Replace double quotes with single ones:
INSERT
INTO MY.LOGFILE
(id,severity,category,logdate,appendername,message,extrainfo)
VALUES (
'dee205e29ec34',
'FATAL',
'facade.uploader.model',
'2013-06-11 17:16:31',
'LOGDB',
NULL,
NULL
)
In SQL, double quotes are used to mark identifiers, not string constants.
You can use GNU awk:
$ cat hta
RewriteCond %{HTTP_HOST} !^www\.mysite\.net$
RewriteRule (.*) http://www.mysite.net/$1 [R=301,L]
$ gawk 'match($0, /.*(http.*?)\$/, m) { print m[1]; }' < hta
http://www.mysite.net/
Since the main
method is static
and the fxn()
method is not, you can't call the method without first creating a Two
object. So either you change the method to:
public static int fxn(int y) {
y = 5;
return y;
}
or change the code in main
to:
Two two = new Two();
x = two.fxn(x);
Read more on static
here in the Java Tutorials.
What context/language? Some languages use /
as the pattern delimiter, so yes, you need to escape it, depending on which language/context. You escape it by putting a backward slash in front of it: \/
For some languages (like PHP) you can use other characters as the delimiter and therefore you don't need to escape it. But AFAIK in all languages, the only special significance the /
has is it may be the designated pattern delimiter.
As i've mentioned in other, similar questions, you may want to consider compressing the data as the default java serialization is a bit verbose. you do this by putting a GZIPInput/OutputStream between the Object streams and the Byte streams.
It's not a valid format, however "Tue, 1 Jan 2008 00:00:00 GMT" is.
The documentation says like this:
A string that includes time zone information and conforms to ISO 8601. For example, the first of the following two strings designates the Coordinated Universal Time (UTC); the second designates the time in a time zone seven hours earlier than UTC:
2008-11-01T19:35:00.0000000Z
A string that includes the GMT designator and conforms to the RFC 1123 time format. For example:
Sat, 01 Nov 2008 19:35:00 GMT
A string that includes the date and time along with time zone offset information. For example:
03/01/2009 05:42:00 -5:00
The latest version of Genymotion (2.10.0 onwards) now allows you to install GApps from the emulator toolbar:

Let us say your table has following fields:
( pk_id int not null auto_increment primary key,
col1 int,
col2 varchar(10)
)
then, to copy values from one row to the other row with new key value, following query may help
insert into my_table( col1, col2 ) select col1, col2 from my_table where pk_id=?;
This will generate a new value for pk_id
field and copy values from col1
, and col2
of the selected row.
You can extend this sample to apply for more fields in the table.
UPDATE:
In due respect to the comments from JohnP and Martin -
We can use temporary table to buffer first from main table and use it to copy to main table again. Mere update of pk reference field in temp table will not help as it might already be present in the main table. Instead we can drop the pk field from the temp table and copy all other to the main table.
With reference to the answer by Tim Ruehsen in the referred posting:
CREATE TEMPORARY TABLE tmp SELECT * from my_table WHERE ...;
ALTER TABLE tmp drop pk_id; # drop autoincrement field
# UPDATE tmp SET ...; # just needed to change other unique keys
INSERT INTO my_table SELECT 0,tmp.* FROM tmp;
DROP TEMPORARY TABLE tmp;
Hope this helps.
The default constructor has no arguments. You need to specify a constructor:
public Friends( String firstName, String age) { ... }
I had the same issue with XUnit. The problem was with my database connection. Check your connection string is correct or not.
If you installed with brew, try brew uninstall yarn
at terminal prompt. Also remember to remove yarn path info in your .bash_profile
.
No need to use these commands .. you can directly use the nexus web Interface in order to upload your JAR using GAV parameters.
So it is very simple.
To the first part of your question - yes, browsers cache css files (if this is not disabled by browser's configuration). Many browsers have key combination to reload a page without a cache. If you made changes to css and want users to see them immediately instead of waiting next time when browser reloads the files without caching, you can change the way CSS ir served by adding some parameters to the url like this:
/style.css?modified=20012009
You could use 'corrplot' package.
d <- data.frame(x1=rnorm(10),
x2=rnorm(10),
x3=rnorm(10))
M <- cor(d) # get correlations
library('corrplot') #package corrplot
corrplot(M, method = "circle") #plot matrix
More information here: http://cran.r-project.org/web/packages/corrplot/vignettes/corrplot-intro.html
<script>
window.open('http://www.example.com?ReportID=1', '_blank');
</script>
The second parameter is optional and is the name of the target window.
Two answers I can think of... neither is particularly as pleasant as just having a concatenation operator.
First, use an NSMutableString
, which has an appendString
method, removing some of the need for extra temp strings.
Second, use an NSArray
to concatenate via the componentsJoinedByString
method.
When you run WScript.Shell it runs under the local system account, this account has full rights on the machine, but no rights in Active Directory.
The main answer worked for me but made the app extremely unresponsive in IE, so I used a timer as suggested. Code looks something like this ($(#contentColumn)
is the div that the JQGrid sits in):
function resizeGrids() {
var reportObjectsGrid = $("#ReportObjectsGrid");
reportObjectsGrid.setGridWidth($("#contentColumn").width());
};
var resizeTimer;
$(window).bind('resize', function () {
clearTimeout(resizeTimer);
resizeTimer = setTimeout(resizeGrids, 60);
});
Update: It’s been almost 5 years since I wrote the answer below; today I have a different perspective.
99% of the time when people use the term REST, they really mean HTTP; they could care less about “resources”, “representations”, “state transfers”, “uniform interfaces”, “hypermedia”, or any other constraints or aspects of the REST architecture style identified by Fielding. The abstractions provided by various REST frameworks are therefore confusing and unhelpful.
So: you want to send HTTP requests using Java in 2015. You want an API that is clear, expressive, intuitive, idiomatic, simple. What to use? I no longer use Java, but for the past few years the Java HTTP client library that has seemed the most promising and interesting is OkHttp. Check it out.
You can definitely interact with RESTful web services by using URLConnection
or HTTPClient to code HTTP requests.
However, it's generally more desirable to use a library or framework which provides a simpler and more semantic API specifically designed for this purpose. This makes the code easier to write, read, and debug, and reduces duplication of effort. These frameworks generally implement some great features which aren't necessarily present or easy to use in lower-level libraries, such as content negotiation, caching, and authentication.
Some of the most mature options are Jersey, RESTEasy, and Restlet.
I'm most familiar with Restlet, and Jersey, let's look at how we'd make a POST
request with both APIs.
Form form = new Form();
form.add("x", "foo");
form.add("y", "bar");
Client client = ClientBuilder.newClient();
WebTarget resource = client.target("http://localhost:8080/someresource");
Builder request = resource.request();
request.accept(MediaType.APPLICATION_JSON);
Response response = request.get();
if (response.getStatusInfo().getFamily() == Family.SUCCESSFUL) {
System.out.println("Success! " + response.getStatus());
System.out.println(response.getEntity());
} else {
System.out.println("ERROR! " + response.getStatus());
System.out.println(response.getEntity());
}
Form form = new Form();
form.add("x", "foo");
form.add("y", "bar");
ClientResource resource = new ClientResource("http://localhost:8080/someresource");
Response response = resource.post(form.getWebRepresentation());
if (response.getStatus().isSuccess()) {
System.out.println("Success! " + response.getStatus());
System.out.println(response.getEntity().getText());
} else {
System.out.println("ERROR! " + response.getStatus());
System.out.println(response.getEntity().getText());
}
Of course, GET requests are even simpler, and you can also specify things like entity tags and Accept
headers, but hopefully these examples are usefully non-trivial but not too complex.
As you can see, Restlet and Jersey have similar client APIs. I believe they were developed around the same time, and therefore influenced each other.
I find the Restlet API to be a little more semantic, and therefore a little clearer, but YMMV.
As I said, I'm most familiar with Restlet, I've used it in many apps for years, and I'm very happy with it. It's a very mature, robust, simple, effective, active, and well-supported framework. I can't speak to Jersey or RESTEasy, but my impression is that they're both also solid choices.
You can get to SIZES
by means of self.SIZES
(in an instance method) or cls.SIZES
(in a class method).
In any case, you will have to be explicit about where to find SIZES
. An alternative is to put SIZES
in the module containing the classes, but then you need to define all classes in a single module.
When you call figure
, simply number the plot.
x = arange(5)
y = np.exp(5)
plt.figure(0)
plt.plot(x, y)
z = np.sin(x)
plt.figure(1)
plt.plot(x, z)
w = np.cos(x)
plt.figure(0) # Here's the part I need
plt.plot(x, w)
Edit: Note that you can number the plots however you want (here, starting from 0
) but if you don't provide figure with a number at all when you create a new one, the automatic numbering will start at 1
("Matlab Style" according to the docs).
The answer of Pascal Thivent helped me out, too.
But if you manage your plugins within the <pluginManagement>

Here's a short answer
x=' ';
This will print one white space
print(x);
This will print 10 white spaces
print(10*x)
Print 10 whites spaces between Hello & World
print("Hello"+10*x+"world");
Tested!
In Windows -> control panel -> Region -> Additional Settings -> Time -> Short Time:
Format your time as HH:mm
in the format
hh = 12 hours
HH = 24 hours
mm = minutes
tt = AM or PM
so to get the required result the format should be HH:mm and not hh:mm tt
It is the same as in eclipse:
Ctrl + Shift + X
Ctrl + Shift + Y
Add below to the DateTime property

You can set the id of the body of the page to some value that represents the current page. Then for each element in the menu you set a class specific to that menu item. And within your CSS you can set up a rule that will highlight the menu item specifically...
That probably didn't make much sense, so here's an example:
<body id="index">
<div id="menu">
<ul>
<li class="index" ><a href="index.html">Index page</a></li>
<li class="page1" ><a href="page1.html">Page 1</a></li>
</ul>
</div> <!-- menu -->
</body>
In the page1.html, you would set the id of the body to: id="page1"
.
Finally in your CSS you have something like the following:
#index #menu .index, #page1 #menu .page1 {
font-weight: bold;
}
You would need to alter the ID for each page, but the CSS remains the same, which is important as the CSS is often cached and can require a forced refresh to update.
It's not dynamic, but it's one method that's simple to do, and you can just include
the menu html from a template file using PHP or similar.
require(str_repeat('../',(substr_count(getenv('SCRIPT_URL'),'/')-1))."/path/to/file.php");
I use this line of code. It goes back to the "top" of the site tree, then goes to the file desired.
For example, let's say i have this file tree:
domain.com/aaa/index.php
domain.com/bbb/ccc/ddd/index.php
domain.com/_resources/functions.php
I can include the functions.php file from wherever i am, just by copy pasting
require(str_repeat('../',(substr_count(getenv('SCRIPT_URL'),'/')-1))."/_resources/functions.php");
If you need to use this code many times, you may create a function that returns the str_repeat('../',(substr_count(getenv('SCRIPT_URL'),'/')-1))
part. Then just insert this function in the first file you include. I have an "initialize.php" file that i include at the very top of each php page and which contains this function. The next time i have to include files, i in fact just use the function (named path_back
):
require(path_back()."/_resources/another_php_file.php");
Using a custom attribute (implemented with a directive) is perhaps the cleanest way. Here's my version, based on @Josh and @sean's suggestions.
angular.module('mymodule', [])
// Click to navigate
// similar to <a href="#/partial"> but hash is not required,
// e.g. <div click-link="/partial">
.directive('clickLink', ['$location', function($location) {
return {
link: function(scope, element, attrs) {
element.on('click', function() {
scope.$apply(function() {
$location.path(attrs.clickLink);
});
});
}
}
}]);
It has some useful features, but I'm new to Angular so there's probably room for improvement.
You can set the line size as per the width of the window and set wrap off using the following command.
set linesize 160;
set wrap off;
I have used 160 as per my preference you can set it to somewhere between 100 - 200
and setting wrap will not your data and it will display the data properly.
Alternatively, you could just return false from the click event:
$('div.toggle').hide();
$('ul.product-info li a').click(function(event){
$(this).next('div').slideToggle(200);
+ return false;
});
Which would stop the A-Href being triggered.
Note however, for usability reasons, in an ideal world that href should still go somewhere, for the people whom want to open link in new tab ;)
Fairly simple process I am using SCSS obviously but you don't have to as it's just CSS in the end!

