This is more an object initialzation question more than a jpa question, both methods work and you can have both of them at the same time , usually if the data member value is ready before the instantiation you use the constructor parameters, if this value could be updated after the instantiation you should have a setter.
For PySpark, you can also set the log level in your scripts with sc.setLogLevel("FATAL")
. From the docs:
Control our logLevel. This overrides any user-defined log settings. Valid log levels include: ALL, DEBUG, ERROR, FATAL, INFO, OFF, TRACE, WARN
protected void Page_PreInit(object sender, EventArgs e)
{
if (Membership.GetUser() == null) //check the user weather user is logged in or not
this.Page.MasterPageFile = "~/General.master";
else
this.Page.MasterPageFile = "~/myMaster.master";
}
Solution: under "react-native" directory: after run command "./gradlew :Examples:UIExplorer:android:app:installDebug" successfully, run commnad "./packager/packager.sh" successfuly. then click "UIExplorer App“ in the emulator or the device
The straight answer was already given: Use !!
.
However newbies often tend to overuse this operator, which is expensive in Haskell (because you work on single linked lists, not on arrays). There are several useful techniques to avoid this, the easiest one is using zip. If you write zip ["foo","bar","baz"] [0..]
, you get a new list with the indices "attached" to each element in a pair: [("foo",0),("bar",1),("baz",2)]
, which is often exactly what you need.
If you want to migrate to an Anchor Section on the same page without page jumping up use:
Just use "#/" instead of "#" e.g
<a href="#/home">Home</a>
<a href="#/about">About</a>
<a href="#/contact">contact</a> page will not jump up on click..
If you're using Rails, you can just make an empty file in the public folder and use ajax to get that. Then parse the headers for the Date header. Files in the Public folder bypass the Rails stack, and so have lower latency.
You can use Programmatic Navigation.In order to go back, you use this:
router.go(n)
Where n can be positive or negative (to go back). This is the same as history.back().So you can have your element like this:
<a @click="$router.go(-1)">back</a>
This is an old thread but for more recent Jenkins versions (in my case Jenkins 2.135) that require a particular java JDK the following should help:
Note: This is for Centos 7 , other distros may have differing directory locations although I believe they are correct for ubuntu also.
Modify /etc/sysconfig/jenkins
and set variable JENKINS_JAVA_CMD="/<your desired jvm>/bin/java"
(root access require)
Example:
JENKINS_JAVA_CMD="/usr/lib/jvm/java-1.8.0-openjdk/bin/java"
Restart Jenkins (if jenkins is run as a service sudo service jenkins stop
then sudo service jenkins start
)
The above fixed my Jenkins install not starting after I upgraded to Java 10 and Jenkins to 2.135
As an alternative to using a trigger, you might like to consider creating a stored procedure to handle the INSERT
s that takes most of the columns as arguments and gets the CURRENT_TIMESTAMP
which it includes in the final INSERT
to the database. You could do the same for the CREATE
. You may also be able to set things up so that users cannot execute INSERT
and CREATE
statements other than via the stored procedures.
I have to admit that I haven't actually done this myself so I'm not at all sure of the details.
If anyone getting below error:
Arithmetic overflow error converting expression to data type int
due to unix timestamp is in bigint (instead of int), you can use this:
SELECT DATEADD(S, CONVERT(int,LEFT(1462924862735870900, 10)), '1970-01-01')
FROM TABLE
Replace the hardcoded timestamp for your actual column with unix-timestamp
Source: MSSQL bigint Unix Timestamp to Datetime with milliseconds
You can use the https://graph.facebook.com/v3.0/{Place_your_Page_ID here}/feed?fields=id,shares,share_count&access_token={Place_your_access_token_here} to get the shares count.
Many has been said already but keep in mind that there are a times where u don't want to output all the records from the database into your select input field ..... Key example I have been working on this school management site where I have to output all the noticeboard categories in a select statement. From my controller this is the code I wrote
Noticeboard:: groupBy()->pluck('category')->get();
This way u get distinct record as they have been grouped so no repetition of records
The file can be loaded and used like this:
#!/usr/bin/env python
import ConfigParser
import io
# Load the configuration file
with open("config.yml") as f:
sample_config = f.read()
config = ConfigParser.RawConfigParser(allow_no_value=True)
config.readfp(io.BytesIO(sample_config))
# List all contents
print("List all contents")
for section in config.sections():
print("Section: %s" % section)
for options in config.options(section):
print("x %s:::%s:::%s" % (options,
config.get(section, options),
str(type(options))))
# Print some contents
print("\nPrint some contents")
print(config.get('other', 'use_anonymous')) # Just get the value
print(config.getboolean('other', 'use_anonymous')) # You know the datatype?
which outputs
List all contents
Section: mysql
x host:::localhost:::<type 'str'>
x user:::root:::<type 'str'>
x passwd:::my secret password:::<type 'str'>
x db:::write-math:::<type 'str'>
Section: other
x preprocessing_queue:::["preprocessing.scale_and_center",
"preprocessing.dot_reduction",
"preprocessing.connect_lines"]:::<type 'str'>
x use_anonymous:::yes:::<type 'str'>
Print some contents
yes
True
As you can see, you can use a standard data format that is easy to read and write. Methods like getboolean and getint allow you to get the datatype instead of a simple string.
