeset, but there are many other ways you can look at diffs and changesets. For example, if you would like to know which files were changed (but not how), you can issue
svn log -v -r <revision>
Or, if you would like to show at the changes between two revisions (and not just for one commit):
svn diff -r <revA>:<revB> path/to/repo
Use mktemp -d
. It creates a temporary directory with a random name and makes sure that file doesn't already exist. You need to remember to delete the directory after using it though.
Since variable names in the BASH shell cannot contain a dot or space it is better to use an associative array in BASH like this:
#!/bin/bash
# declare an associative array
declare -A arr
# read file line by line and populate the array. Field separator is "="
while IFS='=' read -r k v; do
arr["$k"]="$v"
done < app.properties
Testing:
Use declare -p to show the result:
> declare -p arr
declare -A arr='([db.uat.passwd]="secret" [db.uat.user]="saple user" )'
Here's the complete solution if you want to implement the wifi hotspot feature programmatically in your android app.
SOLUTION FOR API < 26:
For devices < API 26. There is no public API by Android for this purpose. So, in order to work with those APIs you've to access private APIs through reflection. It is not recommended but if you've no other options left, then here's a trick.
First of all, you need to have this permission in your manifest,
<uses-permission
android:name="android.permission.WRITE_SETTINGS"
tools:ignore="ProtectedPermissions"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE"/>
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>
Here's how you can ask it on run-time:
private boolean showWritePermissionSettings() {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M
&& Build.VERSION.SDK_INT < Build.VERSION_CODES.O) {
if (!Settings.System.canWrite(this)) {
Log.v("DANG", " " + !Settings.System.canWrite(this));
Intent intent = new Intent(android.provider.Settings.ACTION_MANAGE_WRITE_SETTINGS);
intent.setData(Uri.parse("package:" + this.getPackageName()));
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
this.startActivity(intent);
return false;
}
}
return true; //Permission already given
}
You can then access the setWifiEnabled
method through reflection. This returns true if the action you asked for is being process correctly i.e. enabling/disabling hotspot.
public boolean setWifiEnabled(WifiConfiguration wifiConfig, boolean enabled) {
WifiManager wifiManager;
try {
if (enabled) { //disables wifi hotspot if it's already enabled
wifiManager.setWifiEnabled(false);
}
Method method = wifiManager.getClass()
.getMethod("setWifiApEnabled", WifiConfiguration.class, boolean.class);
return (Boolean) method.invoke(wifiManager, wifiConfig, enabled);
} catch (Exception e) {
Log.e(this.getClass().toString(), "", e);
return false;
}
}
You can also get the wificonfiguration of your hotspot through reflection. I've answered that method for this question on StackOverflow.
P.S: If you don't want to turn on hotspot programmatically, you can start this intent and open the wifi settings screen for user to turn it on manually.
SOLUTION FOR API >= 26:
Finally, android released an official API for versions >= Oreo. You can just use the public exposed API by android i.e. startLocalOnlyHotspot
It turns on a local hotspot without internet access. Which thus can be used to host a server or transfer files.
It requires Manifest.permission.CHANGE_WIFI_STATE
and ACCESS_FINE_LOCATION
permissions.
Here's a simple example of how you can turn on hotspot using this API.
private WifiManager wifiManager;
WifiConfiguration currentConfig;
WifiManager.LocalOnlyHotspotReservation hotspotReservation;
The method to turn on hotspot:
@RequiresApi(api = Build.VERSION_CODES.O)
public void turnOnHotspot() {
wifiManager.startLocalOnlyHotspot(new WifiManager.LocalOnlyHotspotCallback() {
@Override
public void onStarted(WifiManager.LocalOnlyHotspotReservation reservation) {
super.onStarted(reservation);
hotspotReservation = reservation;
currentConfig = hotspotReservation.getWifiConfiguration();
Log.v("DANG", "THE PASSWORD IS: "
+ currentConfig.preSharedKey
+ " \n SSID is : "
+ currentConfig.SSID);
hotspotDetailsDialog();
}
@Override
public void onStopped() {
super.onStopped();
Log.v("DANG", "Local Hotspot Stopped");
}
@Override
public void onFailed(int reason) {
super.onFailed(reason);
Log.v("DANG", "Local Hotspot failed to start");
}
}, new Handler());
}
`
Here's how you can get details of the locally created hotspot
private void hotspotDetaisDialog()
{
Log.v(TAG, context.getString(R.string.hotspot_details_message) + "\n" + context.getString(
R.string.hotspot_ssid_label) + " " + currentConfig.SSID + "\n" + context.getString(
R.string.hotspot_pass_label) + " " + currentConfig.preSharedKey);
}
If it throws, a security exception even after giving the required permissions then you should try enabling your location using GPS. Here's the solution.
Recently, I've developed a demo app called Spotserve. That turns on wifi hotspot for all devices with API>=15 and hosts a demo server on that hotspot. You can check that for more details. Hope this helps!
SELECT *
FROM (
SELECT q.*, rownum rn
FROM (
SELECT *
FROM maps006
ORDER BY
id
) q
)
WHERE rn BETWEEN 50 AND 100
Note the double nested view. ROWNUM
is evaluated before ORDER BY
, so it is required for correct numbering.
If you omit ORDER BY
clause, you won't get consistent order.
I tried your code, you didn't assign/bind a value to your formControlName.
In HTML file:
<form [formGroup]="form">
<label>
<input type="radio" value="Male" formControlName="gender">
<span>male</span>
</label>
<label>
<input type="radio" value="Female" formControlName="gender">
<span>female</span>
</label>
</form>
In the TS file:
form: FormGroup;
constructor(fb: FormBuilder) {
this.name = 'Angular2'
this.form = fb.group({
gender: ['', Validators.required]
});
}
Make sure you use Reactive form properly: [formGroup]="form"
and you don't need the name attribute.
In my sample. words male
and female
in span tags are the values display along the radio button and Male
and Female
values are bind to formControlName
To make it shorter:
<form [formGroup]="form">
<input type="radio" value='Male' formControlName="gender" >Male
<input type="radio" value='Female' formControlName="gender">Female
</form>
Hope it helps:)
2A. As far as last seven days have much less rows than whole table an index can help
2B. If you are interested only in Created_Date you can try using some group by and count, it should help with the result set size
You can use the DataFrame head and tail methods as syntactic sugar instead of slicing/loc here. I use a split size of 3; for your example use headSize=10
def split(df, headSize) :
hd = df.head(headSize)
tl = df.tail(len(df)-headSize)
return hd, tl
df = pd.DataFrame({ 'A':[2,4,6,8,10,2,4,6,8,10],
'B':[10,-10,0,20,-10,10,-10,0,20,-10],
'C':[4,12,8,0,0,4,12,8,0,0],
'D':[9,10,0,1,3,np.nan,np.nan,np.nan,np.nan,np.nan]})
# Split dataframe into top 3 rows (first) and the rest (second)
first, second = split(df, 3)
TL;DR: check if you can read/write to /dev/tty
. If no and you have used su
to open the shell, check if you have used it correctly.