TreeViewItem tempItem = new TreeViewItem();
TreeViewItem tempItem1 = new TreeViewItem();
tempItem = (TreeViewItem) treeView1.Items.GetItemAt(0); // Selecting the first of the top level nodes
tempItem1 = (TreeViewItem)tempItem.Items.GetItemAt(0); // Selecting the first child of the first first level node
SelectedCategoryHeaderString = tempItem.Header.ToString(); // gets the header for the first top level node
SelectedCategoryHeaderString = tempItem1.Header.ToString(); // gets the header for the first child node of the first top level node
tempItem.IsExpanded = true; // will expand the first node

To read the memory at given addresses you should take a look at x
x/x $esp
for hex x/d $esp
for signed x/u $esp
for unsigned etc. x uses the format syntax, you could also take a look at the current instruction via x/i $eip
etc.
function getComboA(selectObject) {_x000D_
var value = selectObject.value; _x000D_
console.log(value);_x000D_
}
_x000D_
<select id="comboA" onchange="getComboA(this)">_x000D_
<option value="">Select combo</option>_x000D_
<option value="Value1">Text1</option>_x000D_
<option value="Value2">Text2</option>_x000D_
<option value="Value3">Text3</option>_x000D_
</select>
_x000D_
The above example gets you the selected value of combo box on OnChange event.
To match a string that contains only those characters (or an empty string), try
"^[a-zA-Z0-9_]*$"
This works for .NET regular expressions, and probably a lot of other languages as well.
Breaking it down:
^ : start of string
[ : beginning of character group
a-z : any lowercase letter
A-Z : any uppercase letter
0-9 : any digit
_ : underscore
] : end of character group
* : zero or more of the given characters
$ : end of string
If you don't want to allow empty strings, use + instead of *.
As others have pointed out, some regex languages have a shorthand form for [a-zA-Z0-9_]
. In the .NET regex language, you can turn on ECMAScript behavior and use \w
as a shorthand (yielding ^\w*$
or ^\w+$
). Note that in other languages, and by default in .NET, \w
is somewhat broader, and will match other sorts of Unicode characters as well (thanks to Jan for pointing this out). So if you're really intending to match only those characters, using the explicit (longer) form is probably best.
let
defines a "constant". Its value is set once and only once, though not necessarily when you declare it. For example, you use let
to define a property in a class that must be set during initialization:
class Person {
let firstName: String
let lastName: String
init(first: String, last: String) {
firstName = first
lastName = last
super.init()
}
}
With this setup, it's invalid to assign to firstName
or lastName
after calling (e.g.) Person(first:"Malcolm", last:"Reynolds")
to create a Person
instance.
You must define a type for all variables (let
or var
) at compile time, and any code that attempts to set a variable may only use that type (or a subtype). You can assign a value at run time, but its type must be known at compile time.
You could also write it a little more cleaner using updateOne & $set, plus async/await.
const updateUser = async (newUser) => {
try {
await User.updateOne({ username: oldUsername }, {
$set: {
username: newUser.username,
password: newUser.password,
rights: newUser.rights
}
})
} catch (err) {
console.log(err)
}
}
Since you don't need the resulting document, you can just use updateOne instead of findOneAndUpdate.
Here's a good discussion about the difference: MongoDB 3.2 - Use cases for updateOne over findOneAndUpdate
Mock is a method/object that simulates the behavior of a real method/object in controlled ways. Mock objects are used in unit testing.
Often a method under a test calls other external services or methods within it. These are called dependencies. Once mocked, the dependencies behave the way we defined them.
With the dependencies being controlled by mocks, we can easily test the behavior of the method that we coded. This is Unit testing.
Take a look at DCEVM, it's a modification of the HotSpot VM that allows unlimited class redefinitions at runtime. You can add/remove fields and methods and change the super types of a class at runtime.
The binaries available on the original site are limited to Java 6u25 and to early versions of Java 7. The project has been forked on Github and supports recent versions of Java 7 and 8. The maintainer provides binaries for 32/64 bits VMs on Windows/Linux. Starting with Java 11 the project moved to a new GitHub repository and now also provides binaries for OS X.
DCEVM is packaged for Debian and Ubuntu, it's conveniently integrated with OpenJDK and can be invoked with java -dcevm
. The name of the package depends on the version of the default JDK:
I have this set up in my .vimrc:
highlight OverLength ctermbg=red ctermfg=white guibg=#592929
match OverLength /\%81v.\+/
This highlights the background in a subtle red for text that goes over the 80 column limit (subtle in GUI mode, anyway - in terminal mode it's less so).
This line of code works for me
$("#datepicker").datepicker("option", "dateFormat", "dd/mm/yy");
you can change the id #datepicker with the class .input-group.date of course
>>> l = [22, 13, 45, 50, 98, 69, 43, 44, 1]
>>> [x+1 if x >= 45 else x+5 for x in l]
[27, 18, 46, 51, 99, 70, 48, 49, 6]
Do-something if <condition>
, else do-something else.
You can get the value by using the checked
property.
var rates = document.getElementsByName('rate');
var rate_value;
for(var i = 0; i < rates.length; i++){
if(rates[i].checked){
rate_value = rates[i].value;
}
}
Bootstrap will add or remove a css "modal-open"
to the <body>
tag when we open or close a modal. So if you open multiple modal and then close arbitrary one, the modal-open css will be removed from the body tag.
But the scroll effect depend on the attribute "overflow-y: auto;"
defined in modal-open
Try add jQuery
to your project, like
npm i jquery --save
or if you use bower
bower i jquery --save
then
import $ from 'jquery';
just use printf
instead of
repo forall -c '....$variable'
use printf to replace the variable token with the expanded variable.
For example:
template='.... %s'
repo forall -c $(printf "${template}" "${variable}")
You could use PHP's unlink() method just as @Khan suggested.
But if you want to do it the Laravel way, use the File::delete() method instead.
// Delete a single file
File::delete($filename);
// Delete multiple files
File::delete($file1, $file2, $file3);
// Delete an array of files
$files = array($file1, $file2);
File::delete($files);
And don't forget to add at the top:
use Illuminate\Support\Facades\File;
git reset --hard HEAD
git fetch --all
git reset --hard origin/your_branch
After hours searching on web for simple tool, i realized i didn't look in Ubuntu Software Center. Here is a free solution i found: http://torasql.com/ They claim to have a version for Windows also, but I'm only using it under Ubuntu.
Edit: 2015-Feb-05 If you need Windows tool, TOAD is perfect and free: http://software.dell.com/products/toad-for-mysql/
Here is a really nice example of a pythonic way to do that:
import json
import psycopg2
def db(database_name='pepe'):
return psycopg2.connect(database=database_name)
def query_db(query, args=(), one=False):
cur = db().cursor()
cur.execute(query, args)
r = [dict((cur.description[i][0], value) \
for i, value in enumerate(row)) for row in cur.fetchall()]
cur.connection.close()
return (r[0] if r else None) if one else r
my_query = query_db("select * from majorroadstiger limit %s", (3,))
json_output = json.dumps(my_query)
You get an array of JSON objects:
>>> json_output
'[{"divroad": "N", "featcat": null, "countyfp": "001",...
Or with the following:
>>> j2 = query_db("select * from majorroadstiger where fullname= %s limit %s",\
("Mission Blvd", 1), one=True)
you get a single JSON object:
>>> j2 = json.dumps(j2)
>>> j2
'{"divroad": "N", "featcat": null, "countyfp": "001",...
document.getElementById("id").innerHTML == "" || null
or
$("element").html() == "" || null
The solution @miki725 is absolutely correct. Alternatively, if you would like to use the args
attribute as opposed to kwargs
, then you can simply modify your code as follows:
project_id = 4
reverse('edit_project', args=(project_id,))
An example of this can be found in the documentation. This essentially does the same thing, but the attributes are passed as arguments. Remember that any arguments that are passed need to be assigned a value before being reversed. Just use the correct namespace, which in this case is 'edit_project'
.
The object your method decompressGZIP()
needs is a byte[]
.
So the basic, technical answer to the question you have asked is:
byte[] b = string.getBytes();
byte[] b = string.getBytes(Charset.forName("UTF-8"));
byte[] b = string.getBytes(StandardCharsets.UTF_8); // Java 7+ only
However the problem you appear to be wrestling with is that this doesn't display very well. Calling toString()
will just give you the default Object.toString()
which is the class name + memory address. In your result [B@38ee9f13
, the [B
means byte[]
and 38ee9f13
is the memory address, separated by an @
.
For display purposes you can use:
Arrays.toString(bytes);
But this will just display as a sequence of comma-separated integers, which may or may not be what you want.
To get a readable String
back from a byte[]
, use:
String string = new String(byte[] bytes, Charset charset);
The reason the Charset
version is favoured, is that all String
objects in Java are stored internally as UTF-16. When converting to a byte[]
you will get a different breakdown of bytes for the given glyphs of that String
, depending upon the chosen charset.