Writing configuration
import os
configfile_name = "config.yaml"
# Check if there is already a configurtion file
if not os.path.isfile(configfile_name):
# Create the configuration file as it doesn't exist yet
cfgfile = open(configfile_name, 'w')
# Add content to the file
Config = ConfigParser.ConfigParser()
Config.add_section('mysql')
Config.set('mysql', 'host', 'localhost')
Config.set('mysql', 'user', 'root')
Config.set('mysql', 'passwd', 'my secret password')
Config.set('mysql', 'db', 'write-math')
Config.add_section('other')
Config.set('other',
'preprocessing_queue',
['preprocessing.scale_and_center',
'preprocessing.dot_reduction',
'preprocessing.connect_lines'])
Config.set('other', 'use_anonymous', True)
Config.write(cfgfile)
cfgfile.close()
results in
[mysql]
host = localhost
user = root
passwd = my secret password
db = write-math
[other]
preprocessing_queue = ['preprocessing.scale_and_center', 'preprocessing.dot_reduction', 'preprocessing.connect_lines']
use_anonymous = True
Seems not to be used at all for configuration files by the Python community. However, parsing / writing XML is easy and there are plenty of possibilities to do so with Python. One is BeautifulSoup:
from BeautifulSoup import BeautifulSoup
with open("config.xml") as f:
content = f.read()
y = BeautifulSoup(content)
print(y.mysql.host.contents[0])
for tag in y.other.preprocessing_queue:
print(tag)
where the config.xml might look like this
<config>
<mysql>
<host>localhost</host>
<user>root</user>
<passwd>my secret password</passwd>
<db>write-math</db>
</mysql>
<other>
<preprocessing_queue>
<li>preprocessing.scale_and_center</li>
<li>preprocessing.dot_reduction</li>
<li>preprocessing.connect_lines</li>
</preprocessing_queue>
<use_anonymous value="true" />
</other>
</config>
There's a way to access this information through the GitHub API.
GET /repos/:user/:repo
When retrieving information about a repository, a property named size
is valued with the size of the whole repository (including all of its history), in kilobytes.
For instance, the Git repository weights around 124 MB. The size
property of the returned JSON payload is valued to 124283
.
The size is indeed expressed in kilobytes based on the disk usage of the server-side bare repository. However, in order to avoid wasting too much space with repositories with a large network, GitHub relies on Git Alternates. In this configuration, calculating the disk usage against the bare repository doesn't account for the shared object store and thus returns an "incomplete" value through the API call.
This information has been given by GitHub support.
The normal practice is to HTML-escape any user-controlled data during redisplaying in JSP, not during processing the submitted data in servlet nor during storing in DB. In JSP you can use the JSTL (to install it, just drop jstl-1.2.jar in /WEB-INF/lib
) <c:out>
tag or fn:escapeXml
function for this. E.g.
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
...
<p>Welcome <c:out value="${user.name}" /></p>
and
<%@ taglib uri="http://java.sun.com/jsp/jstl/functions" prefix="fn" %>
...
<input name="username" value="${fn:escapeXml(param.username)}">
That's it. No need for a blacklist. Note that user-controlled data covers everything which comes in by a HTTP request: the request parameters, body and headers(!!).
If you HTML-escape it during processing the submitted data and/or storing in DB as well, then it's all spread over the business code and/or in the database. That's only maintenance trouble and you will risk double-escapes or more when you do it at different places (e.g. &
would become &amp;
instead of &
so that the enduser would literally see &
instead of &
in view. The business code and DB are in turn not sensitive for XSS. Only the view is. You should then escape it only right there in view.
You can do this in your code:
final ListView lv = (ListView) convertView.findViewById(R.id.list_view);
for (int i = 0; i < lv.getChildCount(); i++) {
((TextView)lv.getChildAt(i)).setTextColor(getResources().getColor(R.color.black));
}
Being form
a block element, you can center-align it by setting its side margins to auto:
form { margin: 0 auto; }
EDIT:
As @moomoochoo correctly pointed out, this rule will only work if the block element (your form, in this case) has been assigned a specific width.
