Uh, WHERE mydate<='2008-11-25'
is the way to do it. That should work.
Do you get an error message? Are you using an ancient version of MySQL?
Edit: The following works fine for me on MySQL 5.x
create temporary table foo(d datetime);
insert into foo(d) VALUES ('2000-01-01');
insert into foo(d) VALUES ('2001-01-01');
select * from foo where d <= '2000-06-01';
The spirit of handlebars is that it is "logicless". Sometimes this makes us feel like we are fighting with it, and sometimes we end up with ugly nested if/else logic. You could write a helper; many people augment handlebars with a "better" conditional operator or believe that it should be part of the core. I think, though, that instead of this,
{{#if FriendStatus.IsFriend}}
<div class="ui-state-default ui-corner-all" title=".ui-icon-mail-closed"><span class="ui-icon ui-icon-mail-closed"></span></div>
{{else}}
{{#if FriendStatus.FriendRequested}}
<div class="ui-state-default ui-corner-all" title=".ui-icon-check"><span class="ui-icon ui-icon-check"></span></div>
{{else}}
<div class="ui-state-default ui-corner-all" title=".ui-icon-plusthick"><span class="ui-icon ui-icon-plusthick"></span></div>
{{/if}}
{{/if}}
you might want to arrange things in your model so that you can have this,
{{#if is_friend }}
<div class="ui-state-default ui-corner-all" title=".ui-icon-mail-closed"><span class="ui-icon ui-icon-mail-closed"></span></div>
{{/if}}
{{#if is_not_friend_yet }}
<div class="ui-state-default ui-corner-all" title=".ui-icon-check"><span class="ui-icon ui-icon-check"></span></div>
{{/if}}
{{#if will_never_be_my_friend }}
<div class="ui-state-default ui-corner-all" title=".ui-icon-plusthick"><span class="ui-icon ui-icon-plusthick"></span></div>
{{/if}}
Just make sure that only one of these flags is ever true. Chances are, if you are using this if/elsif/else
in your view, you are probably using it somewhere else too, so these variables might not end up being superfluous.
Keep it lean.
That is how I did it and it worked exactly as you asked for inside a RelativeLayout:
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/relativelayout"

android:layout_height="fill_parent" >
<ImageView
android:id="@+id/myImageView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/myImageSouce" />
<TextView
android:id="@+id/myImageViewText"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignLeft="@id/myImageView"
android:layout_alignTop="@id/myImageView"
android:layout_alignRight="@id/myImageView"
android:layout_alignBottom="@id/myImageView"
android:layout_margin="1dp"
android:gravity="center"
android:text="Hello"
android:textColor="#000000" />
</RelativeLayout>
Your regex should work 'as-is'. Assuming that it is doing what you want it to.
wordA(\s*)wordB(?! wordc)
This means match wordA
followed by 0 or more spaces followed by wordB
, but do not match if followed by wordc
. Note the single space between ?!
and wordc
which means that wordA wordB wordc
will not match, but wordA wordB wordc
will.
Here are some example matches and the associated replacement output:
Note that all matches are replaced no matter how many spaces. There are a couple of other points: -
(?! wordc)
is a negative lookahead, so you wont match lines wordA wordB wordc
which is assume is intended (and is why the last line is not matched). Currently you are relying on the space after ?!
to match the whitespace. You may want to be more precise and use (?!\swordc)
. If you want to match against more than one space before wordc you can use (?!\s*wordc)
for 0 or more spaces or (?!\s*+wordc)
for 1 or more spaces depending on what your intention is.
Of course, if you do want to match lines with wordc after wordB then you shouldn't use a negative lookahead.
*
will match 0 or more spaces so it will match wordAwordB. You may want to consider +
if you want at least one space.
(\s*)
- the brackets indicate a capturing group. Are you capturing the whitespace to a group for a reason? If not you could just remove the brackets, i.e. just use \s
.
Update based on comment
Hello the problem is not the expression but the HTML out put that are not considered as whitespace. it's a Joomla website.
Preserving your original regex you can use:
wordA((?:\s| )*)wordB(?!(?:\s| )wordc)
The only difference is that not the regex matches whitespace OR
. I replaced wordc
with \swordc
since that is more explicit. Note as I have already pointed out that the negative lookahead ?!
will not match when wordB is followed by a single whitespace and wordc. If you want to match multiple whitespaces then see my comments above. I also preserved the capture group around the whitespace, if you don't want this then remove the brackets as already described above.
Example matches:
Nuget's Automatic Package Restore is a feature of the Visual Studio (starting in 2013), not MSBuild. You'll have to run nuget.exe restore
if you want to restore packages from the command line.
You can also use the Enable Nuget Package Restore feature, but this is no longer recommended by the nuget folks because it makes intrusive changes to the project files and may cause problems if you build those projects in another solution.
Have you tried this:
function doSomething() {
if ($(this).hasClass('clickedTag')){
// code here
} else {
// and here
}
}
$('.tag1, .tag2').click(doSomething);
Range("A10") = WorksheetFunction.Sum(Worksheets("Sheet1").Range("A1", "A9"))
Where
Range("A10")
is the answer cell
Range("A1", "A9")
is the range to calculate
Namespaces are actually rather passive in the design of the runtime and serve primarily as organizational tools. The Full Name of a type in .NET consists of the Namespace and Class/Enum/Etc. combined. If you only wish to go through a specific assembly, you would simply loop through the types returned by assembly.GetExportedTypes() checking the value of type.Namespace. If you were trying to go through all assemblies loaded in the current AppDomain it would involve using AppDomain.CurrentDomain.GetAssemblies()
Use usort()
and a custom comparison function:
function date_compare($a, $b)
{
$t1 = strtotime($a['datetime']);
$t2 = strtotime($b['datetime']);
return $t1 - $t2;
}
usort($array, 'date_compare');
EDIT: Your data is organized in an array of arrays. To better distinguish those, let's call the inner arrays (data) records, so that your data really is an array of records.
usort
will pass two of these records to the given comparison function date_compare()
at a a time. date_compare
then extracts the "datetime"
field of each record as a UNIX timestamp (an integer), and returns the difference, so that the result will be 0
if both dates are equal, a positive number if the first one ($a
) is larger or a negative value if the second argument ($b
) is larger. usort()
uses this information to sort the array.

The answer to your question "What is the difference between an element and a node" is:
An element is a type of node. Many other types of nodes exist and serve different purposes.

This is the way to include an external javascript file to you HTML markup.
<script type="text/javascript" src="/js/external-javascript.js"></script>
Where external-javascript.js
is the external file to be included. Make sure the path and the file name are correct while you including it.
<a href="javascript:showCountry('countryCode')">countryCode</a>
The above mentioned method is correct for anchor tags and will work perfectly. But for other elements you should specify the event explicitly.
Example:
<select name="users" onChange="showUser(this.value)">

Replace 3000 with whichever port you want. Run below command to kill that process.
sudo kill -9 PID
PID is process ID you want to kill.

$_SERVER['REQUEST_METHOD']
contains the request method (surprise).
$_POST
contains any post data.
It's possible for a POST request to contain no POST data.
I check the request method — I actually never thought about testing the $_POST
array. I check the required post fields, though. So an empty post request would give the user a lot of error messages - which makes sense to me.
It sounds indeed like video streaming more than image streaming, as someone suggested. JPEG/PNG compression isn't targeted for these types of speeds, so forget them.
Imagine having a recording codec on your system that can realtime record an incoming video stream (your screen). A bit like Fraps perhaps. Then imagine a video playback codec on the other side (the remote client). As HD recorders can do it (record live and even playback live from the same HD), so should you, in the end. The HD surely can't deliver images quicker than you can read your display, so that isn't the bottleneck. The bottleneck are the video codecs. You'll find the encoder much more of a problem than the decoder, as all decoders are mostly free.
I'm not saying it's simple; I myself have used DirectShow to encode a video file, and it's not realtime by far. But given the right codec I'm convinced it can work.

Pandas uses numpy

My list is based on three quick searches. One for a list of words not to be capitalized, and one for a full list of prepositions.
One final search made the suggestion that prepositions 5 letters or longer should be capitalized, which is something I liked. My purpose is for informal use. I left 'without' in their, because it's the obvious counterpart to with.
So it capitalizes acronyms, the first letter of the title, and the first letter of most words.
It is not intended to handle words in caps-lock. I wanted to leave those alone.