My solution:
Change the downloadPath accordingly to where you want your file to be saved. Feel free to use the absolute path too for your usage.
Save the below as downloadFile.py.
Usage: python downloadFile.py url-of-the-file-to-download new-file-name.extension
Remember to add an extension!
Example usage: python downloadFile.py http://www.google.co.uk google.html
import requests
import sys
import os
def downloadFile(url, fileName):
with open(fileName, "wb") as file:
response = requests.get(url)
file.write(response.content)
scriptPath = sys.path[0]

In the way that you're doing things, it won't happen. You're changing the background image of the image, which is being blocked by the original image. Changing the height and width also won't happen. To change the src attribute of the image, you would need Javascript or a Javascript Library such as jQuery. You could however, change the image to a simple div (text) box, and have a background image that changes on hover, even though the div box itself will be empty. Here's how.
<div id="emptydiv"></div>
#emptydiv {
background-image: url("LibraryHover.png");
height: 70px;
width: 120px;
}
#emptydiv:hover {
background-image: url("LibraryHoverTrans.png");
height: 700px;
width: 1200px;
}
I hope this is what you're asking for :)
If you want to get a String representation of the objects in your array, then yes, there is no other way to do it.
If you know your Object array contains Strings only, you may also do (instread of calling toString()):
for (int i=0;i<String_Array.length;i++) String_Array[i]= (String) Object_Array[i];
The only case when you could use the cast to String[] of the Object_Array would be if the array it references would actually be defined as String[] , e.g. this would work:
Object[] o = new String[10];
String[] s = (String[]) o;

By default mysqldump
always creates the CREATE DATABASE IF NOT EXISTS db_name;
statement at the beginning of the dump file.
[EDIT] Few things about the mysqldump
file and it's options:
--all-databases
, -A
Dump all tables in all databases. This is the same as using the --databases
option and naming all the databases on the command line.
--add-drop-database
Add a DROP DATABASE
statement before each CREATE DATABASE
statement. This option is typically used in conjunction with the --all-databases
or --databases
option because no CREATE DATABASE
statements are written unless one of those options is specified.
--databases
, -B
Dump several databases. Normally, mysqldump
treats the first name argument on the command line as a database name and following names as table names. With this option, it treats all name arguments as database names. CREATE DATABASE
and USE
statements are included in the output before each new database.
--no-create-db
, -n
This option suppresses the CREATE DATABASE
statements that are otherwise included in the output if the --databases
or --all-databases
option is given.
Some time ago, there was similar question actually asking about not having such statement on the beginning of the file (for XML file). Link to that question is here.
So to answer your question:
--add-drop-database
option in your mysqldump
statement.--databases
or --all-databases
and the CREATE DATABASE
syntax will be added

very old question, i know. but with the new f-strings (starting from python 3.6) there are fresh options. so here for completeness:
from datetime import datetime
dt = datetime.now()
# str.format
strg = '{:%B %d, %Y}'.format(dt)
print(strg) # July 22, 2017
# datetime.strftime
strg = dt.strftime('%B %d, %Y')
print(strg) # July 22, 2017
# f-strings in python >= 3.6
strg = f'{dt:%B %d, %Y}'
print(strg) # July 22, 2017
strftime()
and strptime()
Behavior explains what the format specifiers mean.

Will need to save the beginning center of the image view:
var panBegin: CGPoint.zero
Then update the new center using a transform:
if recognizer.state == .began {
panBegin = imageView!.center
} else if recognizer.state == .ended {
panBegin = CGPoint.zero
} else if recognizer.state == .changed {
let translation = recognizer.translation(in: view)
let panOffsetTransform = CGAffineTransform( translationX: translation.x, y: translation.y)
imageView!.center = panBegin.applying(panOffsetTransform)
}
For users working with the Genesis framework.
Add the following to your child theme functions.php
add_action( 'genesis_before', 'script_urls' );
function script_urls() {
?>
<script type="text/javascript">
var stylesheetDir = '<?= get_bloginfo("stylesheet_directory"); ?>';
</script>
<?php
}
And use that variable to set the relative url in your script. For example:
Reset.style.background = " url('"+stylesheetDir+"/images/searchfield_clear.png') ";
If you are using angular-cli
, then you can check it easily by typing
ng -v
or ng v
in Angular 8, in Terminal or Bash. Note: Run the command within the project directory.
You should get something like this:

node: 7.4.0
os: darwin x64
@angular/common: 2.4.3
@angular/compiler: 2.4.3
@angular/core: 2.4.3
@angular/forms: 2.4.3
@angular/http: 2.4.3
@angular/platform-browser: 2.4.3
@angular/platform-browser-dynamic: 2.4.3
@angular/router: 3.4.3
@angular/compiler-cli: 2.4.3

Given the fact that you can switch to origin/master
(though in detached state) while having your network cable unplugged, it must be a local representation of the master
branch at origin
.
I just dealt with this same issue. Make sure your query lists the full source name, using no shortcuts. Visual Studio can recognize the shortcuts, but your reporting services application may not be able to recognize which tables your data should be coming from. Hope that helps.
Application.Exit()
kills your application but there are some instances that it won't close the application.
End
is better than Application.Exit()
.
I like the build-in pathlib libary because of quick options like directory= Path.cwd()
Together with opencv it's quite easy to read pngs to numpy arrays.
In this example you can even check the prefix of the image.
from pathlib import Path
import cv2
prefix = "p00"
suffix = ".png"
directory= Path.cwd()
file_names= [subp.name for subp in directory.rglob('*') if (prefix in subp.name) & (suffix == subp.suffix)]
file_names.sort()
print(file_names)
all_frames= []
for file_name in file_names:
file_path = str(directory / file_name)
frame=cv2.imread(file_path)
all_frames.append(frame)
print(type(all_frames[0]))
print(all_frames[0] [1][1])
Output:
['p000.png', 'p001.png', 'p002.png', 'p003.png', 'p004.png', 'p005.png', 'p006.png', 'p007.png', 'p008.png', 'p009.png']

If you don't have any version of SQLServerManagerXX.msc, then you simply do not have it installed. I noticed it does not come with SQL server management studio 2019.
It's available (client-connectivity tools) in the SQL Server Express edition or SQL Server Developer edition which is good for dev/test (non-production) usage.
Now, i'm being told that this will terminate the session (or is it all sessions?) in the 15th minute of use, regardless their activity.
This is wrong. It will just kill the session when the associated client (webbrowser) has not accessed the website for more than 15 minutes. The activity certainly counts, exactly as you initially expected, seeing your attempt to solve this.
The HttpSession#setMaxInactiveInterval()
doesn't change much here by the way. It does exactly the same as <session-timeout>
in web.xml
, with the only difference that you can change/set it programmatically during runtime. The change by the way only affects the current session instance, not globally (else it would have been a static
method).
To play around and experience this yourself, try to set <session-timeout>
to 1 minute and create a HttpSessionListener
like follows:
@WebListener
public class HttpSessionChecker implements HttpSessionListener {
public void sessionCreated(HttpSessionEvent event) {
System.out.printf("Session ID %s created at %s%n", event.getSession().getId(), new Date());
}
public void sessionDestroyed(HttpSessionEvent event) {
System.out.printf("Session ID %s destroyed at %s%n", event.getSession().getId(), new Date());
}
}
(if you're not on Servlet 3.0 yet and thus can't use @WebListener
, then register in web.xml
as follows):
<listener>
<listener-class>com.example.HttpSessionChecker</listener-class>
</listener>
Note that the servletcontainer won't immediately destroy sessions after exactly the timeout value. It's a background job which runs at certain intervals (e.g. 5~15 minutes depending on load and the servletcontainer make/type). So don't be surprised when you don't see destroyed
line in the console immediately after exactly one minute of inactivity. However, when you fire a HTTP request on a timed-out-but-not-destroyed-yet session, it will be destroyed immediately.
OK, so we have to do splitting as you already got the answer I would generalize it.
If you want to split any string by spaces, delimiter(special chars).
First, remove the leading space as they create most of the issues.
str1 = " Hello I'm your String ";
str2 = " Are you serious about this question_ boy, aren't you? ";
First remove the leading space which can be space, tab etc.
String s = str1.replaceAll("^\\s+","");//starting with whitespace one or more
Now if you want to split by space or any special char.
String[] sa = s.split("[^\\w]+");//split by any non word char
But as w contains [a-zA-Z_0-9] ,so if you want to split by underscore(_) also use
String[] sa = s.split("[!,? ._'@]+");//for str2 after removing leading space
I use let
to test my HTTP 404 responses in my API specs using contexts.
To create the resource, I use let!
. But to store the resource identifier, I use let
. Take a look how it looks like:
let!(:country) { create(:country) }
let(:country_id) { country.id }
before { get "api/countries/#{country_id}" }
it 'responds with HTTP 200' { should respond_with(200) }
context 'when the country does not exist' do
let(:country_id) { -1 }
it 'responds with HTTP 404' { should respond_with(404) }
end
That keeps the specs clean and readable.
The simplest approach is to use a multitouch JavaScript library like Hammer.js. Then you can write code like:
canvas
.hammer({prevent_default: true})
.bind('doubletap', function(e) { // And double click
// Zoom-in
})
.bind('dragstart', function(e) { // And mousedown
// Get ready to drag
})
.bind('drag', function(e) { // And mousemove when mousedown
// Pan the image
})
.bind('dragend', function(e) { // And mouseup
// Finish the drag
});
And you can keep going. It supports tap, double tap, swipe, hold, transform (i.e., pinch) and drag. The touch events also fire when equivalent mouse actions happen, so you don't need to write two sets of event handlers. Oh, and you need the jQuery plugin if you want to be able to write in the jQueryish way as I did.
Thanks merv. I started tinkering around boostrap.js but your answer is a quick and clean workaround. Here's what I ended up using in my code.
$('#modal-item').on('hidden', function() {
$(this).removeData('modal');
});