git-remote-https
tries to read credentials via /dev/tty
so I tested if it works:
$ echo ahoj > /dev/tty
bash: /dev/tty: No such device or address
But in another terminal:
# echo ahoj > /dev/tty
ahoj
I knew I switched to this user using su
so I exited the shell to see how and found out I used command su danman -
so I tested it again:
~# su danman -
bash: cannot set terminal process group (-1): Inappropriate ioctl for device
bash: no job control in this shell
/root$ echo ahoj > /dev/tty
bash: /dev/tty: No such device or address
I probably ignored the message and continued working but this was the reason.
When I switched using the correct su - danman
everything worked fine:
~# su - danman
danman@speedy:~$ echo ahoj > /dev/tty
ahoj
After this, git started working correctly
Looks like you're trying to both inherit the groupId from the parent, and simultaneously specify the parent using an inherited groupId!
In the child pom, use something like this:
<modelVersion>4.0.0</modelVersion>
<parent>
<groupId>org.felipe</groupId>
<artifactId>tutorial_maven</artifactId>
<version>1.0-SNAPSHOT</version>
<relativePath>../pom.xml</relativePath>
</parent>
<artifactId>tutorial_maven_jar</artifactId>
Using properties like ${project.groupId}
won't work there. If you specify the parent in this way, then you can inherit the groupId and version in the child pom. Hence, you only need to specify the artifactId in the child pom.
Maybe?