The necessary method is Mockito#verify:
public static <T> T verify(T mock,
VerificationMode mode)
mock
is your mocked object and mode
is the VerificationMode
that describes how the mock should be verified. Possible modes are:
verify(mock, times(5)).someMethod("was called five times");
verify(mock, never()).someMethod("was never called");
verify(mock, atLeastOnce()).someMethod("was called at least once");
verify(mock, atLeast(2)).someMethod("was called at least twice");
verify(mock, atMost(3)).someMethod("was called at most 3 times");
verify(mock, atLeast(0)).someMethod("was called any number of times"); // useful with captors
verify(mock, only()).someMethod("no other method has been called on the mock");
You'll need these static imports from the Mockito
class in order to use the verify
method and these verification modes:
import static org.mockito.Mockito.atLeast;
import static org.mockito.Mockito.atLeastOnce;
import static org.mockito.Mockito.atMost;
import static org.mockito.Mockito.never;
import static org.mockito.Mockito.only;
import static org.mockito.Mockito.times;
import static org.mockito.Mockito.verify;
So in your case the correct syntax will be:
Mockito.verify(mock, times(4)).send()
This verifies that the method send
was called 4 times on the mocked object. It will fail if it was called less or more than 4 times.
If you just want to check, if the method has been called once, then you don't need to pass a VerificationMode
. A simple
verify(mock).someMethod("was called once");
would be enough. It internally uses verify(mock, times(1)).someMethod("was called once");
.
It is possible to have multiple verification calls on the same mock to achieve a "between" verification. Mockito doesn't support something like this verify(mock, between(4,6)).someMethod("was called between 4 and 6 times");
, but we can write
verify(mock, atLeast(4)).someMethod("was called at least four times ...");
verify(mock, atMost(6)).someMethod("... and not more than six times");
instead, to get the same behaviour. The bounds are included, so the test case is green when the method was called 4, 5 or 6 times.
How do you run a program all by itself without an operating system running?
You place your binary code to a place where processor looks for after rebooting (e.g. address 0 on ARM).
Can you create assembly programs that the computer can load and run at startup ( e.g. boot the computer from a flash drive and it runs the program that is on the drive)?
General answer to the question: it can be done. It's often referred to as "bare metal programming". To read from flash drive, you want to know what's USB, and you want to have some driver to work with this USB. The program on this drive would also have to be in some particular format, on some particular filesystem... This is something that boot loaders usually do, but your program could include its own bootloader so it's self-contained, if the firmware will only load a small block of code.
Many ARM boards let you do some of those things. Some have boot loaders to help you with basic setup.
Here you may find a great tutorial on how to do a basic operating system on a Raspberry Pi.
Edit: This article, and the whole wiki.osdev.org will anwer most of your questions http://wiki.osdev.org/Introduction
Also, if you don't want to experiment directly on hardware, you can run it as a virtual machine using hypervisors like qemu. See how to run "hello world" directly on virtualized ARM hardware here.
Or you can just run power-shell command to append extra folder to the existing path:
$env:Path += ";C:\temp\terraform"
Because os.path.abspath = os.path.dirname + os.path.basename
does not hold. we rather have
os.path.dirname(filename) + os.path.basename(filename) == filename
Both dirname()
and basename()
only split the passed filename into components without taking into account the current directory. If you want to also consider the current directory, you have to do so explicitly.
To get the dirname of the absolute path, use
os.path.dirname(os.path.abspath(__file__))
You probably want egrep. Try:
egrep '^[d-]rwx.*[0-9]$' usrLog.txt
You can simply delete the /var/mail/username
file to delete all emails for a specific user. Also, emails that are outgoing but have not yet been sent will be stored in /var/spool/mqueue
.
You can try something like this:
import java.util.regex.Matcher;
import java.util.regex.Pattern;
public class Main {
public static void main(String[] args) {
System.out.println(from3rd("/folder1/folder2/folder3/"));
}
private static Pattern p = Pattern.compile("(/[^/]*){2}/([^/]*)");
public static String from3rd(String in) {
Matcher m = p.matcher(in);
if (m.matches())
return m.group(2);
else
return null;
}
}
Note that I did some assumptions in the regex:
As requested in a comment, I'll try to explain the regex: (/[^/]*){2}/([^/]*)
/[^/]*
is a /
followed by [^/]*
(any number of characters that are not a /
),(/[^/]*)
groups the previous expression in a single entity. This is the 1
st group of the expression,(/[^/]*){2}
means that the group must match extactly {2}
times,[^/]*
is again any number of characters that are not a /
,([^/]*)
groups the previos expression in a single entity. This is the 2
nd group of the expression.This way you have only to get the substring that matches the 2nd group: return m.group(2);

I had such problem. In my case problem was in data - my column 'information' contained 1 unique value and it caused error
UPDATE: to correct work 'pivot' pairs (id_user,information) cannot have duplicates
It works:

'value': [1, '01.01.00', '01.02.00', 2, '01.03.00', 3, '01.04.00']})
df2.pivot(index='id_user', columns='information', values='value')
it doesn't work:
df2 = pd.DataFrame({'id_user':[1,2,3,4,4,5,5],

You could do this pretty easily with my date-shortcode package:

if you get to use the q library https://github.com/kriskowal/q it has q.allSettled() method that can solve this problem you can handle every promise depending on its state either fullfiled or rejected so
existingPromiseChain = existingPromiseChain.then(function() {
var arrayOfPromises = state.routes.map(function(route){
return route.handler.promiseHandler();
});
return q.allSettled(arrayOfPromises)
});
existingPromiseChain = existingPromiseChain.then(function(arrayResolved) {
//so here you have all your promises the fulfilled and the rejected ones
// you can check the state of each promise
arrayResolved.forEach(function(item){
if(item.state === 'fulfilled'){ // 'rejected' for rejected promises
//do somthing
} else {
// do something else
}
})
// do stuff with my array of resolved promises, eventually ending with a res.send();
});
What about -mmin

Also, make sure to test this first!
... -exec echo rm -f '{}' \; ^^^^ Add the 'echo' so you just see the commands that are going to get run instead of actual trying them first.
Apply this trick.
First you need IP address of url you want to redirect to. Lets say you want to redirect to stackoverflow.com To find it, use the ping command in a Command Prompt. Type in:
ping stackoverflow.com
into the command prompt window and you’ll see stackoverflow's numerical IP address. Now use that IP into your host file

In Bootstrap 3 they do not have separate classes for different styles of labels.
http://getbootstrap.com/components/
However, you can customize bootstrap classes that way. In your css file
.lb-sm {
font-size: 12px;
}
.lb-md {
font-size: 16px;
}
.lb-lg {
font-size: 20px;
}
Alternatively, you can use header tags to change the sizes. For example, here is a medium sized label and a small-sized label
<link href="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css" rel="stylesheet"/>_x000D_
<h3>Example heading <span class="label label-default">New</span></h3>_x000D_
<h6>Example heading <span class="label label-default">New</span></h6>
_x000D_
They might add size classes for labels in future Bootstrap versions.

postgresql get seconds difference between timestamps
SELECT (
(extract (epoch from (
'2012-01-01 18:25:00'::timestamp - '2012-01-01 18:25:02'::timestamp
)
)
)
)::integer
which prints:
-2
Because the timestamps are two seconds apart. Take the number and divide by 60 to get minutes, divide by 60 again to get hours.
For me, WriteXLS
provides the functionality you are looking for. Since you did not specify which errors it returns, I show you an example:
Example
library(WriteXLS)
x <- list(sheet_a = data.frame(a=letters), sheet_b = data.frame(b = LETTERS))
WriteXLS(x, "test.xlsx", names(x))
Explanation
If x
is:
More on usage
?WriteXLS
shows:
`x`: A character vector or factor containing the names of one or
more R data frames; A character vector or factor containing
the name of a single list which contains one or more R data
frames; a single list object of one or more data frames; a
single data frame object.
Solution
For your example, you would need to collect all data.frames in a list during the loop, and use WriteXLS
after the loop has finished.
Session info
The Spring Framework has a class which allows to recursively search through the classpath:
PathMatchingResourcePatternResolver resolver = new PathMatchingResourcePatternResolver();
resolver.getResources("classpath*:some/package/name/**/*.xml");
A way to do this would be to set the color of the element to black, and then fade to the color of the background like this:
<style>
p {
animation-name: example;
animation-duration: 2s;
}
@keyframes example {
from {color:black;}
to {color:white;}
}
</style>
<p>I am FADING!</p>
I hope this is what you needed!
The screenshot you linked to says that WebKit is using the selector input:-webkit-autofill
for those elements. Have you tried putting this in your CSS?
input:-webkit-autofill {
background-color: white !important;
}
If that doesn't work, then nothing probably will. Those fields are highlighted to alert the user that they have been autofilled with private information (such as the user's home address) and it could be argued that allowing a page to hide that is allowing a security risk.
The hint is, the output file is created even if you get this error. The automatic deconstruction of vector starts after your code executed. Elements in the vector are deconstructed as well. This is most probably where the error occurs. The way you access the vector is through vector::operator[]
with an index read from stream. Try vector::at()
instead of vector::operator[]
. This won't solve your problem, but will show which assignment to the vector causes error.
try this formula in column E:
=IF( AND( ISNUMBER(D2), D2=G2), H2, "")
your error is the number test, ISNUMBER( ISMATCH(D2,G:G,0) )
you do check if ismatch is-a-number, (i.e. isNumber("true") or isNumber("false"), which is not!.
I hope you understand my explanation.