How To Fix The Broken Icon Links (blank.gif, text.gif, etc.)
Unfortunately as previously mentioned, simply adding a virtual host to your project doesn't fix the broken icon links.
The Problem:
WAMP/Apache does not change the directory reference for the icons to your respective installation directory. It is statically set to "c:/Apache24/icons" and 99.9% of users Apache installation does not reside here. Especially with WAMP.
The Fix:
Find your Apache icons directory! Typically it will be located here: "c:/wamp/bin/apache/apache2.4.9/icons". However your mileage may vary depending on your installation and if your Apache version is different, then your path will be different as well.\
Open up httpd-autoindex.conf in your favorite editor. This file can usually be found here: "C:\wamp\bin\apache\apache2.4.9\conf\extra\httpd-autoindex.conf". Again, if your Apache version is different, then so will this path.
Find this definition (usually located near the top of the file):
Alias /icons/ "c:/Apache24/icons/"
<Directory "c:/Apache24/icons">
Options Indexes MultiViews
AllowOverride None
Require all granted
</Directory>
Replace the "c:/Apache24/icons/" directories with your own. IMPORTANT You MUST have a trailing forward slash in the first directory reference. The second directory reference must have no trailing slash. Your results should look similar to this. Again, your directory may differ:
Alias /icons/ "c:/wamp/bin/apache/apache2.4.9/icons/"
<Directory "c:/wamp/bin/apache/apache2.4.9/icons">
Options Indexes MultiViews
AllowOverride None
Require all granted
</Directory>
Restart your Apache server and enjoy your cool icons!
addEventListener
can add multiple events, whereas with onclick
this cannot be done.onclick
can be added as an HTML
attribute, whereas an addEventListener
can only be added within <script>
elements.addEventListener
can take a third argument which can stop the event propagation.Both can be used to handle events. However, addEventListener
should be the preferred choice since it can do everything onclick
does and more. Don't use inline onclick
as HTML attributes as this mixes up the javascript and the HTML which is a bad practice. It makes the code less maintainable.
For more complex DataFrames that have a Multi-Index (say "Stock" and "Date") and one wants to remove the last row for each Stock not just the last row of the last Stock, then the solution reads:
# To remove last n rows
df = df.groupby(level='Stock').apply(lambda x: x.head(-1)).reset_index(0, drop=True)
# To remove first n rows
df = df.groupby(level='Stock').apply(lambda x: x.tail(-1)).reset_index(0, drop=True)
As the groupby()
is adding an additional level to the Multi-Index we just drop it at the end using reset_index()
. The resulting df keeps the same type of Multi-Index as before the operation.
The most important thing here is consistency. That said, I follow the GTK+ coding convention, which can be summarized as follows:
MAX_BUFFER_SIZE
, TRACKING_ID_PREFIX
.GtkWidget
, TrackingOrder
.gtk_widget_show()
, tracking_order_process()
.GtkWidget *foo
, TrackingOrder *bar
._refrobnicate_data_tables()
, _destroy_cache()
.You could try making your div float:
.thatSetsABackgroundWithAnIcon{
float:left;
}
Alternativelly, use inline-block:
.thatSetsABackgroundWithAnIcon{
display:inline-block;
}
Working example of the inline-block method:
table,_x000D_
th,_x000D_
td {_x000D_
border: 1px solid black;_x000D_
}
_x000D_
<table>_x000D_
<tr>_x000D_
<td>_x000D_
<div style="border:1px solid red; height:100%; display:inline-block;">_x000D_
I want cell to be the full height_x000D_
</div>_x000D_
</td>_x000D_
<td>_x000D_
This cell_x000D_
<br/>is higher_x000D_
<br/>than the_x000D_
<br/>first one_x000D_
</td>_x000D_
</tr>_x000D_
</table>
_x000D_
Okay, A housemate took a look at it and figured it out:
func addCategory() {
var popoverContent = self.storyboard?.instantiateViewControllerWithIdentifier("NewCategory") as UIViewController
var nav = UINavigationController(rootViewController: popoverContent)
nav.modalPresentationStyle = UIModalPresentationStyle.Popover
var popover = nav.popoverPresentationController
popoverContent.preferredContentSize = CGSizeMake(500,600)
popover.delegate = self
popover.sourceView = self.view
popover.sourceRect = CGRectMake(100,100,0,0)
self.presentViewController(nav, animated: true, completion: nil)
}
That's the way.
You don't talk to the popover itself anymore, you talk to the view controller inside of it to set the content size, by calling the property preferredContentSize
You will get the proxy host and port from your server administrator or support.
After that set up
npm config set http_proxy http://username:[email protected]:itsport npm config set proxy http://username:[email protected]:itsport If there any special character in password try with % urlencode. Eg:- pound(hash) shuold be replaced by %23.
This worked for me...
Brynner Ferreira, has brought a good point: storing a sibling key where expiration info resides. This way, if you have a large amount of keys, or if your values are large Json objects, you don't need to parse them to access the timestamp.
here follows an improved version:
/* removeStorage: removes a key from localStorage and its sibling expiracy key
params:
key <string> : localStorage key to remove
returns:
<boolean> : telling if operation succeeded
*/
function removeStorage(name) {
try {
localStorage.removeItem(name);
localStorage.removeItem(name + '_expiresIn');
} catch(e) {
console.log('removeStorage: Error removing key ['+ key + '] from localStorage: ' + JSON.stringify(e) );
return false;
}
return true;
}
/* getStorage: retrieves a key from localStorage previously set with setStorage().
params:
key <string> : localStorage key
returns:
<string> : value of localStorage key
null : in case of expired key or failure
*/
function getStorage(key) {
var now = Date.now(); //epoch time, lets deal only with integer
// set expiration for storage
var expiresIn = localStorage.getItem(key+'_expiresIn');
if (expiresIn===undefined || expiresIn===null) { expiresIn = 0; }
if (expiresIn < now) {// Expired
removeStorage(key);
return null;
} else {
try {
var value = localStorage.getItem(key);
return value;
} catch(e) {
console.log('getStorage: Error reading key ['+ key + '] from localStorage: ' + JSON.stringify(e) );
return null;
}
}
}
/* setStorage: writes a key into localStorage setting a expire time
params:
key <string> : localStorage key
value <string> : localStorage value
expires <number> : number of seconds from now to expire the key
returns:
<boolean> : telling if operation succeeded
*/
function setStorage(key, value, expires) {
if (expires===undefined || expires===null) {
expires = (24*60*60); // default: seconds for 1 day
} else {
expires = Math.abs(expires); //make sure it's positive
}
var now = Date.now(); //millisecs since epoch time, lets deal only with integer
var schedule = now + expires*1000;
try {
localStorage.setItem(key, value);
localStorage.setItem(key + '_expiresIn', schedule);
} catch(e) {
console.log('setStorage: Error setting key ['+ key + '] in localStorage: ' + JSON.stringify(e) );
return false;
}
return true;
}
JPanel testPanel = new JPanel();
testPanel.setLayout(new BoxLayout(testPanel, BoxLayout.Y_AXIS));
/*add variables here and add them to testPanel
e,g`enter code here`
testPanel.add(nameLabel);
testPanel.add(textName);
*/
testPanel.setVisible(true);
You Write Two Function
//When Expression is Number
public static double? isNull(double? Expression, double? Value)
{
if (Expression ==null)
{
return Value;
}
else
{
return Expression;
}
}
//When Expression is string (Can not send Null value in string Expression
public static string isEmpty(string Expression, string Value)
{
if (Expression == "")
{
return Value;
}
else
{
return Expression;
}
}
They Work Very Well
change your code to:
function ChangePurpose(Vid, PurId) {
var Success = false;
$.ajax({
type: "POST",
url: "CHService.asmx/SavePurpose",
dataType: "text",
async: false,
data: JSON.stringify({ Vid: Vid, PurpId: PurId }),
contentType: "application/json; charset=utf-8",
success: function (data) {
Success = true;
},
error: function (textStatus, errorThrown) {
Success = false;
}
});
//done after here
return Success;
}
You can only return the values from a synchronous
function. Otherwise you will have to make a callback
.
So I just added async:false,
to your ajax call
Update:
jquery ajax calls are asynchronous by default. So success & error functions will be called when the ajax load is complete. But your return statement will be executed just after the ajax call is started.
A better approach will be:
// callbackfn is the pointer to any function that needs to be called
function ChangePurpose(Vid, PurId, callbackfn) {
var Success = false;
$.ajax({
type: "POST",
url: "CHService.asmx/SavePurpose",
dataType: "text",
data: JSON.stringify({ Vid: Vid, PurpId: PurId }),
contentType: "application/json; charset=utf-8",
success: function (data) {
callbackfn(data)
},
error: function (textStatus, errorThrown) {
callbackfn("Error getting the data")
}
});
}
function Callback(data)
{
alert(data);
}
and call the ajax as:
// Callback is the callback-function that needs to be called when asynchronous call is complete
ChangePurpose(Vid, PurId, Callback);
Above answer is partially correct for me, but In my scenario, I want to set the value to a state, because I have used the value to show/toggle a modal. So I have used like below. Hope it will help someone.
class Child extends React.Component {
state = {
visible:false
};
handleCancel = (e) => {
e.preventDefault();
this.setState({ visible: false });
};
componentDidMount() {
this.props.onRef(this)
}
componentWillUnmount() {
this.props.onRef(undefined)
}
method() {
this.setState({ visible: true });
}
render() {
return (<Modal title="My title?" visible={this.state.visible} onCancel={this.handleCancel}>
{"Content"}
</Modal>)
}
}
class Parent extends React.Component {
onClick = () => {
this.child.method() // do stuff
}
render() {
return (
<div>
<Child onRef={ref => (this.child = ref)} />
<button onClick={this.onClick}>Child.method()</button>
</div>
);
}
}

just in case someone comes with this question, this is how I do it, please forget about the repository object, I'm using the Repository Pattern, you can use your object context to retrieve the entities. And also don't pay attention to my entity names, my entity type Action has nothing to do with an MVC Action.
Controller:
ViewBag.ActionStatusId = new SelectList(repository.GetAll<ActionStatus>(), "ActionStatusId", "Name", myAction.ActionStatusId);
Pay attention that the last variable of the SelectList constructor is the selected value (object selectedValue)
Then this is my view to render it:
<div class="editor-label">
@Html.LabelFor(model => model.ActionStatusId, "ActionStatus")
</div>
<div class="editor-field">
@Html.DropDownList("ActionStatusId")
@Html.ValidationMessageFor(model => model.ActionStatusId)
</div>
I think it is pretty simple, I hope this helps! :)
A newbie mistake was generating the same error message in my case.
The app-root
tag wasn't present in index.html
You want to use two keys independently, so you have two choices:
Store the data redundantly with two dicts as {'banana' : {'blue' : 4, ...}, .... }
and {'blue': {'banana':4, ...} ...}
. Then, searching and sorting is easy but you have to make sure you modify the dicts together.
Store it just one dict, and then write functions that iterate over them eg.:
d = {'banana' : {'blue' : 4, 'yellow':6}, 'apple':{'red':1} }
blueFruit = [(fruit,d[fruit]['blue']) if d[fruit].has_key('blue') for fruit in d.keys()]
Both facet_wrap
and facet_grid
also accept input from ifelse
as an argument. So if the variable used for faceting is logical, the solution is very simple:
facet_wrap(~ifelse(variable, "Label if true", "Label if false"))
If the variable has more categories, the ifelse
statement needs to be nested.
As a side effect, this also allows the creation of the groups to be faceted within the ggplot
call.
In a Firebird database the AFTER myOtherColumn
does not work but you can try re-positioning the column using:
ALTER TABLE name ALTER column POSITION new_position
I guess it may work in other cases as well.
Try this code. This does what you want.