This has gotten a good answer but decided to expand a bit:
You can't get your application accepted to AppStore without reading Apple's iOS Human Interface Guidelines well. (they retain the right to reject you for doing anything against them) The section "Don't Quit Programmatically" http://developer.apple.com/library/ios/#DOCUMENTATION/UserExperience/Conceptual/MobileHIG/UEBestPractices/UEBestPractices.html is an exact guideline in how you should treat in this case.
If you ever have a problem with Apple platform you can't easily find a solution for, consult HIG. It's possible Apple simply doesn't want you to do it and they usually (I'm not Apple so I can't guarantee always) do say so in their documentation.

Eclipse can't work out what you want to run and since you've not run anything before, it can't try re-running that either.
Instead of clicking the green 'run' button, click the dropdown next to it and chose Run Configurations. On the Android tab, make sure it's set to your project. In the Target tab, set the tick box and options as appropriate to target your device. Then click Run. Keep an eye on your Console tab in Eclipse - that'll let you know what's going on. Once you've got your run configuration set, you can just hit the green 'run' button next time.
Sometimes getting everything to talk to your device can be problematic to begin with. Consider using an AVD (i.e. an emulator) as alternative, at least to begin with if you have problems. You can easily create one from the menu Window -> Android Virtual Device Manager within Eclipse.
To view the progress of your project being installed and started on your device, check the console. It's a panel within Eclipse with the tabs Problems/Javadoc/Declaration/Console/LogCat etc. It may be minimised - check the tray in the bottom right. Or just use Window/Show View/Console from the menu to make it come to the front. There are two consoles, Android and DDMS - there is a dropdown by its icon where you can switch.
How about this?
=IF(ISERROR(MATCH(A1,B:B, 0)), "No Match", INDIRECT(ADDRESS(MATCH(A1,B:B, 0), 3)))
The "3" at the end means for column C.
I would go with Lev, but it's worth pointing out that if you end up with more complex searches that using re.finditer may be worth bearing in mind (but re's often cause more trouble than worth - but sometimes handy to know)
test = "ooottat"
[ (i.start(), i.end()) for i in re.finditer('o', test)]
# [(0, 1), (1, 2), (2, 3)]
[ (i.start(), i.end()) for i in re.finditer('o+', test)]
# [(0, 3)]
Who says a file name needs an extension?? take a look on a *nix machine sometime...
I agree with your friend, no trailing slash.
First line in the List API says it is an ordered collection (also known as a sequence). If you sort the list you can't maintain the order, so there is no TreeList in Java.
As API says Java List got inspired from Sequence and see the sequence properties http://en.wikipedia.org/wiki/Sequence_(mathematics)
It doesn't mean that you can't sort the list, but Java strict to his definition and doesn't provide sorted versions of lists by default.
no one says that you also have to have mod_headers enabled, so if still not working, try this:
(following tips works on Ubuntu, don't know about other distributions)
you can check list of loaded modules with
apache2ctl -M
to enable mod_headers you can use
a2enmod headers
of course after any changes in Apache you have to restart it:
/etc/init.d/apache2 restart
Then you can use
<IfModule mod_headers.c>
Header set Access-Control-Allow-Origin "*"
</IfModule>
And if mod_headers is not active, this line will do nothing at all. You can try skip if clause and just add Header set Access-Control-Allow-Origin "*"
in your config, then it should throw error during start if mod_headers is not active.
You can't do it using environment variables. It's done via "non standard" options. Run: java -X
for details. The options you're looking for are -Xmx
and -Xms
(this is "initial" heap size, so probably what you're looking for.)
The solution of using a list of axes by abevieiramota works very well until you use only one row of images, as pointed out in the comments. Using a reasonable aspect ratio for figsize
helps, but is still far from perfect. For example:
import numpy as np
import matplotlib.pyplot as plt
fig, axes = plt.subplots(nrows=1, ncols=3, figsize=(9.75, 3))
for ax in axes.flat:
im = ax.imshow(np.random.random((10,10)), vmin=0, vmax=1)
fig.colorbar(im, ax=axes.ravel().tolist())
plt.show()
The colorbar function provides the shrink
parameter which is a scaling factor for the size of the colorbar axes. It does require some manual trial and error. For example:
fig.colorbar(im, ax=axes.ravel().tolist(), shrink=0.75)
Try this solution:
Oz<-subset(data, data$Month==5,select=Ozone) # select ozone value in the month of
#May (i.e. Month = 5)
summary(T) #gives caracteristics of table( contains 1 column of Ozone) including max, min ...
This worked for me in swift:
let dirPaths = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)
println("App Path: \(dirPaths)")
You can use the getText() method anywhere in your code it is instancely called by your object, So you can use the method anywhere within a calass
-Xmx1024m -XX:MaxPermSize=512m -Xms512m
Add this parameter as argument in your server params
I would argue that there is a better method, by setting the scope of the variable $MyInvocation.MyCommand.Path:
ex> $script:MyInvocation.MyCommand.Name
This method works in all circumstances of invocation:
EX: Somescript.ps1
function printme () {
"In function:"
( "MyInvocation.ScriptName: " + [string]($MyInvocation.ScriptName) )
( "script:MyInvocation.MyCommand.Name: " + [string]($script:MyInvocation.MyCommand.Name) )
( "MyInvocation.MyCommand.Name: " + [string]($MyInvocation.MyCommand.Name) )
}
"Main:"
( "MyInvocation.ScriptName: " + [string]($MyInvocation.ScriptName) )
( "script:MyInvocation.MyCommand.Name: " + [string]($script:MyInvocation.MyCommand.Name) )
( "MyInvocation.MyCommand.Name: " + [string]($MyInvocation.MyCommand.Name) )
" "
printme
exit
OUTPUT:
PS> powershell C:\temp\test.ps1
Main:
MyInvocation.ScriptName:
script:MyInvocation.MyCommand.Name: test.ps1
MyInvocation.MyCommand.Name: test.ps1
In function:
MyInvocation.ScriptName: C:\temp\test.ps1
script:MyInvocation.MyCommand.Name: test.ps1
MyInvocation.MyCommand.Name: printme
Notice how the above accepted answer does NOT return a value when called from Main. Also, note that the above accepted answer returns the full path when the question requested the script name only. The scoped variable works in all places.
Also, if you did want the full path, then you would just call:
$script:MyInvocation.MyCommand.Path
This is an example of "if else" with actions.
>>> def fun(num):
print 'This is %d' % num
>>> fun(10) if 10 > 0 else fun(2)
this is 10
OR
>>> fun(10) if 10 < 0 else 1