The ggplot2
package takes a little bit of learning, but the results look really nice, you get nice legends, plus many other nice features, all without having to write much code.
require(ggplot2)
require(reshape2)
df <- data.frame(time = 1:10,
a = cumsum(rnorm(10)),
b = cumsum(rnorm(10)),
c = cumsum(rnorm(10)))
df <- melt(df , id.vars = 'time', variable.name = 'series')
# plot on same grid, each series colored differently --
# good if the series have same scale
ggplot(df, aes(time,value)) + geom_line(aes(colour = series))
# or plot on different plots
ggplot(df, aes(time,value)) + geom_line() + facet_grid(series ~ .)
To be precise,
Thread.isAlive()
returns true if the thread has been started (may not yet be running) but has not yet completed its run method.
Thread.getState()
returns the exact state of the thread.
You can associate the same value with many keys, or just remove a key and re-add a new key with the same value.
For example, if you have keys->values:
red->1
blue->2
green->4
there's no reason you can't add purple->2
or remove red->1
and add orange->1
Several of the questions/comments I've seen around this subject sound to me as if the person is using Namespace
where they mean 'module alias'. As Ryan Cavanaugh mentioned in one of his comments you can have a 'Wrapper' module re-export several modules.
If you really want to import it all from the same module name/alias, combine a wrapper module with a paths mapping in your tsconfig.json
.
Example:
./path/to/CompanyName.Products/Foo.ts
export class Foo {
...
}
./path/to/CompanyName.Products/Bar.ts
export class Bar {
...
}
./path/to/CompanyName.Products/index.ts
export { Foo } from './Foo';
export { Bar } from './Bar';
tsconfig.json
{
"compilerOptions": {
...
paths: {
...
"CompanyName.Products": ["./path/to/CompanyName.Products/index"],
...
}
...
}
...
}
main.ts
import { Foo, Bar } from 'CompanyName.Products'
Note: The module resolution in the output .js files will need to be handled somehow, such as with this https://github.com/tleunen/babel-plugin-module-resolver
Example .babelrc
to handle the alias resolution:
{
"plugins": [
[ "module-resolver", {
"cwd": "babelrc",
"alias": {
"CompanyName.Products": "./path/to/typescript/build/output/CompanyName.Products/index.js"
}
}],
... other plugins ...
]
}
This will ensure all WEB-INF/lib jars are included on the classpath.
I think the best way to accomplish what you're talking about is to have a set of divs that will be your columns, and populate those in the way you described. Then fill those divs vertically with the content you're talking about.
On the Linux system you can do following (Should be similar for other OS)
Check if mysql process is running:
sudo service mysql status
If runnning then stop the process: (Make sure you close all mysql tool)
sudo service mysql stop
If you have issue stopping then do following
Search for process: ps aux | grep mysqld
Kill the process: kill -9 process_id
Now start mysql in safe mode with skip grant
sudo mysqld_safe --skip-grant-tables &

There is a lot of confusion on this topic because there are so many different ways to do it.
Here are the appropriate types used in the following screen shots:
private route: ActivatedRoute
private router: Router
1) Required Routing Parameters:
2) Route Optional Parameters:
3) Route Query Parameters:
4) You can use a service to pass data from one component to another without using route parameters at all.

can i just throw in that if you distort your images too much, ie take them out of a ratio, they may not look right, - a tiny amount is fine, but one way to do this is put the images inside a 'container' and set the container to the 100 x 100, then set your image to overflow none, and set the smallest width to the maximum width of the container, this will crop a bit of your image though,
for example
<h4>Products</h4>
<ul class="products">
<li class="crop">
<img src="ipod.jpg" alt="iPod" />
</li>
</ul>
.crop {
height: 300px;
width: 400px;
overflow: hidden;
}
.crop img {
height: auto;
width: 400px;
}
This way the image will stay the size of its container, but will resize without breaking constraints
if you want to custom the error type, a simple thing you can do is to define an error class based on ValueError.
Change ng-disabled="!contractTypeValid"
to [disabled]="!contractTypeValid"
Try to do it with focusout
$("textarea").focusout(function() {
alert('textarea focusout');
});
You can use jQuery's $.map
.
var foo = { 'alpha' : 'puffin', 'beta' : 'beagle' },
keys = $.map(foo, function(v, i){
return i;
});
Just go to the SQL Server Management Studio -> Tools -> Options -> Designer; and Uncheck the option "prevent saving changes that require table re-creation".

Browser have cross domain security at client side which verify that server allowed to fetch data from your domain. If Access-Control-Allow-Origin
not available in response header, browser disallow to use response in your JavaScript code and throw exception at network level. You need to configure cors
at your server side.
You can fetch request using mode: 'cors'
. In this situation browser will not throw execption for cross domain, but browser will not give response in your javascript function.
So in both condition you need to configure cors
in your server or you need to use custom proxy server.
I've used encodeURIComponent() and decodeURIComponent() too.
Yes. See Named and Optional Arguments. Note that the default value needs to be a constant, so this is OK:
public string Foo(string myParam = "default value") // constant, OK
{
}
but this is not:
public void Bar(string myParam = Foo()) // not a constant, not OK
{
}
You can call run-time commands from java for both Windows and Linux.
import java.io.*;
public class Test{
public static void main(String[] args)
{
try
{
Process process = Runtime.getRuntime().exec("pwd"); // for Linux
//Process process = Runtime.getRuntime().exec("cmd /c dir"); //for Windows
process.waitFor();
BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream()));
String line;
while ((line=reader.readLine())!=null)
{
System.out.println(line);

}
catch(Exception e)
{
System.out.println(e);
}
finally
{
process.destroy();
}

I know this is old and that this is a little off topic, but supposing you wanted to uncheck only specific radio buttons in a collection:
$("#go").click(function(){_x000D_
$("input[name='correctAnswer']").each(function(){_x000D_
if($(this).val() !== "1"){_x000D_
$(this).prop("checked",false);_x000D_
}_x000D_
});_x000D_
});
_x000D_
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>_x000D_
<input id="radio1" type="radio" name="correctAnswer" value="1">1</input>_x000D_
<input id="radio2" type="radio" name="correctAnswer" value="2">2</input>_x000D_
<input id="radio3" type="radio" name="correctAnswer" value="3">3</input>_x000D_
<input id="radio4" type="radio" name="correctAnswer" value="4">4</input>_x000D_
<input type="button" id="go" value="go">
_x000D_
And if you are dealing with a radiobutton list, you can use the :checked selector to get just the one you want.
$("#go").click(function(){
$("input[name='correctAnswer']:checked").prop("checked",false);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>

<input id="radio2" type="radio" name="correctAnswer" value="2">2</input>
<input id="radio3" type="radio" name="correctAnswer" value="3">3</input>

The mail server on CentOS 6 and other IPv6 capable server platforms may be bound to IPv6 localhost (::1) instead of IPv4 localhost (127.0.0.1).
Typical symptoms:
[root@host /]# telnet 127.0.0.1 25
Trying 127.0.0.1...
telnet: connect to address 127.0.0.1: Connection refused
[root@host /]# telnet localhost 25
Trying ::1...
Connected to localhost.
Escape character is '^]'.
220 host ESMTP Exim 4.72 Wed, 14 Aug 2013 17:02:52 +0100
[root@host /]# netstat -plant | grep 25
tcp 0 0 :::25 :::* LISTEN 1082/exim
If this happens, make sure that you don't have two entries for localhost
in /etc/hosts
with different IP addresses, like this (bad) example:
[root@host /]# cat /etc/hosts
127.0.0.1 localhost.localdomain localhost localhost4.localdomain4 localhost4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
To avoid confusion, make sure you only have one entry for localhost
, preferably an IPv4 address, like this:
[root@host /]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4.localdomain4 localhost4
::1 localhost6 localhost6.localdomain6
This problem:
$ brew install docker docker-machine
$ docker ps
Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?
This apparently meant do the following:
$ docker-machine create default # default driver is apparently vbox:
Running pre-create checks...
Error with pre-create check: "VBoxManage not found. Make sure VirtualBox is installed and VBoxManage is in the path"
$ brew cask install virtualbox
…
$ docker-machine create default
# works this time
$ docker ps
Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?
$ eval "$(docker-machine env default)"
$ docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
It finally works.
You can use the “xhyve” driver if you don’t want to install virtual box.
Also you can install the “docker app” (then run it) which apparently makes it so you don’t have to run some of the above. brew cask install docker
then run the app, see the other answers. But apparently isn't necessary per se.
This error occurs when the client URL and server URL don't match, including the port number. In this case you need to enable your service for CORS which is cross origin resource sharing.
If you are hosting a Spring REST service then you can find it in the blog post CORS support in Spring Framework.
If you are hosting a service using a Node.js server then
npm install cors --save
Add following lines to your server.js
var cors = require('cors')
app.use(cors()) // Use this after the variable declaration
The easiest way would be to use:
SELECT DATE(GETDATE())
SELECT
a.nameA, /* TableA.nameA */
d.nameD /* TableD.nameD */
FROM TableA a
INNER JOIN TableB b on b.aID = a.aID
INNER JOIN TableC c on c.cID = b.cID
INNER JOIN TableD d on d.dID = a.dID
WHERE DATE(c.`date`) = CURDATE()
To refresh the whole page, but it works normally:
Response.Redirect(url,bool)
Herb Sutter has an excellent article on string formatting. I recommend reading it. I've linked it before on SO.
What is the datatype for column1 in your Hive table? Please note that if your column is STRING it won't be having a NULL value even though your external file does not have any data for that column.
TL;DR
Use Promise.all
for the parallel function calls, the answer behaviors not correctly when the error occurs.
First, execute all the asynchronous calls at once and obtain all the Promise
objects. Second, use await
on the Promise
objects. This way, while you wait for the first Promise
to resolve the other asynchronous calls are still progressing. Overall, you will only wait for as long as the slowest asynchronous call. For example:
// Begin first call and store promise without waiting
const someResult = someCall();
// Begin second call and store promise without waiting
const anotherResult = anotherCall();
// Now we await for both results, whose async processes have already been started
const finalResult = [await someResult, await anotherResult];
// At this point all calls have been resolved
// Now when accessing someResult| anotherResult,
// you will have a value instead of a promise
JSbin example: http://jsbin.com/xerifanima/edit?js,console
Caveat: It doesn't matter if the await
calls are on the same line or on different lines, so long as the first await
call happens after all of the asynchronous calls. See JohnnyHK's comment.
Update: this answer has a different timing in error handling according to the @bergi's answer, it does NOT throw out the error as the error occurs but after all the promises are executed.