I just came across this problem and wanted to find something about the performance, but I couldn't, so I wrote a benchmarking script on my own:
% Config:
rows = 1e6;
runs = 50;
% Start:
orig = round(rand(rows, 1));
t1 = 0;
for i = 1:runs
A = orig;
tic
A(A == 0) = [];
t1 = t1 + toc;
end
t1 = t1 / runs;
t2 = 0;
for i = 1:runs
A = orig;
tic
A = A(A ~= 0);
t2 = t2 + toc;
end
t2 = t2 / runs;
t1
t2
t1 / t2
So you see, the solution using A = A(A ~= 0)
is the quicker of the two :)
Below is how I got this working.
The Key point was: I needed to use the ViewModel associated with the view in order for the runtime to be able to resolve the object in the request.
[I know that that there is a way to bind an object other than the default ViewModel object but ended up simply populating the necessary properties for my needs as I could not get it to work]
[HttpPost]
public ActionResult GetDataForInvoiceNumber(MyViewModel myViewModel)
{
var invoiceNumberQueryResult = _viewModelBuilder.HydrateMyViewModelGivenInvoiceDetail(myViewModel.InvoiceNumber, myViewModel.SelectedCompanyCode);
return Json(invoiceNumberQueryResult, JsonRequestBehavior.DenyGet);
}
The JQuery script used to call this action method:
var requestData = {
InvoiceNumber: $.trim(this.value),
SelectedCompanyCode: $.trim($('#SelectedCompanyCode').val())
};
$.ajax({
url: '/en/myController/GetDataForInvoiceNumber',
type: 'POST',
data: JSON.stringify(requestData),
dataType: 'json',
contentType: 'application/json; charset=utf-8',
error: function (xhr) {
alert('Error: ' + xhr.statusText);
},
success: function (result) {
CheckIfInvoiceFound(result);
},
async: true,
processData: false
});
I believe sideshowbarker 's answer here has all the info you need to fix this. If your problem is just No 'Access-Control-Allow-Origin' header is present on the response you're getting, you can set up a CORS proxy to get around this. Way more info on it in the linked answer
The default behaviour is false:
By default, ApplicationContext implementations eagerly create and configure all singleton beans as part of the initialization process. Generally, this pre-instantiation is desirable, because errors in the configuration or surrounding environment are discovered immediately, as opposed to hours or even days later. When this behavior is not desirable, you can prevent pre-instantiation of a singleton bean by marking the bean definition as lazy-initialized. A lazy-initialized bean tells the IoC container to create a bean instance when it is first requested, rather than at startup.
chsh -s $(which zsh)
You'll be prompted for your password, but once you update your settings any new iTerm/Terminal sessions you start on that machine will default to zsh.
You can rename your Conda env by just renaming the env folder. Here is the proof:
You can find your Conda env folder inside of C:\ProgramData\Anaconda3\envs
or you can enter conda env list
to see the list of conda envs and its location.
Highlight the cells, format cells, select Custom then select zero.
There's an article on Code Project about using GDI+ for .NET to do photo resizing using, say, Bicubic interpolation.
There was also another article about this topic on another blog (MS employee, I think), but I can't find the link anywhere. :( Perhaps someone else can find it?
If you want to make it fully automatic, one click, or to load automatically into Excel from say a web page, but can't generate proper Excel files, then I would suggest looking at SYLK format as an alternative. OK it is not as simple as CSV but it is text based and very easy to implement and it supports UTF-8 with no issues.
I wrote a PHP class that receives the data and outputs a SYLK file which will open directly in Excel by just clicking the file (or will auto-launch Excel if you write the file to a web page with the correct mime type. You can even add formatting (like bold, format numbers in particular ways etc) and change column sizes, or auto size columns to the text in the columns and all in all the code is probably not more than about 100 lines.
It is dead easy to reverse engineer SYLK by creating a simple spreadsheet and saving as SYLK and then reading it with a text editor. The first block are headers and standard number formats that you will recognise (which you just regurgitate in every file you create), then the data is simply an X/Y coordinate and a value.
The other solution is attaching the image as attachment and then referencing it html code using cid. HTML Code:
<html>
<head>
</head>
<body>
<img width=100 height=100 id=""1"" src=""cid:Logo.jpg"">
</body>
</html>
C# Code:
EmailMessage email = new EmailMessage(service);
email.Subject = "Email with Image";
email.Body = new MessageBody(BodyType.HTML, html);
email.ToRecipients.Add("[email protected]");
string file = @"C:\Users\acv\Pictures\Logo.jpg";
email.Attachments.AddFileAttachment("Logo.jpg", file);
email.Attachments[0].IsInline = true;
email.Attachments[0].ContentId = "Logo.jpg";
email.SendAndSaveCopy();
In case if you're trying to deploy a project using VSTS, then issue might be connected with checking "Hosted Windows Container" option instead of "Hosted VS2017"(or 18, etc.):
strtotime will convert your date string to a unix time stamp. (seconds since the unix epoch.
$ts1 = strtotime($date1);
$ts2 = strtotime($date2);
$seconds_diff = $ts2 - $ts1;
You will first need to create a custom layout xml which will represent a single item in your list. You will add your two buttons to this layout along with any other items you want to display from your list.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<TextView
android:id="@+id/list_item_string"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_alignParentLeft="true"
android:paddingLeft="8dp"
android:textSize="18sp"
android:textStyle="bold" />
<Button
android:id="@+id/delete_btn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:layout_marginRight="5dp"
android:text="Delete" />
<Button
android:id="@+id/add_btn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toLeftOf="@id/delete_btn"
android:layout_centerVertical="true"
android:layout_marginRight="10dp"
android:text="Add" />
</RelativeLayout>
Next you will need to create a Custom ArrayAdapter Class which you will use to inflate your xml layout, as well as handle your buttons and on click events.
public class MyCustomAdapter extends BaseAdapter implements ListAdapter {
private ArrayList<String> list = new ArrayList<String>();
private Context context;
public MyCustomAdapter(ArrayList<String> list, Context context) {
this.list = list;
this.context = context;
}
@Override
public int getCount() {
return list.size();
}
@Override
public Object getItem(int pos) {
return list.get(pos);
}
@Override
public long getItemId(int pos) {
return list.get(pos).getId();
//just return 0 if your list items do not have an Id variable.
}
@Override
public View getView(final int position, View convertView, ViewGroup parent) {
View view = convertView;
if (view == null) {
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
view = inflater.inflate(R.layout.my_custom_list_layout, null);
}
//Handle TextView and display string from your list
TextView listItemText = (TextView)view.findViewById(R.id.list_item_string);
listItemText.setText(list.get(position));
//Handle buttons and add onClickListeners
Button deleteBtn = (Button)view.findViewById(R.id.delete_btn);
Button addBtn = (Button)view.findViewById(R.id.add_btn);
deleteBtn.setOnClickListener(new View.OnClickListener(){
@Override
public void onClick(View v) {
//do something
list.remove(position); //or some other task
notifyDataSetChanged();
}
});
addBtn.setOnClickListener(new View.OnClickListener(){
@Override
public void onClick(View v) {
//do something
notifyDataSetChanged();
}
});
return view;
}
}
Finally, in your activity you can instantiate your custom ArrayAdapter class and set it to your listview.
public class MyActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_my_activity);
//generate list
ArrayList<String> list = new ArrayList<String>();
list.add("item1");
list.add("item2");
//instantiate custom adapter
MyCustomAdapter adapter = new MyCustomAdapter(list, this);
//handle listview and assign adapter
ListView lView = (ListView)findViewById(R.id.my_listview);
lView.setAdapter(adapter);
}
Hope this helps!
You probably want to read in more numbers, not only one. For this, you need a loop
int main()
{
int input = 0;
while(input != -1){
vector<int> V;
cout << "Enter your numbers to be evaluated: " << endl;
cin >> input;
V.push_back(input);
write_vector(V);
}
return 0;
}
Note, with this version, it is not possible to add the number -1 as it is the "end signal". Type numbers as long as you like, it will be aborted when you type -1.

svn: The repository at 'svn://repourl/reponame/foldername' has uuid 'm/reponame', but the WC has 'b5b39681-0ff6-784b-ad26-2846b9ea8e7d'
Every subversion repo has a unique identifier (uuid). Subversion uses this to make sure that the repo is actually the same when doing things like switching. You should probably change the uuid on the server to be the same as before.
download rpm packages and run the following command:
rpm -Uvh glibc-2.15-60.el6.x86_64.rpm \
glibc-common-2.15-60.el6.x86_64.rpm \
glibc-devel-2.15-60.el6.x86_64.rpm \
glibc-headers-2.15-60.el6.x86_64.rpm
You can use context
syntax with this
or $(this)
. This is the same effect as find()
.
$('select').change(function() {_x000D_
console.log('Clicked option value => ' + $(this).val());_x000D_
<!-- undefined console.log('$(this) without explicit :select => ' + $(this).data('id')); -->_x000D_
<!-- error console.log('this without explicit :select => ' + this.data('id')); -->_x000D_
console.log(':select & $(this) => ' + $(':selected', $(this)).data('id'));_x000D_
console.log(':select & this => ' + $(':selected', this).data('id'));_x000D_
console.log('option:select & this => ' + $('option:selected', this).data('id'));_x000D_
console.log('$(this) & find => ' + $(this).find(':selected').data('id'));_x000D_
});
_x000D_
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<select>_x000D_
<option data-id="1">one</option>_x000D_
<option data-id="2">two</option>_x000D_
<option data-id="3">three</option>_x000D_
</select>
_x000D_
As a matter of microoptimization, you might opt for find()
. If you are more of a code golfer, the context syntax is more brief. It comes down to coding style basically.
Here is a relevant performance comparison.
ISO 8601 (MSDN datetime formats)
Console.WriteLine(DateTime.UtcNow.ToString("s") + "Z");
2009-11-13T10:39:35Z
The Z is there because
If the time is in UTC, add a 'Z' directly after the time without a space. 'Z' is the zone designator for the zero UTC offset. "09:30 UTC" is therefore represented as "09:30Z" or "0930Z". "14:45:15 UTC" would be "14:45:15Z" or "144515Z".
int hours = TimeZoneInfo.Local.BaseUtcOffset.Hours;
string offset = string.Format("{0}{1}",((hours >0)? "+" :""),hours.ToString("00"));
string isoformat = DateTime.Now.ToString("s") + offset;
Console.WriteLine(isoformat);
Two things to note: + or - is needed after the time but obviously + doesn't show on positive numbers. According to wikipedia the offset can be in +hh format or +hh:mm. I've kept to just hours.
As far as I know, RFC1123 (HTTP date, the "u" formatter) isn't meant to give time zone offsets. All times are intended to be GMT/UTC.

I recommend avoiding git reset
when possible -- especially for Git-novices. Unless you really need to automate a process based on a number of commits, there is a less exotic way...
git merge --squash (working branch name)
git commit
The commit message will be prepopulated based on the squash.
I'm having the same issue here and I was a bit afraid of checking the last box, since I have no idea what the 3rd party SDK will do with the data collected and if they will respect the Limit Ad Settings.
But I found a post by a Google Admob programmer, Eric Leichtenschlag, on their forums:
The Google Mobile Ads SDK and the Google Conversion Tracking SDK utilize Apple's advertising identifier introduced in iOS 6 (IDFA). While each developer is responsible for how they access device data, the SDKs use IDFA under the guidelines laid out in the iOS developer program license agreement, including Limit Ad Tracking.
Including Limit Ad Tracking. This is what the last box is all about. So you must check the that box if you use AdMob. If you use other SDK I strongly recommend checking if they respect the guidelines as well.
Since I run only ads (Google AdMob), I checked the first (Serve ads...) and last box (I, ___, confirm...). App was approved and released, no issues.