I had this problem.When I define firefox path my problem had been solved.
import webbrowser
urL='https://www.python.org'
mozilla_path="C:\\Program Files\\Mozilla Firefox\\firefox.exe"
webbrowser.register('firefox', None,webbrowser.BackgroundBrowser(mozilla_path))
webbrowser.get('firefox').open_new_tab(urL)
sudo mv /filename /etc/init.d/
sudo chmod +x /etc/init.d/filename
sudo update-rc.d filename defaults
Script should now start on boot. Note that this method also works with both hard links and symbolic links (ln
).
At this point in the boot process PATH isn't set yet, so it is critical that absolute paths are used throughout. BUT, as pointed out in the comments by Steve HHH, explicitly declaring the full file path (/etc/init.d/filename
) for the update-rc.d command is not valid in most versions of Linux. Per the manpage for update-rc.d, the second parameter is a script located in /etc/init.d/*
. Updated above code to reflect this.
Also as pointed out in the comments (by Charles Brandt), /filename
must be an init style script. A good template was also provided - https://github.com/fhd/init-script-template.
Another link to another article just to avoid possible link rot (although it would be saddening if GitHub died) - http://www.linux.com/learn/tutorials/442412-managing-linux-daemons-with-init-scripts
As pointed out in the comments (by Russell Yan), This works only on default mode of update-rc.d.
According to manual of update-rc.d, it can run on two modes, "the machines using the legacy mode will have a file /etc/init.d/.legacy-bootordering
", in which case you have to pass sequence and runlevel configuration through command line arguments.
The equivalent argument set for the above example is
sudo update-rc.d filename start 20 2 3 4 5 . stop 20 0 1 6 .
This error also comes if 2 versions of hamcrest-library or hamcrest-core is present in the classpath.
In the pom file, you can exclude the extra version and it works.
If all the previous answers didn't give any solution, you should check your user privileges.
If you could login as root
to mysql
then you should add this:
CREATE USER 'root'@'192.168.1.100' IDENTIFIED BY '***';
GRANT ALL PRIVILEGES ON * . * TO 'root'@'192.168.1.100' IDENTIFIED BY '***' WITH GRANT OPTION MAX_QUERIES_PER_HOUR 0 MAX_CONNECTIONS_PER_HOUR 0 MAX_UPDATES_PER_HOUR 0 MAX_USER_CONNECTIONS 0 ;
Then try to connect again using mysql -ubeer -pbeer -h192.168.1.100
. It should work.
Just for clarification: a table can have at most one primary key. A primary key consists of one or more columns (from that table). If a primary key consists of two or more columns it is called a composite primary key. It is defined as follows:
CREATE TABLE voting (
QuestionID NUMERIC,
MemberID NUMERIC,
PRIMARY KEY (QuestionID, MemberID)
);
The pair (QuestionID,MemberID) must then be unique for the table and neither value can be NULL. If you do a query like this:
SELECT * FROM voting WHERE QuestionID = 7
it will use the primary key's index. If however you do this:
SELECT * FROM voting WHERE MemberID = 7
it won't because to use a composite index requires using all the keys from the "left". If an index is on fields (A,B,C) and your criteria is on B and C then that index is of no use to you for that query. So choose from (QuestionID,MemberID) and (MemberID,QuestionID) whichever is most appropriate for how you will use the table.
If necessary, add an index on the other:
CREATE UNIQUE INDEX idx1 ON voting (MemberID, QuestionID);
While the other answer is correct, here's the fastest way to just go ahead and configure Meld as your visual diff tool. Just copy/paste this:
git config --global diff.tool meld
git config --global difftool.prompt false
Now run git difftool
in a directory and Meld will be launched for each different file.
Side note: Meld is surprisingly slow at comparing CSV files, and no Linux diff tool I've found is faster than this Windows tool called Compare It! (last updated in 2010).
Our global AsyncTask class variable
LongOperation LongOperationOdeme = new LongOperation();
And KEYCODE_BACK action which interrupt AsyncTask
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_BACK) {
LongOperationOdeme.cancel(true);
}
return super.onKeyDown(keyCode, event);
}
It works for me.
I found this maven
repo where you could download from directly a zip
file containing all the jars you need.
The solution I prefer is using Maven
, it is easy and you don't have to download each jar
alone. You can do it with the following steps:
Create an empty folder anywhere with any name you prefer, for example spring-source
Create a new file named pom.xml
Copy the xml below into this file
Open the spring-source
folder in your console
Run mvn install
After download finished, you'll find spring jars in /spring-source/target/dependencies
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