Unobtrusive JavaScript approach was good in the PAST - especially events handler bind in HTML was considered as bad practice (mainly because onclick events run in the global scope and may cause unexpected error
what was mention by YiddishNinja)
Currently it seems that this approach is a little outdated and needs some update. If someone want to be professional frontend developper and write large and complicated apps then he need to use frameworks like Angular, Vue.js, etc... However that frameworks usually use (or allow to use) HTML-templates where event handlers are bind in html-template code directly and this is very handy, clear and effective - e.g. in angular template usually people write:
<button (click)="someAction()">Click Me</button>
In raw js/html the equivalent of this will be
<button onclick="someAction()">Click Me</button>
The difference is that in raw js onclick
event is run in the global scope - but the frameworks provide encapsulation.
The problem is when novice programmer who always heard that html-onclick is bad and who always use btn.addEventListener("onclick", ... )
wants to use some framework with templates (addEventListener
also have drawbacks - if we update DOM in dynamic way using innerHTML=
(which is pretty fast) - then we loose events handlers bind in that way). Then he will face something like bad-habits or wrong-approach to framework usage - and he will use framework in very bad way - because he will focus mainly on js-part and no on template-part (and produce unclear and hard to maintain code). To change this habits he will loose a lot of time (and probably he will need some luck and teacher).
So in my opinion, based on experience with my students, better would be for them if they use html-handlers-bind at the beginning. As I say it is true that handlers are call in global scope but a this stage students usually create small applications which are easy to control. To write bigger applications they choose some frameworks.
We can UPDATE the Unobtrusive JavaScript approach and allow bind event handlers (eventually with simple parameters) in html (but only bind handler - not put logic into onclick like in OP quesiton). So in my opinion in raw js/html this should be allowed
<button onclick="someAction(3)">Click Me</button>
or
function popup(num,str,event) {_x000D_
let re=new RegExp(str); _x000D_
// ... _x000D_
event.preventDefault();_x000D_
console.log("link was clicked");_x000D_
}
_x000D_
<a href="https://example.com" onclick="popup(300,'map',event)">link</a>
_x000D_
But below examples should NOT be allowed
<button onclick="console.log('xx'); someAction(); return true">Click Me</button>
<a href="#" onclick="popup('/map/', 300, 300, 'map'); return false;">link</a>
The reality changes, our point of view should too
For anyone else who lands here I'd like to add on to Günter Zöchbauer's answer this was my solution for implementing a utility to know if there's internet or not regardless of anything else.
Disclaimer:
I'm new to both Dart and Flutter so this may not be the best approach, but would love to get feedback.
My requirements
I didn't want to have a bunch of repeated code anywhere I needed to check the connection and I wanted it to automatically update components or anything else that cared about the connection whenever there was a change.
First we setup a Singleton. If you're unfamiliar with this pattern there's a lot of good info online about them. But the gist is that you want to make a single instance of a class during the application life cycle and be able to use it anywhere.
This singleton hooks into flutter_connectivity
and listens for connectivity changes, then tests the network connection, then uses a StreamController
to update anything that cares.
It looks like this:
import 'dart:io'; //InternetAddress utility
import 'dart:async'; //For StreamController/Stream
import 'package:connectivity/connectivity.dart';
class ConnectionStatusSingleton {
//This creates the single instance by calling the `_internal` constructor specified below
static final ConnectionStatusSingleton _singleton = new ConnectionStatusSingleton._internal();
ConnectionStatusSingleton._internal();
//This is what's used to retrieve the instance through the app
static ConnectionStatusSingleton getInstance() => _singleton;
//This tracks the current connection status
bool hasConnection = false;
//This is how we'll allow subscribing to connection changes
StreamController connectionChangeController = new StreamController.broadcast();
//flutter_connectivity
final Connectivity _connectivity = Connectivity();
//Hook into flutter_connectivity's Stream to listen for changes
//And check the connection status out of the gate
void initialize() {
_connectivity.onConnectivityChanged.listen(_connectionChange);
checkConnection();
}
Stream get connectionChange => connectionChangeController.stream;
//A clean up method to close our StreamController
// Because this is meant to exist through the entire application life cycle this isn't
// really an issue
void dispose() {
connectionChangeController.close();
}
//flutter_connectivity's listener
void _connectionChange(ConnectivityResult result) {
checkConnection();
}
//The test to actually see if there is a connection
Future<bool> checkConnection() async {
bool previousConnection = hasConnection;
try {
final result = await InternetAddress.lookup('google.com');
if (result.isNotEmpty && result[0].rawAddress.isNotEmpty) {
hasConnection = true;
} else {
hasConnection = false;
}
} on SocketException catch(_) {
hasConnection = false;
}
//The connection status changed send out an update to all listeners
if (previousConnection != hasConnection) {
connectionChangeController.add(hasConnection);
}
return hasConnection;
}
}
Initialization
First we have to make sure we call the initialize of our singleton. But only once.
This parts up to you but I did it in my app's main()
:
void main() {
ConnectionStatusSingleton connectionStatus = ConnectionStatusSingleton.getInstance();
connectionStatus.initialize();
runApp(MyApp());
//Call this if initialization is occuring in a scope that will end during app lifecycle
//connectionStatus.dispose();
}
In Widget
or elsewhere
import 'dart:async'; //For StreamSubscription
...
class MyWidgetState extends State<MyWidget> {
StreamSubscription _connectionChangeStream;
bool isOffline = false;
@override
initState() {
super.initState();
ConnectionStatusSingleton connectionStatus = ConnectionStatusSingleton.getInstance();
_connectionChangeStream = connectionStatus.connectionChange.listen(connectionChanged);
}
void connectionChanged(dynamic hasConnection) {
setState(() {
isOffline = !hasConnection;
});
}
@override
Widget build(BuildContext ctxt) {
...
}
}
Hope somebody else finds this useful!