Using generics (as in the above answers) is your best bet here. I've just double checked and:
test.put("test", arraylistone);
ArrayList current = new ArrayList();
current = (ArrayList) test.get("test");
will work as well, through I wouldn't recommend it as the generics ensure that only the correct data is added, rather than trying to do the handling at retrieval time.
Besides changing it to Console (/SUBSYSTEM:CONSOLE)
as others have said, you may need to change the entry point in Properties -> Linker -> Advanced -> Entry Point. Set it to mainCRTStartup.
It seems that Visual Studio might be searching for the WinMain function instead of main, if you don't specify otherwise.
In my case, I couldn't see any of the controls in the project. Only when right clicking on toolBox and selecting "Show All" I saw them, but yet they were disabled...
Changing Project type from Windows application to ClassLibrary made the fix.
Update: for connecting to another sql server and executing sql statements, you have to use sqlcmd Utility. This is typically done in a batch file. You can combine this with xmp_cmdshell if you want to execute it within management studio.
one way is to configure a linked server. then you can append the linked server and the database name to the table name. (select * from linkedserver.database.dbo.TableName)

To anyone seeing this later on, as it currently (Aug. 2017) tops google: It is worth mentioning, that this behavior will be altered in Rails 5.2, and has deprecation warnings as of Rails 5.1, as ActiveModel::Dirty changed a bit.
What do I change?
If you're using attribute_changed?
method in the after_*
-callbacks, you'll see a warning like:
DEPRECATION WARNING: The behavior of
attribute_changed?
inside of after callbacks will be changing in the next version of Rails. The new return value will reflect the behavior of calling the method aftersave
returned (e.g. the opposite of what it returns now). To maintain the current behavior, usesaved_change_to_attribute?
instead. (called from some_callback at /PATH_TO/app/models/user.rb:15)
As it mentions, you could fix this easily by replacing the function with saved_change_to_attribute?
. So for example, name_changed?
becomes saved_change_to_name?
.
Likewise, if you're using the attribute_change
to get the before-after values, this changes as well and throws the following:
DEPRECATION WARNING: The behavior of
attribute_change
inside of after callbacks will be changing in the next version of Rails. The new return value will reflect the behavior of calling the method aftersave
returned (e.g. the opposite of what it returns now). To maintain the current behavior, usesaved_change_to_attribute
instead. (called from some_callback at /PATH_TO/app/models/user.rb:20)
Again, as it mentions, the method changes name to saved_change_to_attribute
which returns ["old", "new"]
.
or use saved_changes
, which returns all the changes, and these can be accessed as saved_changes['attribute']
.
Use your browser's network inspector (F12) to see when the browser is requesting the bgbody.png image and what absolute path it's using and why the server is returning a 404 response.
...assuming that bgbody.png actually exists :)
Is your CSS in a stylesheet file or in a <style>
block in a page? If it's in a stylesheet then the relative path must be relative to the CSS stylesheet (not the document that references it). If it's in a page then it must be relative to the current resource path. If you're using non-filesystem-based resource paths (i.e. using URL rewriting or URL routing) then this will cause problems and it's best to always use absolute paths.
Going by your relative path it looks like you store your images separately from your stylesheets. I don't think this is a good idea - I support storing images and other resources, like fonts, in the same directory as the stylesheet itself, as it simplifies paths and is also a more logical filesystem arrangement.
rand() will return numbers between 0 and RAND_MAX, which is at least 32767.
If you want to get a number within a range, you can just use modulo.
int value = rand() % 66; // 0-65
For more accuracy, check out this article. It discusses why modulo is not necessarily good (bad distributions, particularly on the high end), and provides various options.
Using current browsers you can use it like this:
img {
-webkit-filter: grayscale(100%); /* Chrome, Safari, Opera */
filter: grayscale(100%);
}
and to remedy it:
img:hover{
-webkit-filter: grayscale(0%); /* Chrome, Safari, Opera */
filter: grayscale(0%);
}
worked with me and is much shorter. There is even more one can do within the CSS:
filter: none | blur() | brightness() | contrast() | drop-shadow() | grayscale() |
hue-rotate() | invert() | opacity() | saturate() | sepia() | url();
For more information and supporting browsers see this: http://www.w3schools.com/cssref/css3_pr_filter.asp
It seems that IDLE changes its current working dir to location of the script that is executed, while when running the script using cmd doesn't do that and it leaves CWD as it is.
To change current working dir to the one containing your script you can use:
import os
os.chdir(os.path.dirname(__file__))
print(os.getcwd())
The __file__
variable is available only if you execute script from file, and it contains path to the file. More on it here: Python __file__ attribute absolute or relative?
Use DateTime with DateTime::format()
$datetime = new DateTime($dateTimeString);
echo $datetime->format('w');
It depends on the Test Construct around the operator. Your options are double parentheses, double brackets, single brackets, or test
.
If you use ((
…))
, you are testing arithmetic equality with ==
as in C:
$ (( 1==1 )); echo $?
0
$ (( 1==2 )); echo $?
1
(Note: 0
means true
in the Unix sense and a failed test results in a non-zero number.)
Using -eq
inside of double parentheses is a syntax error.
If you are using [
…]
(or single brackets) or [[
…]]
(or double brackets), or test
you can use one of -eq
, -ne
, -lt
, -le
, -gt
, or -ge
as an arithmetic comparison.
$ [ 1 -eq 1 ]; echo $?
0
$ [ 1 -eq 2 ]; echo $?
1
$ test 1 -eq 1; echo $?
0
The ==
inside of single or double brackets (or the test
command) is one of the string comparison operators:
$ [[ "abc" == "abc" ]]; echo $?
0
$ [[ "abc" == "ABC" ]]; echo $?
1
As a string operator, =
is equivalent to ==
. Also, note the whitespace around =
or ==
: it’s required.
While you can do [[ 1 == 1 ]]
or [[ $(( 1+1 )) == 2 ]]
it is testing the string equality — not the arithmetic equality.
So -eq
produces the result probably expected that the integer value of 1+1
is equal to 2
even though the right-hand side is a string and has a trailing space:
$ [[ $(( 1+1 )) -eq "2 " ]]; echo $?
0
While a string comparison of the same picks up the trailing space and therefore the string comparison fails:
$ [[ $(( 1+1 )) == "2 " ]]; echo $?
1
And a mistaken string comparison can produce a completely wrong answer. 10
is lexicographically less than 2
, so a string comparison returns true
or 0
. So many are bitten by this bug:
$ [[ 10 < 2 ]]; echo $?
0
The correct test for 10
being arithmetically less than 2
is this:
$ [[ 10 -lt 2 ]]; echo $?
1
In comments, there is a question about the technical reason why using the integer -eq
on strings returns true for strings that are not the same:
$ [[ "yes" -eq "no" ]]; echo $?
0
The reason is that Bash is untyped. The -eq
causes the strings to be interpreted as integers if possible including base conversion:
$ [[ "0x10" -eq 16 ]]; echo $?
0
$ [[ "010" -eq 8 ]]; echo $?
0
$ [[ "100" -eq 100 ]]; echo $?
0
And 0
if Bash thinks it is just a string:
$ [[ "yes" -eq 0 ]]; echo $?
0
$ [[ "yes" -eq 1 ]]; echo $?
1
So [[ "yes" -eq "no" ]]
is equivalent to [[ 0 -eq 0 ]]
Last note: Many of the Bash specific extensions to the Test Constructs are not POSIX and therefore may fail in other shells. Other shells generally do not support [[...]]
and ((...))
or ==
.

For anyone looking to completely remove the soft-nav on a rooted (or custom ROM) android device, you can modify the build.prop
text file within the system folder.
Set the following variable/value:
gemu.hw.mainkeys=1
This is what vendors use to disable the soft nav, when they have physical buttons.
# mysqladmin -u root -p status
Output:
Enter password:
Uptime: 4 Threads: 1 Questions: 62 Slow queries: 0 Opens: 51 Flush tables: 1 Open tables: 45 Queries per second avg: 15.500
It means MySQL serer is running
If server is not running then it will dump error as follows
# mysqladmin -u root -p status
Output :
mysqladmin: connect to server at 'localhost' failed
error: 'Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)'
Check that mysqld is running and that the socket: '/var/run/mysqld/mysqld.sock' exists!
So Under Debian Linux you can type following command
# /etc/init.d/mysql status
Try this way. This worked me.
wget nodejs.org/dist/v0.10.36/node-v0.10.36-linux-x64.tar.gz(download file)
Go to the directory where the Node.js binary was downloaded to, and then run command i.e, sudo tar -C /usr/local --strip-components 1 -xzf node-v0.10.36-linux-x64.tar.gz to install the Node.js binary package in “/usr/local/”.
You can check:-
$ node -v
v0.10.36
$ npm -v
1.4.28
Rather simpler method would be by using JavaScript method of innerHTML.
document.getElementById("#id_goes_here").innerHTML = "";
Rather simpler and more effective way.
I think these could be helpful for you .
Using a SELECT
statement with a simple CASE
expression
Within a SELECT
statement, a simple CASE
expression allows for only an equality check; no other comparisons are made. The following example uses the CASE
expression to change the display of product line categories to make them more understandable.
USE AdventureWorks2012;
GO
SELECT ProductNumber, Category =
CASE ProductLine
WHEN 'R' THEN 'Road'
WHEN 'M' THEN 'Mountain'
WHEN 'T' THEN 'Touring'
WHEN 'S' THEN 'Other sale items'
ELSE 'Not for sale'
END,
Name
FROM Production.Product
ORDER BY ProductNumber;
GO
Using a SELECT
statement with a searched CASE
expression
Within a SELECT
statement, the searched CASE
expression allows for values to be replaced in the result set based on comparison values. The following example displays the list price as a text comment based on the price range for a product.
USE AdventureWorks2012;
GO
SELECT ProductNumber, Name, "Price Range" =
CASE
WHEN ListPrice = 0 THEN 'Mfg item - not for resale'
WHEN ListPrice < 50 THEN 'Under $50'
WHEN ListPrice >= 50 and ListPrice < 250 THEN 'Under $250'
WHEN ListPrice >= 250 and ListPrice < 1000 THEN 'Under $1000'
ELSE 'Over $1000'
END
FROM Production.Product
ORDER BY ProductNumber ;
GO
Using CASE
in an ORDER BY
clause
The following examples uses the CASE
expression in an ORDER BY
clause to determine the sort order of the rows based on a given column value. In the first example, the value in the SalariedFlag column of the HumanResources.Employee table is evaluated. Employees that have the SalariedFlag set to 1 are returned in order by the BusinessEntityID in descending order. Employees that have the SalariedFlag set to 0 are returned in order by the BusinessEntityID in ascending order. In the second example, the result set is ordered by the column TerritoryName when the column CountryRegionName is equal to 'United States' and by CountryRegionName for all other rows.
SELECT BusinessEntityID, SalariedFlag
FROM HumanResources.Employee
ORDER BY CASE SalariedFlag WHEN 1 THEN BusinessEntityID END DESC
,CASE WHEN SalariedFlag = 0 THEN BusinessEntityID END;
GO
SELECT BusinessEntityID, LastName, TerritoryName, CountryRegionName
FROM Sales.vSalesPerson
WHERE TerritoryName IS NOT NULL
ORDER BY CASE CountryRegionName WHEN 'United States' THEN TerritoryName
ELSE CountryRegionName END;
Using CASE
in an UPDATE
statement
The following example uses the CASE
expression in an UPDATE
statement to determine the value that is set for the column VacationHours for employees with SalariedFlag set to 0. When subtracting 10 hours from VacationHours results in a negative value, VacationHours is increased by 40 hours; otherwise, VacationHours is increased by 20 hours. The OUTPUT
clause is used to display the before and after vacation values.
USE AdventureWorks2012;
GO
UPDATE HumanResources.Employee
SET VacationHours =
( CASE
WHEN ((VacationHours - 10.00) < 0) THEN VacationHours + 40
ELSE (VacationHours + 20.00)
END
)
OUTPUT Deleted.BusinessEntityID, Deleted.VacationHours AS BeforeValue,
Inserted.VacationHours AS AfterValue
WHERE SalariedFlag = 0;
Using CASE
in a HAVING
clause
The following example uses the CASE
expression in a HAVING
clause to restrict the rows returned by the SELECT
statement. The statement returns the the maximum hourly rate for each job title in the HumanResources.Employee table. The HAVING
clause restricts the titles to those that are held by men with a maximum pay rate greater than 40 dollars or women with a maximum pay rate greater than 42 dollars.
USE AdventureWorks2012;
GO
SELECT JobTitle, MAX(ph1.Rate)AS MaximumRate