Also, if you need to download any other spring project, just copy the dependency
configuration from its corresponding web page.
For example, if you want to download Spring Web Flow
jars, go to its web page, and add its dependency
configuration to the pom.xml
dependencies
, then run mvn install
again.

As noted by others, bash
does not support floating point arithmetic, although you could fake it with some fixed decimal trickery, e.g. with two decimals:
echo $(( 100 * 1 / 3 )) | sed 's/..$/.&/'
Output:
.33

Stéphane Chazelas answered a similar question over on Unix.SX.
I took http://
out of my og:image
and replaced it with just plain old www.
then it started working fine.
You can use this tool, by Facebook to reset your image scrape cache and test what URL it is pulling for the demo image.
What worked for me :
$where = '';
/* $this->db->like('ust.title',$query_data['search'])
->or_like('usr.f_name',$query_data['search'])
->or_like('usr.l_name',$query_data['search']);*/
$where .= "(ust.title like '%".$query_data['search']."%'";
$where .= " or usr.f_name like '%".$query_data['search']."%'";
$where .= "or usr.l_name like '%".$query_data['search']."%')";
$this->db->where($where);
$datas = $this->db->join(TBL_USERS.' AS usr','ust.user_id=usr.id')
->where_in('ust.id', $blog_list)
->select('ust.*,usr.f_name as f_name,usr.email as email,usr.avatar as avatar, usr.sex as sex')
->get_where(TBL_GURU_BLOG.' AS ust',[
'ust.deleted_at' => NULL,
'ust.status' => 1,
]);
I have to do this to create a query like this :
SELECT `ust`.*, `usr`.`f_name` as `f_name`, `usr`.`email` as `email`, `usr`.`avatar` as `avatar`, `usr`.`sex` as `sex` FROM `blog` AS `ust` JOIN `users` AS `usr` ON `ust`.`user_id`=`usr`.`id` WHERE (`ust`.`title` LIKE '%mer%' ESCAPE '!' OR `usr`.`f_name` LIKE '%lok%' ESCAPE '!' OR `usr`.`l_name` LIKE '%mer%' ESCAPE '!') AND `ust`.`id` IN('36', '37', '38') AND `ust`.`deleted_at` IS NULL AND `ust`.`status` = 1 ;
var base_element = document.getElementById('__EXAMPLE_ELEMENT__');
for( var found_parent=base_element, i=100; found_parent.parentNode && !(found_parent=found_parent.parentNode).classList.contains('__CLASS_NAME__') && i>0; i-- );
console.log( found_parent );
There's another explanation for why .env
doesn't exist, and it happens when you move all the Laravel files.
Take this workflow: in your project directory you do laravel new whatever
, Laravel is installed in whatever
, you do mv * ..
to move all the files to your project folder, and you remove whatever
. The problem is, mv
doesn't move hidden files by default, so the .env
files are left behind, and are removed!
The ggrepel
package works great for repelling overlapping text labels away from each other. You can use either geom_label_repel()
(draws rectangles around the text) or geom_text_repel()
functions.