If you are looking to reduce the size using coding itself, you can follow this code in php.
<?php
function compress($source, $destination, $quality) {
$info = getimagesize($source);
if ($info['mime'] == 'image/jpeg')
$image = imagecreatefromjpeg($source);
elseif ($info['mime'] == 'image/gif')
$image = imagecreatefromgif($source);
elseif ($info['mime'] == 'image/png')
$image = imagecreatefrompng($source);
imagejpeg($image, $destination, $quality);
return $destination;
}
$source_img = 'source.jpg';
$destination_img = 'destination .jpg';
$d = compress($source_img, $destination_img, 90);
?>
$d = compress($source_img, $destination_img, 90);
This is just a php function that passes the source image ( i.e., $source_img
), destination image ( $destination_img
) and quality for the image that will take to compress ( i.e., 90 ).
$info = getimagesize($source);
The getimagesize()
function is used to find the size of any given image file and return the dimensions along with the file type.
When I started learning Spring Security, then I overrided the method userDetailsService() as in below code snippet:
@Configuration
@EnableWebSecurity
public class ApplicationSecurityConfiguration extends WebSecurityConfigurerAdapter{
@Override
protected void configure(HttpSecurity http) throws Exception {
http
.csrf().disable()
.authorizeRequests()
.antMatchers("/", "/index").permitAll()
.anyRequest().authenticated()
.and()
.httpBasic();
}
@Override
@Bean
public UserDetailsService userDetailsService() {
List<UserDetails> users= new ArrayList<UserDetails>();
users.add(User.withDefaultPasswordEncoder().username("admin").password("nimda").roles("USER","ADMIN").build());
users.add(User.withDefaultPasswordEncoder().username("Spring").password("Security").roles("USER").build());
return new InMemoryUserDetailsManager(users);
}
}
So we can log in to the application using the above-mentioned creds. (e.g. admin/nimda)
Note: This we should not use in production.
I do both web (node) and Android development, and open Android Studio device simulator and docker together, both of them use port 8601, it complained socket hang up
error, after close Android Studio device simulator and it works well in node side. Don’t use Android Studio device simulator and docker together.
The only thing that might make a checksum comparison slightly faster than a byte-by-byte comparison is the fact that you are reading one file at a time, somewhat reducing the seek time for the disk head. That slight gain may however very well be eaten up by the added time of calculating the hash.
Also, a checksum comparison of course only has any chance of being faster if the files are identical. If they are not, a byte-by-byte comparison would end at the first difference, making it a lot faster.
You should also consider that a hash code comparison only tells you that it's very likely that the files are identical. To be 100% certain you need to do a byte-by-byte comparison.
If the hash code for example is 32 bits, you are about 99.99999998% certain that the files are identical if the hash codes match. That is close to 100%, but if you truly need 100% certainty, that's not it.
It's not a bug in ARel, it's a bug in your logic.
What you want here is:
Foo.includes(:bar).where(Bar.arel_table[:id].not_eq(nil))
If I understand correctly, you want PowerShell to send the ENTER keystroke to some interactive application?
$wshell = New-Object -ComObject wscript.shell;
$wshell.AppActivate('title of the application window')
Sleep 1
$wshell.SendKeys('~')
If that interactive application is a PowerShell script, just use whatever is in the title bar of the PowerShell window as the argument to AppActivate (by default, the path to powershell.exe). To avoid ambiguity, you can have your script retitle its own window by using the title 'new window title'
command.
A few notes:
{ENTER}
, though they're not identical - that's the keypad's ENTER key. A complete list is available here: http://msdn.microsoft.com/en-us/library/office/aa202943%28v=office.10%29.aspx.Sleep 1
statement is to wait 1 second because it takes a moment for the window to activate, and if you invoke SendKeys immediately, it'll send the keys to the PowerShell window, or to nowhere.Sometimes wscript.shell's SendKeys method can be a little quirky, so if you run into problems, replace the fourth line above with this:
Add-Type -AssemblyName System.Windows.Forms
[System.Windows.Forms.SendKeys]::SendWait('~');
public int this[int key]
{
get => GetValue(key);
set => SetValue(key, value);
}
You can use initial which is explained here
You have two options either populate the value when calling form constructor:
form = JournalForm(initial={'tank': 123})
or set the value in the form definition:
tank = forms.IntegerField(widget=forms.HiddenInput(), initial=123)
$("#regTitle")[0].innerHTML = 'Hello World';
Simplay you can place HTML select attribute to option
a
like shown below
Define the attributes like selected="selected"
<select>
<option selected="selected">a</option>
<option>b</option>
<option>c</option>
</select>
Even though this question was long time ago, thanks all for the inputs that helping me out a similar problem. I also made a bit modification based on the others' answers here and making multiple inputs/valuables into a Single Object (json); and hope this helps someone.
js:
//example: params={id:'123',name:'foo'};
mapInput.name = "data";
mapInput.value = JSON.stringify(params);
php:
$data=json_decode($_POST['data']);
echo $data->id;
echo $data->name;
Wrap all the children inside of another LinearLayout with wrap_content
for both the width and the height as well as the vertical orientation.
This worked for me :
select option {
color: black;
}
select:not(:checked) {
color: gray;
}
For anyone still having the problem. You could use official Microsoft SMO
using (var connection = new SqlConnection(connectionString))
{
var server = new Server(new ServerConnection(connection));
server.ConnectionContext.ExecuteNonQuery(sql);
}
Try this code. Add this snippet to your res>values>styles.xml
<style name="AppTheme" parent="AppBaseTheme">
<item name="android:actionBarWidgetTheme">@style/Theme.stylingactionbar.widget</item>
</style>
<style name="PopupMenu" parent="@android:style/Widget.Holo.ListPopupWindow">
<item name="android:popupBackground">@color/DarkSlateBlue</item>
<!-- for @color you have to create a color.xml in res > values -->
</style>
<style name="Theme.stylingactionbar.widget" parent="@android:style/Theme.Holo">
<item name="android:popupMenuStyle">@style/PopupMenu</item>
</style>
And in Manifest.xml add below snippet under application
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
The easy way is to define a non-ASCII character... as a character that is not an ASCII character.
LC_ALL=C grep '[^ -~]' file.xml
Add a tab after the ^
if necessary.
Setting LC_COLLATE=C
avoids nasty surprises about the meaning of character ranges in many locales. Setting LC_CTYPE=C
is necessary to match single-byte characters — otherwise the command would miss invalid byte sequences in the current encoding. Setting LC_ALL=C
avoids locale-dependent effects altogether.

I had the same issue and here is how I manage to pass through:
In your case you have addToCount()
which is called. now to pass down a param when user clicks, you can say @click="addToCount(item.contactID)"
in your function implementation you can receive the params like:
addToCount(paramContactID){
// the paramContactID contains the value you passed into the function when you called it
// you can do what you want to do with the paramContactID in here!
}
You can listen to the dragend
event, and if the map is dragged outside the allowed bounds, move it back inside. You can define your allowed bounds in a LatLngBounds
object and then use the contains()
method to check if the new lat/lng center is within the bounds.
You can also limit the zoom level very easily.

var strictBounds = new google.maps.LatLngBounds(
new google.maps.LatLng(28.70, -127.50),
new google.maps.LatLng(48.85, -55.90)
);
// Listen for the dragend event
google.maps.event.addListener(map, 'dragend', function() {
if (strictBounds.contains(map.getCenter())) return;
// We're out of bounds - Move the map back within the bounds
var c = map.getCenter(),
x = c.lng(),
y = c.lat(),
maxX = strictBounds.getNorthEast().lng(),
maxY = strictBounds.getNorthEast().lat(),
minX = strictBounds.getSouthWest().lng(),
minY = strictBounds.getSouthWest().lat();
if (x < minX) x = minX;
if (x > maxX) x = maxX;
if (y < minY) y = minY;
if (y > maxY) y = maxY;
map.setCenter(new google.maps.LatLng(y, x));
});
// Limit the zoom level
google.maps.event.addListener(map, 'zoom_changed', function() {

The question is contradictory. It asks for a date without a time of day yet displays an example with a time of 00:00:00
.
UPDATE: The Joda-Time project is now in maintenance mode, with the team advising migration to the java.time classes. See my other Answer for java.time solution.
If instead you want the time-of-day set to the first moment of the day, use a DateTime
object on the Joda-Time library and call its withTimeAtStartOfDay
method. Be aware that the first moment may not be the time 00:00:00
because of Daylight Saving Time or perhaps other anomalies.
ul {
padding-left: 0;
list-style-position: inside;
}
Explanation:
The first property padding-left: 0
clears the default padding/spacing for the ul
element while list-style-position: inside
makes the dots/bullets of li
aligned like a normal text.
So this code

Created a base class based on @sky-dev implementation. So this can be easily applied to multiple contexts, and entities.
public abstract class BaseDbContext<TEntity> : DbContext where TEntity : class
{
public BaseDbContext(string connectionString)
: base(connectionString)
{
}
public override int SaveChanges()
{
UpdateDates();
return base.SaveChanges();
}
private void UpdateDates()
{
foreach (var change in ChangeTracker.Entries<TEntity>())
{
var values = change.CurrentValues;
foreach (var name in values.PropertyNames)
{
var value = values[name];
if (value is DateTime)
{
var date = (DateTime)value;
if (date < SqlDateTime.MinValue.Value)
{
values[name] = SqlDateTime.MinValue.Value;
}
else if (date > SqlDateTime.MaxValue.Value)
{
values[name] = SqlDateTime.MaxValue.Value;
}
}
}
}
}
}
Usage:
public class MyContext: BaseDbContext<MyEntities>
{
/// <summary>
/// Initializes a new instance of the <see cref="MyContext"/> class.
/// </summary>
public MyContext()
: base("name=MyConnectionString")
{
}
/// <summary>
/// Initializes a new instance of the <see cref="MyContext"/> class.
/// </summary>
/// <param name="connectionString">The connection string.</param>
public MyContext(string connectionString)
: base(connectionString)
{

The brute force method of generating every single possible board and scoring it based on the boards it later produces further down the tree doesn't require much memory, especially once you recognize that 90 degree board rotations are redundant, as are flips about the vertical, horizontal, and diagonal axis.
Once you get to that point, there's something like less than 1k of data in a tree graph to describe the outcome, and thus the best move for the computer.

Just to help someone who get here... You should not use $parent.$index as it's not really safe. If you add an ng-if inside the loop, you get the $index messed!
Right way
<table>
<tr ng-repeat="row in rows track by $index" ng-init="rowIndex = $index">
<td ng-repeat="column in columns track by $index" ng-init="columnIndex = $index">
<b ng-if="rowIndex == columnIndex">[{{rowIndex}} - {{columnIndex}}]</b>
<small ng-if="rowIndex != columnIndex">[{{rowIndex}} - {{columnIndex}}]</small>
</td>
</tr>
</table>
I would check to see if the SqlDataReader has rows returned first:
SqlDataReader dr = cmd10.ExecuteReader();
if (dr.HasRows)
{

I want to add another solution: In my case, I need to use a Enum group in a drop down button list items. So they might have space, i.e. more user friendly descriptions needed:
public enum CancelReasonsEnum
{
[Description("In rush")]
InRush,
[Description("Need more coffee")]
NeedMoreCoffee,
[Description("Call me back in 5 minutes!")]
In5Minutes
}
In a helper class (HelperMethods) I created the following method:
public static List<string> GetListOfDescription<T>() where T : struct
{
Type t = typeof(T);
return !t.IsEnum ? null : Enum.GetValues(t).Cast<Enum>().Select(x => x.GetDescription()).ToList();
}
When you call this helper you will get the list of item descriptions.
List<string> items = HelperMethods.GetListOfDescription<CancelReasonEnum>();
ADDITION: In any case, if you want to implement this method you need :GetDescription extension for enum. This is what I use.
public static string GetDescription(this Enum value)
{
Type type = value.GetType();
string name = Enum.GetName(type, value);
if (name != null)
{
FieldInfo field = type.GetField(name);
if (field != null)
{
DescriptionAttribute attr =Attribute.GetCustomAttribute(field,typeof(DescriptionAttribute)) as DescriptionAttribute;
if (attr != null)
{
return attr.Description;
}
}
}
return null;
/* how to use
MyEnum x = MyEnum.NeedMoreCoffee;
string description = x.GetDescription();
*/
}
I'm not sure what the problem is; running the below works as expected:
<div id="thumb0" class="thumbs" onclick="klikaj('rad1')">knock knock</div>
?<div id="rad1" style="visibility: hidden">hello world</div>????????????????????????????????
<script>
function klikaj(i) {
document.getElementById(i).style.visibility='visible';
}
</script>