JOIN HumanResources.EmployeePayHistory AS ph1 ON e.BusinessEntityID = ph1.BusinessEntityID
GROUP BY JobTitle
HAVING (MAX(CASE WHEN Gender = 'M'
THEN ph1.Rate
ELSE NULL END) > 40.00
OR MAX(CASE WHEN Gender = 'F'
THEN ph1.Rate
ELSE NULL END) > 42.00)
ORDER BY MaximumRate DESC;

Since we're already using JQuery, we can let page designers add custom messages to the markup rather than the code:
<input ... data-msg-required="my message" ...
Or, a more general solution using a single short data-msg attribute on all fields:
<form id="form1">
<input type="text" id="firstName" name="firstName"
data-msg="Please enter your first name" />
<br />
<input type="text" id="lastName" name="lastName"
data-msg="Please enter your last name" />
<br />
<input type="submit" />
</form>
And the code then contains something like this:
function getMsg(selector) {
return $(selector).attr('data-msg');
}
$('#form1').validate({
// ...
messages: {
firstName: getMsg('#firstName'),
lastName: getMsg('#lastName')
}
// ...
});
You can't inject content from another site (domain) using AJAX. The reason an iFrame is suited for these kinds of things is that you can specify the source to be from another domain.
The documentation has been updated. My answer has substantial changes vs the accepted answer: I wanted to reflect documentation is up-to-date, and accepted answer has a few broken links.
Also, I didn't understand when the accepted answer said "it defaults to node server.js
". I think the documentation clarifies the default behavior:
npm-start
Start a package
Synopsis
npm start [-- <args>]
Description
This runs an arbitrary command specified in the package's "
start
" property of its "scripts
" object. If no "start
" property is specified on the "scripts
" object, it will runnode server.js
.
In summary, running npm start
could do one of two things:
npm start {command_name}
: Run an arbitrary command (i.e. if such command is specified in the start
property of package.json's scripts
object)npm start
: Else if no start
property exists (or no command_name
is passed): Run node server.js
, (which may not be appropriate, for example the OP doesn't have server.js
; the OP runs node
app.js
)package.json
in the directory where you run npm start
, you may see an error: npm ERR! enoent ENOENT: no such file or directory, open '.\package.json'
Here's a possible solution:
public class NumInput {
public static void main(String [] args) {
int min = Integer.MAX_VALUE;
int max = Integer.MIN_VALUE;
Scanner s = new Scanner(System.in);
while (true) {
System.out.print("Enter a Value: ");
int val = s.nextInt();
if (val == 0) {
break;
}
if (val < min) {
min = val;
}
if (val > max) {
max = val;
}
}
System.out.println("min: " + min);
System.out.println("max: " + max);
}
}
(not sure about using int or double thought)

A sensible approach to scaling Docker could be:
Another docker open sourced project from Yandex:
The actual answer to this (reduce) problem is: Just use a loop!
initial_value = 0
for x in the_list:
initial_value += x #or any function.
This will be faster than a reduce and things like PyPy can optimize loops like that.
BTW, the sum case should be solved with the sum
function
There is a very fundamental difference between the two. In case of Singleton design pattern, only one instance of a class will be created per classLoader while that is not the case with Spring singleton as in the later one shared bean instance for the given id per IoC container is created.
For example, if I have a class with the name "SpringTest" and my XML file looks something like this :-
<bean id="test1" class="com.SpringTest" scope="singleton">
--some properties here
</bean>
<bean id="test2" class="com.SpringTest" scope="singleton">
--some properties here
</bean>
So now in the main class if you will check the reference of the above two it will return false as according to Spring documentation:-
When a bean is a singleton, only one shared instance of the bean will be managed, and all requests for beans with an id or ids matching that bean definition will result in that one specific bean instance being returned by the Spring container
So as in our case, the classes are the same but the id's that we have provided are different hence resulting in two different instances being created.
First make sure the required number is a valid index for the string from beginning or end , then you can simply use array subscript notation.
use len(s)
to get string length

A very crude analogy: if we compare git commit
to saving an edited file, then git push
would be copying that file to another location.
Please don't take this analogy out of this context -- committing and pushing are not quite like saving an edited file and copying it. That said, it should hold for comparisons sake.
When a
and b
are 1-dimensional sequences, numpy.cov(a,b)[0][1]
is equivalent to your cov(a,b)
.
The 2x2 array returned by np.cov(a,b)
has elements equal to
cov(a,a) cov(a,b)
cov(a,b) cov(b,b)
(where, again, cov
is the function you defined above.)
I think you missed a key point in the documentation for .add()
Mutates the original moment by adding time.
You appear to be treating it as a function that returns the immutable result. Easy mistake to make. :)
If you use the return value, it is the same actual object as the one you started with. It's just returned as a convenience for method chaining.
You can work around this behavior by cloning the moment, as described here.
Also, you cannot just use ==
to test. You could format each moment to the same output and compare those, or you could just use the .isSame()
method.
Your code is now:
var timestring1 = "2013-05-09T00:00:00Z";
var timestring2 = "2013-05-09T02:00:00Z";
var startdate = moment(timestring1);
var expected_enddate = moment(timestring2);
var returned_endate = moment(startdate).add(2, 'hours'); // see the cloning?
returned_endate.isSame(expected_enddate) // true
For an alternative cryptography library, have a look at Bouncy Castle. It has AES and a lot of added functionality. It's a liberal open source library. You will have to use the lightweight, proprietary Bouncy Castle API for this to work though.
use DateTime.ParseExact
string strDate = "24/01/2013";

DateTime date = DateTime.ParseExact(strDate, "dd/MM/YYYY", CultureInfo.InvariantCulture)

MS SQL Server 2008 introduces the MERGE statement, which I believe is part of the SQL:2003 standard. As many have shown it is not a big deal to handle one row cases, but when dealing with large datasets, one needs a cursor, with all the performance problems that come along. The MERGE statement will be much welcomed addition when dealing with large datasets.
Becasue is a TextBox already initialized would be better to control if there is something in there outside the empty string (which is no null or empty string I am afraid). What I did is just check is there is something different than "", if so do the thing:
if (TextBox.Text != "") //Something different than ""?
{
//Do your stuff
}
else
{
//Do NOT do your stuff
}
I'm the author of Docker.
The short answer is that if you want to manage machines, you should use Vagrant. And if you want to build and run applications environments, you should use Docker.
Vagrant is a tool for managing virtual machines. Docker is a tool for building and deploying applications by packaging them into lightweight containers. A container can hold pretty much any software component along with its dependencies (executables, libraries, configuration files, etc.), and execute it in a guaranteed and repeatable runtime environment. This makes it very easy to build your app once and deploy it anywhere - on your laptop for testing, then on different servers for live deployment, etc.
It's a common misconception that you can only use Docker on Linux. That's incorrect; you can also install Docker on Mac, and Windows. When installed on Mac, Docker bundles a tiny Linux VM (25 MB on disk!) which acts as a wrapper for your container. Once installed this is completely transparent; you can use the Docker command-line in exactly the same way. This gives you the best of both worlds: you can test and develop your application using containers, which are very lightweight, easy to test and easy to move around (see for example https://hub.docker.com for sharing reusable containers with the Docker community), and you don't need to worry about the nitty-gritty details of managing virtual machines, which are just a means to an end anyway.
In theory it's possible to use Vagrant as an abstraction layer for Docker. I recommend against this for two reasons:
First, Vagrant is not a good abstraction for Docker. Vagrant was designed to manage virtual machines. Docker was designed to manage an application runtime. This means that Docker, by design, can interact with an application in richer ways, and has more information about the application runtime. The primitives in Docker are processes, log streams, environment variables, and network links between components. The primitives in Vagrant are machines, block devices, and ssh keys. Vagrant simply sits lower in the stack, and the only way it can interact with a container is by pretending it's just another kind of machine, that you can "boot" and "log into". So, sure, you can type "vagrant up" with a Docker plugin and something pretty will happen. Is it a substitute for the full breadth of what Docker can do? Try native Docker for a couple days and see for yourself :)
Second, the lock-in argument. "If you use Vagrant as an abstraction, you will not be locked into Docker!". From the point of view of Vagrant, which is designed to manage machines, this makes perfect sense: aren't containers just another kind of machine? Just like Amazon EC2 and VMware, we must be careful not to tie our provisioning tools to any particular vendor! This would create lock-in - better to abstract it all away with Vagrant. Except this misses the point of Docker entirely. Docker doesn't provision machines; it wraps your application in a lightweight portable runtime which can be dropped anywhere.
What runtime you choose for your application has nothing to do with how you provision your machines! For example it's pretty frequent to deploy applications to machines which are provisioned by someone else (for example an EC2 instance deployed by your system administrator, perhaps using Vagrant), or to bare metal machines which Vagrant can't provision at all. Conversely, you may use Vagrant to provision machines which have nothing to do with developing your application - for example a ready-to-use Windows IIS box or something. Or you may use Vagrant to provision machines for projects which don't use Docker - perhaps they use a combination of rubygems and rvm for dependency management and sandboxing for example.
In summary: Vagrant is for managing machines, and Docker is for building and running application environments.
Previous answers were insufficient in my case, probably because I'm on Debian 8, while they were referred to some previous distribution.
On Debian 8 modify the service script normally place in /usr/lib/systemd/system/elasticsearch.service
, and add Environment=ES_HEAP_SIZE=8G
just below the other "Environment=*" lines.
Now reload the service script with systemctl daemon-reload
and restart the service. The job should be done!
It's because your '/new_sandbox/'
begins with a /
and thus is assumed to be relative to the root directory. Remove the leading /
.
<table border="1" cellspacing="0" cellpadding= "20">
<tr>
<td id="id1" ></td>
</tr>
</table>
<script>
document.getElementById('id1').style.backgroundColor='#003F87';
</script>
Put id for cell and then change background of the cell.
Try this more succinct code:
Sub LoopOverEachColumn()
Dim WS As Worksheet
For Each WS In ThisWorkbook.Worksheets
ResizeColumns WS
Next WS
End Sub
Private Sub ResizeColumns(WS As Worksheet)
Dim StrSize As String
Dim ColIter As Long
StrSize = "20.14;9.71;35.86;30.57;23.57;21.43;18.43;23.86;27.43;36.71;30.29;31.14;31;41.14;33.86"
For ColIter = 1 To 15
WS.Columns(ColIter).ColumnWidth = Split(StrSize, ";")(ColIter - 1)
Next ColIter
End Sub
If you want additional columns, just change 1 to 15
to 1 to X
where X
is the column index of the column you want, and append the column size you want to StrSize
.
For example, if you want P:P
to have a width of 25
, just add ;25
to StrSize
and change ColIter...
to ColIter = 1 to 16
.
Hope this helps.
Simply & Easy : JavaScript code :
function JoinedOrNot(){
var cat = document.getElementById("mySelect");
if(cat.value == "yes"){
document.getElementById("mySelect1").disabled = false;
}else{
document.getElementById("mySelect1").disabled = true;
}
}
just add in this line [onChange="JoinedOrNot()"] : <select id="mySelect" onchange="JoinedOrNot()">
it's work fine ;)
Click the line number, and then copy and paste the link from the address bar. To select a range, click the number, and then shift click the later number.
Alternatively, the links are a relatively simple format, just append #L<number>
to the end for that specific line number, using the link to the file. Here's a link to the third line of the git
repository's README
:
In most answers it is recommended to fill
the array because otherwise "you can't iterate over it", but this is not true. You can iterate an empty array, just not with forEach
. While loops, for of loops and for i loops work fine.
const count = Array(5);
Does not work.
console.log('---for each loop:---');
count.forEach((empty, index) => {
console.log(`counting ${index}`);
});
These work:
console.log('---for of loop:---');
for (let [index, empty] of count.entries()) {
console.log(`counting for of loop ${index}`);
}
console.log('---for i loop:---');
for (let i = 0, il = count.length; i < il; ++i) {
console.log(`counting for i loop ${i}`);
}
console.log('---while loop:---');
let index = 0;
while (index < count.length) {
console.log(`counting while loop ${index}`);
index++;
}
Check this fiddle with the above examples.
Also angulars *ngFor
works fine with an empty array:
<li *ngFor="let empty of count; let i = index" [ngClass]="
<span>Counting with *ngFor {{i}}</span>
</li>
This little code worked for me, using virtual hosts