nba <- read.csv("http://datasets.flowingdata.com/ppg2008.csv", sep = ",")
nbaplot <- ggplot(nba, aes(x= MIN, y = PTS)) +
geom_point(color = "blue", size = 3)
### geom_label_repel
nbaplot +
geom_label_repel(aes(label = Name),
box.padding = 0.35,
point.padding = 0.5,
segment.color = 'grey50') +
theme_classic()
### geom_text_repel
# only label players with PTS > 25 or < 18
# align text vertically with nudge_y and allow the labels to
# move horizontally with direction = "x"
ggplot(nba, aes(x= MIN, y = PTS, label = Name)) +
geom_point(color = dplyr::case_when(nba$PTS > 25 ~ "#1b9e77",
nba$PTS < 18 ~ "#d95f02",
TRUE ~ "#7570b3"),
size = 3, alpha = 0.8) +
geom_text_repel(data = subset(nba, PTS > 25),
nudge_y = 32 - subset(nba, PTS > 25)$PTS,
size = 4,
box.padding = 1.5,
point.padding = 0.5,
force = 100,
segment.size = 0.2,
segment.color = "grey50",
direction = "x") +
geom_label_repel(data = subset(nba, PTS < 18),
nudge_y = 16 - subset(nba, PTS < 18)$PTS,

Suppose I have Hashmap with key datatype as KeyDataType and value datatype as ValueDataType
HashMap<KeyDataType,ValueDataType> list;
Add all items you needed to it. Now you can retrive all hashmap keys to a list by.
KeyDataType[] mKeys;
mKeys=list.keySet().toArray(new KeyDataType[list.size()]);
So, now you got your all keys in an array mkeys[]
you can now retrieve any value by calling
list.get(mkeys[position]);

In Objective-C, a selector's signature consists of:
Selectors have no knowledge of:
Here's a class implementation where performMethodsViaSelectors method performs the other class methods by way of selectors:
@implementation ClassForSelectors
- (void) fooNoInputs {
NSLog(@"Does nothing");
}
- (void) fooOneIput:(NSString*) first {
NSLog(@"Logs %@", first);
}
- (void) fooFirstInput:(NSString*) first secondInput:(NSString*) second {
NSLog(@"Logs %@ then %@", first, second);
}
- (void) performMethodsViaSelectors {
[self performSelector:@selector(fooNoInputs)];
[self performSelector:@selector(fooOneInput:) withObject:@"first"];
[self performSelector:@selector(fooFirstInput:secondInput:) withObject:@"first" withObject:@"second"];
}
@end
The method you want to create a selector for has a single input, so you would create a selector for it like so:
SEL myTestSelector = @selector(myTest:);
One approach (which I can't imagine is good programming practice) is to add the ...
which is traditionally used to pass arguments specified in one function to another.
> multiply <- function(a,b) a*b
> multiply(a = 2,b = 4,c = 8)
Error in multiply(a = 2, b = 4, c = 8) : unused argument(s) (c = 8)
> multiply2 <- function(a,b,...) a*b
> multiply2(a = 2,b = 4,c = 8)

Take a look at this article on Simple-talk.com by Pop Rivett. It walks you through creating a generic trigger that will log the OLDVALUE and the NEWVALUE for all updated columns. The code is very generic and you can apply it to any table you want to audit, also for any CRUD operation i.e. INSERT, UPDATE and DELETE. The only requirement is that your table to be audited should have a PRIMARY KEY (which most well designed tables should have anyway).
Here's the code relevant for your GUESTS Table.