Yes, there is a way to write to the event log you are looking for. You don't need to create a new source, just simply use the existent one, which often has the same name as the EventLog's name and also, in some cases like the event log Application, can be accessible without administrative privileges*.
*Other cases, where you cannot access it directly, are the Security EventLog, for example, which is only accessed by the operating system.
I used this code to write directly to the event log Application:
using (EventLog eventLog = new EventLog("Application"))
{
eventLog.Source = "Application";
eventLog.WriteEntry("Log message example", EventLogEntryType.Information, 101, 1);
}
As you can see, the EventLog source is the same as the EventLog's name. The reason of this can be found in Event Sources @ Windows Dev Center (I bolded the part which refers to source name):
Each log in the Eventlog key contains subkeys called event sources. The event source is the name of the software that logs the event. It is often the name of the application or the name of a subcomponent of the application if the application is large. You can add a maximum of 16,384 event sources to the registry.

As shown on the official page and suggested by David:
Create a style:
.no-close .ui-dialog-titlebar-close {
display: none;
}
Then, you can simply add the no-close class to any dialog in order to hide it's close button:
$( "#dialog" ).dialog({
dialogClass: "no-close",
buttons: [{
text: "OK",
click: function() {
$( this ).dialog( "close" );
}
}]
});

-Copy property values from the origin bean to the destination bean for all cases where the property names are the same.
Here is another ThrowIfNull implementation:
[ThreadStatic]
private static string lastMethodName = null;
[ThreadStatic]
private static int lastParamIndex = 0;
[MethodImpl(MethodImplOptions.NoInlining)]
public static void ThrowIfNull<T>(this T parameter)
{
var currentStackFrame = new StackFrame(1);
var props = currentStackFrame.GetMethod().GetParameters();
if (!String.IsNullOrEmpty(lastMethodName)) {
if (currentStackFrame.GetMethod().Name != lastMethodName) {
lastParamIndex = 0;
} else if (lastParamIndex >= props.Length - 1) {
lastParamIndex = 0;
} else {
lastParamIndex++;
}
} else {
lastParamIndex = 0;
}
if (!typeof(T).IsValueType) {
for (int i = lastParamIndex; i < props.Length; i++) {
if (props[i].ParameterType.IsValueType) {
lastParamIndex++;
} else {
break;
}
}
}
if (parameter == null) {
string paramName = props[lastParamIndex].Name;
throw new ArgumentNullException(paramName);
}
lastMethodName = currentStackFrame.GetMethod().Name;
}
It's not as efficient as the other impementations, but has cleaner usage:
public void Foo()
{
Bar(1, 2, "Hello", "World"); //no exception
Bar(1, 2, "Hello", null); //exception
Bar(1, 2, null, "World"); //exception
}
public void Bar(int x, int y, string someString1, string someString2)
{
//will also work with comments removed
//x.ThrowIfNull();
//y.ThrowIfNull();
someString1.ThrowIfNull();
someString2.ThrowIfNull();
//Do something incredibly useful here!
}
Changing the parameters to int? will also work.

If you still want to group only by one column (as I wanted) you can nest the query:
select c1, count(*) from (select distinct c1, c2 from t) group by c1
(function ($) {
$(document).ready(function(){
$("#myspan").text("This is span");
});
}(jQuery));
_x000D_
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<span id="myspan"> hereismytext </span>
_x000D_
user text()
to change span text.
Update: I still get upvotes on this question, which is still the accepted answer and which I think I answered poorly. In the spirit of making sure the best info is out there, I have decided to update this answer.
In modern Android I would use ConstraintLayout
to do this. It is more performant and straightforward.
<ConstraintLayout>
<View
android:id="@+id/view1"
...other attributes elided... />
<View
android:id="@id/view2"
app:layout_constraintTop_toBottomOf="@id/view1" />
...other attributes elided... />
...etc for other views that should be aligned top to bottom...
<TextView
app:layout_constraintBottom_toBottomOf="parent" />
If you don't want to use a ConstraintLayout, using a LinearLayout with an expanding view is a straightforward and great way to handle taking up the extra space (see the answer by @Matthew Wills). If you don't want to expand the background of any of the Views above the bottom view, you can add an invisible View to take up the space.
The answer I originally gave works but is inefficient. Inefficiency may not be a big deal for a single top level layout, but it would be a terrible implementation in a ListView
or RecyclerView
, and there just isn't any reason to do it since there are better ways to do it that are roughly the same level of effort and complexity if not simpler.
Take the TextView out of the LinearLayout, then put the LinearLayout and the TextView inside a RelativeLayout. Add the attribute android:layout_alignParentBottom="true"
to the TextView. With all the namespace and other attributes except for the above attribute elided:
<RelativeLayout>
<LinearLayout>
<!-- All your other elements in here -->
</LinearLayout>
<TextView
android:layout_alignParentBottom="true" />
</RelativeLayout>
Here is what worked for me:
protected override System.Net.WebRequest GetWebRequest(Uri uri)
{
HttpWebRequest request;
request = (HttpWebRequest)base.GetWebRequest(uri);
NetworkCredential networkCredentials =
Credentials.GetCredential(uri, "Basic");
if (networkCredentials != null)
{
byte[] credentialBuffer = new UTF8Encoding().GetBytes(
networkCredentials.UserName + ":" +
networkCredentials.Password);
request.Headers["Authorization"] =
"Basic " + Convert.ToBase64String(credentialBuffer);
request.Headers["Cookie"] = "BCSI-CS-2rtyueru7546356=1";
request.Headers["Cookie2"] = "$Version=1";
}
else
{
throw new ApplicationException("No network credentials");
}
return request;
}
Don't forget to set this property:
service.Credentials = new NetworkCredential("username", "password");
Cookie and Cookie2 are set in header because java service was not accepting the request and I was getting Unauthorized error.
Take a look at ?legend
and try this:
legend('topright', names(a)[-1] ,
lty=1, col=c('red', 'blue', 'green',' brown'), bty='n', cex=.75)
I was creating a mp3 player app for android, so I did it like this to get current time and duration
private String millisecondsToTime(long milliseconds) {
long minutes = (milliseconds / 1000) / 60;
long seconds = (milliseconds / 1000) % 60;
String secondsStr = Long.toString(seconds);
String secs;
if (secondsStr.length() >= 2) {
secs = secondsStr.substring(0, 2);
} else {
secs = "0" + secondsStr;
}
return minutes + ":" + secs;
}
Using Date pattern yyyy-MM-dd'T'HH:mm:ss.SSS'Z'
and Java 8 you could do
String string = "2018-04-10T04:00:00.000Z";
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'", Locale.ENGLISH);
LocalDate date = LocalDate.parse(string, formatter);
System.out.println(date);
Update: For pre 26 use Joda time
String string = "2018-04-10T04:00:00.000Z";
DateTimeFormatter formatter = DateTimeFormat.forPattern("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'");
LocalDate date = org.joda.time.LocalDate.parse(string, formatter);
In app/build.gradle file, add like this-
dependencies {
compile 'joda-time:joda-time:2.9.4'
}
After much pain, and great assistance from @vitr et al above, i decided to try
and that worked.
ENV LISTEN_PORT=""
ENTRYPOINT java -cp "app:app/lib/*" hello.Application --server.port=${LISTEN_PORT:-80}
e.g.
docker run --rm -p 8080:8080 -d --env LISTEN_PORT=8080 my-image
and
docker run --rm -p 8080:80 -d my-image
both set the port correctly in my container