Here's my quick and dirty version, basically its splitting up the URL parameters separated by '&' into array elements, and then iterates over that array adding key/value pairs separated by '=' into an object. I'm using decodeURIComponent() to translate the encoded characters to their normal string equivalents (so %20 becomes a space, %26 becomes '&', etc):
function deparam(paramStr) {
let paramArr = paramStr.split('&');
let paramObj = {};
paramArr.forEach(e=>{
let param = e.split('=');
paramObj[param[0]] = decodeURIComponent(param[1]);
});
return paramObj;
}
example:
deparam('abc=foo&def=%5Basf%5D&xyz=5')
returns
{
abc: "foo"
def:"[asf]"
xyz :"5"
}
The only issue is that xyz is a string and not a number (due to using decodeURIComponent()), but beyond that its not a bad starting point.
My personal experience is that shortcuts.xml is overwritten with the initially loaded + later recorded macros and settings when Notepad++ exits. So you can't use Notepad++ itself for editing this file.
Close Notepad++, edit shortcuts.xml by another tool, save it and restart Notepad++.
If you want to access both the key and value, use the following:
Python 2:
for key, value in my_dict.iteritems():
print(key, value)
Python 3:
for key, value in my_dict.items():
print(key, value)
An orthodox way to achieve it, is by defining a new function:
public static String join(String joinStr, String... strings) {
if (strings == null || strings.length == 0) {
return "";
} else if (strings.length == 1) {
return strings[0];
} else {
StringBuilder sb = new StringBuilder(strings.length * 1 + strings[0].length());
sb.append(strings[0]);
for (int i = 1; i < strings.length; i++) {
sb.append(joinStr).append(strings[i]);
}
return sb.toString();
}
}
Sample:
String[] array = new String[] { "7, 7, 7", "Bill", "Bob", "Steve",
"[Bill]", "1,2,3", "Apple ][","~,~" };
String joined;
joined = join(" and ","7, 7, 7", "Bill", "Bob", "Steve", "[Bill]", "1,2,3", "Apple ][","~,~");
joined = join(" and ", array); // same result
System.out.println(joined);
Output:
7, 7, 7 and Bill and Bob and Steve and [Bill] and 1,2,3 and Apple ][ and ~,~
Use align-items: flex-start
on the container, or align-self: flex-start
on the flex items.
No need for display: inline-flex
.
An initial setting of a flex container is align-items: stretch
. This means that flex items will expand to cover the full length of the container along the cross axis.
The align-self
property does the same thing as align-items
, except that align-self
applies to flex items while align-items
applies to the flex container.
By default, align-self
inherits the value of align-items
.
Since your container is flex-direction: column
, the cross axis is horizontal, and align-items: stretch
is expanding the child element's width as much as it can.
You can override the default with align-items: flex-start
on the container (which is inherited by all flex items) or align-self: flex-start
on the item (which is confined to the single item).
Learn more about flex alignment along the cross axis here:

A semaphore is a signaling mechanism used to coordinate between threads. Example: One thread is downloading files from the internet and another thread is analyzing the files. This is a classic producer/consumer scenario. The producer calls signal()
on the semaphore when a file is downloaded. The consumer calls wait()
on the same semaphore in order to be blocked until the signal indicates a file is ready. If the semaphore is already signaled when the consumer calls wait, the call does not block. Multiple threads can wait on a semaphore, but each signal will only unblock a single thread.
A counting semaphore keeps track of the number of signals. E.g. if the producer signals three times in a row, wait()
can be called three times without blocking. A binary semaphore does not count but just have the "waiting" and "signalled" states.
A mutex (mutual exclusion lock) is a lock which is owned by a single thread. Only the thread which have acquired the lock can realease it again. Other threads which try to acquire the lock will be blocked until the current owner thread releases it. A mutex lock does not in itself lock anything - it is really just a flag. But code can check for ownership of a mutex lock to ensure that only one thread at a time can access some object or resource.
A monitor is a higher-level construct which uses an underlying mutex lock to ensure thread-safe access to some object. Unfortunately the word "monitor" is used in a few different meanings depending on context and platform and context, but in Java for example, a monitor is a mutex lock which is implicitly associated with an object, and which can be invoked with the synchronized
keyword. The synchronized
keyword can be applied to a class, method or block and ensures only one thread can execute the code at a time.
The following works for me in Gradle / Groovy for build.gradle
for an Android project, without having to import groovy.io.FileType

FileCollection proGuardFileCollection = files { file('./proguard').listFiles() }
proGuardFileCollection.each {
println "Proguard file located and processed: " + it
}

This can be also thought of as a simple map reduce operation if you would like to think of it from a functional programming perspective.
import os
folders = [("home",".vim"),("home","zathura")]
[reduce(lambda x,y: os.path.join(x,y), each, "") for each in folders]
reduce
is builtin in Python 2.x. In Python 3.x it has been moved to itertools
However the accepted the answer is better.
This has been answered below but answering if you have a list of items that needs to be joined.
String s = "java is an object oriented programming language.";
final StringBuilder result = new StringBuilder(s.length());

for (int i = 0; i < words.length; i++)
{
if (i > 0){
result.append(" ");
}
result.append(Character.toUpperCase(words[i].charAt(0))).append(
words[i].substring(1));
}
System.out.println(result);
Output: Java Is An Object Oriented Programming Language.

if you want to use aggregation functions.
SELECT title, MIN(date)

Dim value As Object = DataGridView1.Rows(e.RowIndex).Cells(e.ColumnIndex).Value
If IsDBNull(value) Then

Using to_char:
select to_char(sysdate, 'YYYY') from dual;
In your example you can use something like:
BETWEEN trunc(sysdate, 'YEAR')
AND add_months(trunc(sysdate, 'YEAR'), 12)-1/24/60/60;
The comparison values are exactly what you request:
select trunc(sysdate, 'YEAR') begin_year
, add_months(trunc(sysdate, 'YEAR'), 12)-1/24/60/60 last_second_year
from dual;
BEGIN_YEAR LAST_SECOND_YEAR

You just need the $('button').prop('disabled', true);
part, the button will automatically take the disabled class.
Adding to the selected answer (as I haven't enough rep to add comment), one way to see the list of available versions (from ref) try:
$ rbenv install -l
For my case, my original Android SDK Build-tools
version is 24 and Andoid SDK Tools
version is 25.1.7. I install Android SDK Build-tools version 23.0.3
by Andoird SDK manager.
Modify these 2 lines to:
buildToolsVersion "23.0.3"
compileSdkVersion 24
Then it works!
from threading import Timer
def TaskManager():
#do stuff
t = Timer( 1, TaskManager )
t.start()
TaskManager()
Here is small sample, it will help beter understanding how it runs. function taskManager() at the end create delayed function call to it self.
Try to change "dalay" variable and you will able to see difference
from threading import Timer, _sleep
# ------------------------------------------
DATA = []
dalay = 0.25 # sec
counter = 0
allow_run = True
FIFO = True
def taskManager():
global counter, DATA, delay, allow_run
counter += 1
if len(DATA) > 0:
if FIFO:
print("["+str(counter)+"] new data: ["+str(DATA.pop(0))+"]")
else:
print("["+str(counter)+"] new data: ["+str(DATA.pop())+"]")
else:
print("["+str(counter)+"] no data")
if allow_run:
#delayed method/function call to it self
t = Timer( dalay, taskManager )
t.start()
else:
print(" END task-manager: disabled")
# ------------------------------------------
def main():
DATA.append("data from main(): 0")
_sleep(2)
DATA.append("data from main(): 1")
_sleep(2)
# ------------------------------------------
print(" START task-manager:")
taskManager()
_sleep(2)
DATA.append("first data")
_sleep(2)
DATA.append("second data")
print(" START main():")
main()
print(" END main():")
_sleep(2)
DATA.append("last data")
allow_run = False
if ( $("#anid").length ) {
alert("element(s) found")
}
else {
alert("nothing found")
}
On the ASP.NET page, inside the form tags.
For mobiles, it’s better to use it
canvas.width = document.documentElement.clientWidth;
canvas.height = document.documentElement.clientHeight;
because it will display incorrectly after changing the orientation.The “viewport” will be increased when changing the orientation to portrait.See full example