You can use the following to get the previous URL.
var oldURL = document.referrer;
alert(oldURL);
The limitation of execl is that when executing a shell command or any other script that is not in the current working directory, then we have to pass the full path of the command or the script. Example:
execl("/bin/ls", "ls", "-la", NULL);
The workaround to passing the full path of the executable is to use the function execlp, that searches for the file (1st argument of execlp) in those directories pointed by PATH:
execlp("ls", "ls", "-la", NULL);
Seems like the only way to get decimal in a pretty (for me) form requires some ridiculous code.
The only solution I got so far:
CASE WHEN xy>0 and xy<1 then '0' || to_char(xy) else to_char(xy)
xy
is a decimal.
xy query result
0.8 0.8 --not sth like .80
10 10 --not sth like 10.00
'
origin/master
' which can not be resolved as commit
Strange: you need to check your remotes:
git remote -v
And make sure origin
is fetched:
git fetch origin
Then:
git branch -avv
(to see if you do have fetched an origin/master
branch)
Finally, use git switch
instead of the confusing git checkout
, with Git 2.23+ (August 2019).
git switch -c test --track origin/master
Since the question is how to replace ALL whitespaces
UPDATE `table`
SET `col_name` = REPLACE
(REPLACE(REPLACE(`col_name`, ' ', ''), '\t', ''), '\n', '');
As per the syntax
function [name]([param1[ = defaultValue1 ][, ..., paramN[ = defaultValueN ]]]) {
statements
}
you can define the default value of formal parameters. and also check undefined value by using typeof function.
You don't encode the entire URL, only parts of it that come from "unreliable sources".
Java:
String query = URLEncoder.encode("apples oranges", "utf-8");
String url = "http://stackoverflow.com/search?q=" + query;
Kotlin:
val query: String = URLEncoder.encode("apples oranges", "utf-8")
val url = "http://stackoverflow.com/search?q=$query"
Alternatively, you can use Strings.urlEncode(String str) of DroidParts that doesn't throw checked exceptions.
Or use something like
String uri = Uri.parse("http://...")
.buildUpon()
.appendQueryParameter("key", "val")
.build().toString();
There are many way to do the string aggregation, but the easiest is a user defined function. Try this for a way that does not require a function. As a note, there is no simple way without the function.
This is the shortest route without a custom function: (it uses the ROW_NUMBER() and SYS_CONNECT_BY_PATH functions )
SELECT questionid,
LTRIM(MAX(SYS_CONNECT_BY_PATH(elementid,','))
KEEP (DENSE_RANK LAST ORDER BY curr),',') AS elements
FROM (SELECT questionid,
elementid,
ROW_NUMBER() OVER (PARTITION BY questionid ORDER BY elementid) AS curr,
ROW_NUMBER() OVER (PARTITION BY questionid ORDER BY elementid) -1 AS prev
FROM emp)
GROUP BY questionid
CONNECT BY prev = PRIOR curr AND questionid = PRIOR questionid
START WITH curr = 1;
You have two options for this:
1.) make changes in the settings.xml add this in first tag
<localRepository>C:/Users/admin/.m2/repository</localRepository>
2.) use the -o tag for offline command.
mvn -o clean install -DskipTests=true
mvn -o jetty:run
to stop a docker process and release the ports, first use ctrl-c to leave the exit the container then use docker ps to find the list of running containers. Then you can use the docker container stop to stop that process and release its ports. The container name you can find from the docker ps command which gives the name in the name column. Hope this solves your queries....
I know it's an old question but maybe someone can use this solution:
int size = 0; // Fill all bits with zero (0)
size = ~size; // Negate all bits, thus all bits are set to one (1)
So far we have -1 as result 'till size is a signed int.
size = (unsigned int)size >> 1; // Shift the bits of size one position to the right.
As Standard says, bits that are shifted in are 1 if variable is signed and negative and 0 if variable would be unsigned or signed and positive.
As size is signed and negative we would shift in sign bit which is 1, which is not helping much, so we cast to unsigned int, forcing to shift in 0 instead, setting the sign bit to 0 while letting all other bits remain 1.
cout << size << endl; // Prints out size which is now set to maximum positive value.
We could also use a mask and xor but then we had to know the exact bitsize of the variable. With shifting in bits front, we don't have to know at any time how many bits the int has on machine or compiler nor need we include extra libraries.
I also just found out how to do this with the Excel Name Manager (Formulas > Defined Names Section > Name Manager).
You can define a variable that doesn't have to "live" within a cell and then you can use it in formulas.
adding HTTP headers using urllib2:
from the docs:
import urllib2
req = urllib2.Request('http://www.example.com/')
req.add_header('Referer', 'http://www.python.org/')
resp = urllib2.urlopen(req)
content = resp.read()
@modesty:
I wish there was a Mac version.
You can install the font on a Mac. I use it all the time, everywhere, without any problem. The only thing to pay attention for is to set nomacatsui
when working with GVIM, or better yet, switch to MacVim.
The fix for the heartbleed
vulnerability has been backported to 1.0.1e-16
by Red Hat for Enterprise Linux see, and this is therefore the official fix that CentOS ships.
Replacing OpenSSL with the latest version from upstream (i.e. 1.0.1g) runs the risk of introducing functionality changes which may break compatibility with applications/clients in unpredictable ways, causes your system to diverge from RHEL, and puts you on the hook for personally maintaining future updates to that package. By replacing openssl using a simple make config && make && make install means that you also lose the ability to use rpm to manage that package and perform queries on it (e.g. verifying all the files are present and haven't been modified or had permissions changed without also updating the RPM database).
I'd also caution that crypto software can be extremely sensitive to seemingly minor things like compiler options, and if you don't know what you're doing, you could introduce vulnerabilities in your local installation.
Try /*string with {}*/ string.trim().equalsIgnoreCase("{}"))
, maybe there is some extra spaces or something
The answers on this question are not only wrong, but dangerous. CTRL+ALT+SHIFT+B will not indent HTML but XML. Consider the following HTML code:
<span class="myClass"></span>
The function 'Notepad++ -> Plugins -> XmlTools -> Pretty print (Xml only with line breaks)' (CTRL+ALT+SHIFT+B) will transform this to:
<span class="myClass"/>
which will not be displayed correctly anymore by your browser! I strongly advice against using this function to indent HTML.
Instead use the plugin Tidy2. This will indent the HTML correctly without bad side-effects (but it will also create <html>, <head>, <body>, ...
elements around your code, if these are not there).
According to Nodejs Official Page, you can install&update new node version on windows using Chocolatey or Scoop
Using(Chocolatey):
cinst nodejs

Also you can download the Windows Installer directly from the nodejs.org web site
Building on Vitaliy's CSS and Mehmet's jQuery, I changed the a
tags to span
tags and incorporated some Glyphicons and badging into my take on a Bootstrap tree widget.
Example:
For extra credit, I've created a GitHub project to host the jQuery and LESS code that goes into adding this tree component to Bootstrap. Please see the project documentation at http://jhfrench.github.io/bootstrap-tree/docs/example.html.
Alternately, here is the LESS source to generate that CSS (the JS can be picked up from the jsFiddle):
@import "../../../external/bootstrap/less/bootstrap.less"; /* substitute your path to the bootstrap.less file */
@import "../../../external/bootstrap/less/responsive.less"; /* optional; substitute your path to the responsive.less file */
/* collapsable tree */

Several third-party libraries have classes encapsulating the concept of a range, such as Apache commons-lang's Range (and subclasses).
Using classes such as this you could express your constraint similar to:
if (new IntRange(0, 5).contains(orderBean.getFiles().size())
// (though actually Apache's Range is INclusive, so it'd be new Range(1, 4) - meh
with the added bonus that the range object could be defined as a constant value elsewhere in the class.
However, without pulling in other libraries and using their classes, Java's strong syntax means you can't massage the language itself to provide this feature nicely. And (in my own opinion), pulling in a third party library just for this small amount of syntactic sugar isn't worth it.
This is the easiest one
You can define your modal behavior, defining data-keyboard and data-backdrop.
<div id="modal" class="modal hide fade in" data-keyboard="false" data-backdrop="static">
...the correct answer is to use async/await with the native fs
promises module included in node. Upgrade to Node.js 10 or 11 (already supported by major cloud providers) and do this:
const fs = require('fs').promises;
// This must run inside a function marked `async`:
const file = await fs.readFile('filename.txt', 'utf8');
await fs.writeFile('filename.txt', 'test');
Do not use third-party packages and do not write your own wrappers, that's not necessary anymore.
Before Node 11.14.0
, you would still get a warning that this feature is experimental, but it works just fine and it's the way to go in the future. Since 11.14.0
, the feature is no longer experimental and is production-ready.
import
instead of require
?It works, too - but only in Node.js versions where this feature is not marked as experimental.
import { promises as fs } from 'fs';
(async () => {
await fs.writeFile('./test.txt', 'test', 'utf8');
})();
<textarea name='Status'> </textarea>
<input type='button' value='Status Update'>
You have few problems with your code like using .
for concatenation
Try this -
$(function () {
$('input').on('click', function () {
var Status = $(this).val();
$.ajax({
url: 'Ajax/StatusUpdate.php',
data: {
text: $("textarea[name=Status]").val(),
Status: Status
},
dataType : 'json'
});
});
});
The debug
module can be used to analyze variables. Be careful running the following command. In our setup it generates 444709 lines with 16MB:
ansible -m debug -a 'var=hostvars' localhost
I am not sure but it might be necessary to enable facts caching.
If you need just one host use the host name as a key for the hostvars
hash:
ansible -m debug -a 'var=hostvars.localhost' localhost
There is also a way to do this without loops using the DataTable.Compute Method. The following example comes from that page. You can see that the code used is pretty simple.:
private void ComputeBySalesSalesID(DataSet dataSet)
{
// Presumes a DataTable named "Orders" that has a column named "Total."
DataTable table;
table = dataSet.Tables["Orders"];
// Declare an object variable.
object sumObject;
sumObject = table.Compute("Sum(Total)", "EmpID = 5");
}
I must add that if you do not need to filter the results, you can always pass an empty string:
sumObject = table.Compute("Sum(Total)", "")
Sometimes other css conflicts as well - CSS priority issue.
to check, Go to your modal fade class on browser and then check if there is any custom file comes on top. such as .fade:not(.show)
where it was using its own information not the bootstrap. if you find then you have to change it to your needs .
Hope this helps.
In order to avoid dealing with these very boring issues, I advise you to always parse your data with the standard and unique SQL/ISO date format which is YYYY-MM-DD. Your queries will then work internationally, no matter what the date parameters are on your main server or on the querying clients (where local date settings might be different than main server settings)!
If I understand you correctly, you can use a combination of Series.isin()
and DataFrame.append()
:
In [80]: df1

2 1 0xdafL
3 0 0x21abL
4 4 0x1d14L
5 2 0x21abL
6 1 0x21abL
7 0 0xdafL
8 4 0x1d14L
9 1 0x21abL
In [81]: df2
Out[81]:

This is essentially the algorithm you described as "clunky", using idiomatic pandas
methods. Note the duplicate row indices. Also, note that this won't give you the expected output if df1
and df2
have no overlapping row indices, i.e., if
In [93]: df1.index & df2.index
Out[93]: Int64Index([], dtype='int64')
In fact, it won't give the expected output if their row indices are not equal.
If you want a list of only the object columns you could do:
non_numerics = [x for x in df.columns \
if not (df[x].dtype == np.float64 \
or df[x].dtype == np.int64)]
and then if you want to get another list of only the numerics:
numerics = [x for x in df.columns if x not in non_numerics]
Regarding your final bullet
make width fit the text
You can experiment with the .AutoSizeMode of your DataGridViewColumn, setting it to one of these values:
None
AllCells
AllCellsExceptHeader
DisplayedCells
DisplayedCellsExceptHeader
ColumnHeader

The Perl documentation comes with a nice collection of FAQs. Your question is frequently asked:
% perldoc -q duplicate
The answer, copy and pasted from the output of the command above, appears below:
Found in /usr/local/lib/perl5/5.10.0/pods/perlfaq4.pod How can I remove duplicate elements from a list or array? (contributed by brian d foy) Use a hash. When you think the words "unique" or "duplicated", think "hash keys". If you don't care about the order of the elements, you could just create the hash then extract the keys. It's not important how you create that hash: just that you use "keys" to get the unique elements. my %hash = map { $_, 1 } @array; # or a hash slice: @hash{ @array } = (); # or a foreach: $hash{$_} = 1 foreach ( @array ); my @unique = keys %hash; If you want to use a module, try the "uniq" function from "List::MoreUtils". In list context it returns the unique elements, preserving their order in the list. In scalar context, it returns the number of unique elements. use List::MoreUtils qw(uniq); my @unique = uniq( 1, 2, 3, 4, 4, 5, 6, 5, 7 ); # 1,2,3,4,5,6,7 my $unique = uniq( 1, 2, 3, 4, 4, 5, 6, 5, 7 ); # 7 You can also go through each element and skip the ones you've seen before. Use a hash to keep track. The first time the loop sees an element, that element has no key in %Seen. The "next" statement creates the key and immediately uses its value, which is "undef", so the loop continues to the "push" and increments the value for that key. The next time the loop sees that same element, its key exists in the hash and the value for that key is true (since it's not 0 or "undef"), so the next skips that iteration and the loop goes to the next element. my @unique = (); my %seen = (); foreach my $elem ( @array ) { next if $seen{ $elem }++; push @unique, $elem; } You can write this more briefly using a grep, which does the same thing. my %seen = (); my @unique = grep { ! $seen{ $_ }++ } @array;
I got this to work:
explicit conversion
public override object ReadJson(JsonReader reader, Type objectType, object existingValue,
JsonSerializer serializer)
{
var jsonObj = serializer.Deserialize<List<SomeObject>>(reader);
var conversion = jsonObj.ConvertAll((x) => x as ISomeObject);
return conversion;
}
Adding the default_url in routes not the right solution although, it works for some cases.
You've to set the default_url in each environment(development, test, production).
You need make these changes.
config/environments/development.rb
config.action_mailer.default_url_options =
{ :host => 'your-host-name' } #if it is local then 'localhost:3000'
config/environments/test.rb
config.action_mailer.default_url_options =
{ :host => 'your-host-name' } #if it is local then 'localhost:3000'
config/environments/development.rb
config.action_mailer.default_url_options =
{ :host => 'your-host-name' } #if it is local then 'localhost:3000'
I just want to add something here: changing the title via JavaScript is actually useful if you're updating a database via AJAX, so then the title changes without you having to refresh the page. The title actually changes via your server side scripting language, but having it change via JavaScript is just a usability and UI thing that makes the user experience more enjoyable and fluid.
Now, if you're changing the title via JavaScript just for the hell of it, then you should not be doing that.
It goes through the object as a key-value structure. Then it will add a new property named 'Active' and a sample value for this property ('Active) to every single object inside of this object. this code can be applied for both array of objects and object of objects.
Object.keys(Results).forEach(function (key){
Object.defineProperty(Results[key], "Active", { value: "the appropriate value"});
});

I've always used the SimpleXML functions built in to PHP to parse XML documents. It's one of the few generic parsers out there that has an intuitive structure to it, which makes it extremely easy to build a meaningful class for something specific like an RSS feed. Additionally, it will detect XML warnings and errors, and upon finding any you could simply run the source through something like HTML Tidy (as ceejayoz mentioned) to clean it up and attempt it again.
Consider this very rough, simple class using SimpleXML:
class BlogPost
{
var $date;
var $ts;
var $link;
var $title;
var $text;
}
class BlogFeed
{
var $posts = array();
function __construct($file_or_url)
{
$file_or_url = $this->resolveFile($file_or_url);
if (!($x = simplexml_load_file($file_or_url)))
return;
foreach ($x->channel->item as $item)
{
$post = new BlogPost();
$post->date = (string) $item->pubDate;
$post->ts = strtotime($item->pubDate);
$post->link = (string) $item->link;
$post->title = (string) $item->title;
$post->text = (string) $item->description;
// Create summary as a shortened body and remove images,
// extraneous line breaks, etc.
$post->summary = $this->summarizeText($post->text);
$this->posts[] = $post;
}
}
private function resolveFile($file_or_url) {
if (!preg_match('|^https?:|', $file_or_url))
$feed_uri = $_SERVER['DOCUMENT_ROOT'] .'/shared/xml/'. $file_or_url;
else
$feed_uri = $file_or_url;
return $feed_uri;
}
private function summarizeText($summary) {
$summary = strip_tags($summary);
// Truncate summary line to 100 characters
$max_len = 100;
if (strlen($summary) > $max_len)
$summary = substr($summary, 0, $max_len) . '...';
return $summary;
}
}
Update answer: Android 8.0 (API level 26) introduces a new feature, Fonts in XML. just use the Fonts in XML feature on devices running Android 4.1 (API level 16) and higher, use the Support Library 26.

Old answer
There are two ways to customize fonts :
!!! my custom font in assets/fonts/iran_sans.ttf
Way 1 :
Refrection Typeface.class ||| best way
call FontsOverride.setDefaultFont() in class extends Application, This code will cause all software fonts to be changed, even Toasts fonts
AppController.java
public class AppController extends Application {
@Override
public void onCreate() {
super.onCreate();
//Initial Font
FontsOverride.setDefaultFont(getApplicationContext(), "MONOSPACE", "fonts/iran_sans.ttf");
}
}
FontsOverride.java
public class FontsOverride {
public static void setDefaultFont(Context context, String staticTypefaceFieldName, String fontAssetName) {
final Typeface regular = Typeface.createFromAsset(context.getAssets(), fontAssetName);
replaceFont(staticTypefaceFieldName, regular);
}
private static void replaceFont(String staticTypefaceFieldName, final Typeface newTypeface) {
try {
final Field staticField = Typeface.class.getDeclaredField(staticTypefaceFieldName);
staticField.setAccessible(true);
staticField.set(null, newTypeface);
} catch (NoSuchFieldException e) {
e.printStackTrace();
} catch (IllegalAccessException e) {
e.printStackTrace();
}
}
}
Way 2: use setTypeface
for special view just call setTypeface() to change font.
CTextView.java
public class CTextView extends TextView {
public CTextView(Context context) {
super(context);
init(context,null);
}
public CTextView(Context context, @Nullable AttributeSet attrs) {
super(context, attrs);
init(context,attrs);
}
public CTextView(Context context, @Nullable AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
init(context,attrs);
}
@RequiresApi(api = Build.VERSION_CODES.LOLLIPOP)
public CTextView(Context context, @Nullable AttributeSet attrs, int defStyleAttr, int defStyleRes) {
super(context, attrs, defStyleAttr, defStyleRes);
init(context,attrs);
}
public void init(Context context, @Nullable AttributeSet attrs) {
if (isInEditMode())
return;
// use setTypeface for change font this view
setTypeface(FontUtils.getTypeface("fonts/iran_sans.ttf"));
}
}
FontUtils.java
public class FontUtils {
private static Hashtable<String, Typeface> fontCache = new Hashtable<>();
public static Typeface getTypeface(String fontName) {
Typeface tf = fontCache.get(fontName);
if (tf == null) {
try {
tf = Typeface.createFromAsset(AppController.getInstance().getApplicationContext().getAssets(), fontName);
} catch (Exception e) {
e.printStackTrace();
return null;
}
fontCache.put(fontName, tf);
}
return tf;
}
}