Also, this 'trick' will not work for floating elements.
Offset Means "the amount or distance by which something is out of line". Margin or Borders are something which makes the actual height or width of an HTML element "out of line". It will help you to remember that :
- offsetHeight is a measurement in pixels of the element's CSS height, including border, padding and the element's horizontal scrollbar.
On the other hand, clientHeight is something which is you can say kind of the opposite of OffsetHeight. It doesn't include the border or margins. It does include the padding because it is something that resides inside of the HTML container, so it doesn't count as extra measurements like margin or border. So :
- clientHeight property returns the viewable height of an element in pixels, including padding, but not the border, scrollbar or margin.
ScrollHeight is all the scrollable area, so your scroll will never run over your margin or border, so that's why scrollHeight doesn't include margin or borders but yeah padding does. So:
- scrollHeight value is equal to the minimum height the element would require in order to fit all the content in the viewport without using a vertical scrollbar. The height is measured in the same way as clientHeight: it includes the element's padding, but not its border, margin or horizontal scrollbar.
Thanks. Helped me a lot. Converted to Swift 3 and worked
To save: let data = UIImagePNGRepresentation(image)
To load: let image = UIImage(data: data)
A better method is using strrpos + substr (faster than explode for that) :
$userfile_name = $_FILES['image']['name'];
$userfile_extn = substr($userfile_name, strrpos($userfile_name, '.')+1);
But, to check the type of a file, using mime_content_type is a better way : http://www.php.net/manual/en/function.mime-content-type.php
I have the same problem bu no solution yet. page-break-inside does not work on browsers but Opera. An alternative might be to use page-break-after: avoid; on all child elements of the div to keep togehter ... but in my tests, the avoid-Attribute does not work eg. in Firefox ...
What works in all ppular browsers are forced page breaks using eg. page-break-after: always
You can use lists comprehensions:
strip_list = [item.strip() for item in lines]
Or the map
function:
# with a lambda
strip_list = map(lambda it: it.strip(), lines)
# without a lambda
strip_list = map(str.strip, lines)
According to the create table statement, the default charset of the table is already utf8mb4. It seems that you have a wrong connection charset.
In Java, set the datasource url like this: jdbc:mysql://127.0.0.1:3306/testdb?useUnicode=true&characterEncoding=utf-8.
"?useUnicode=true&characterEncoding=utf-8" is necessary for using utf8mb4.
It works for my application.
You have $headers .= '...';
followed by $headers = '...';
; the second line is overwriting the first.
Just put the $headers .= "Bcc: $emailList\r\n";
say after the Content-type
line and it should be fine.
On a side note, the To
is generally required; mail servers might mark your message as spam otherwise.
$headers = "From: [email protected]\r\n" .
"X-Mailer: php\r\n";
$headers .= "MIME-Version: 1.0\r\n";
$headers .= "Content-Type: text/html; charset=ISO-8859-1\r\n";
$headers .= "Bcc: $emailList\r\n";
If the difference between endTime and startTime is greater than or equal to 60 Minutes , the statement:endTime.Subtract(startTime).Minutes;
will always return (minutesDifference % 60)
. Obviously which is not desired when we are only talking about minutes (not hours here).
Here are some of the ways if you want to get total number of minutes
(in different typecasts):
// Default value that is returned is of type *double*
double double_minutes = endTime.Subtract(startTime).TotalMinutes;
int integer_minutes = (int)endTime.Subtract(startTime).TotalMinutes;
long long_minutes = (long)endTime.Subtract(startTime).TotalMinutes;
string string_minutes = (string)endTime.Subtract(startTime).TotalMinutes;

Extreme Programming Explained: Embrace Change by Kent Beck. While I don't advocate a hardcore XP-or-the-highway take on software development, I wish I had been introduced to the principles in this book much earlier in my career. Unit testing, refactoring, simplicity, continuous integration, cost/time/quality/scope - these changed the way I looked at development. Before Agile, it was all about the debugger and fear of change requests. After Agile, those demons did not loom as large.
Yes: call the toPandas
method on your dataframe and you'll get an actual pandas dataframe !
i think using getRotationv() doesn't help because http://developer.android.com/reference/android/view/Display.html#getRotation%28%29 getRotation() Returns the rotation of the screen from its "natural" orientation.
so unless you know the "natural" orientation, rotation is meaningless.
i found an easier way,
Display display = ((WindowManager) context.getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay();
Point size = new Point();
display.getSize(size);
int width = size.x;
int height = size.y;
if(width>height)
// its landscape
please tell me if there is a problem with this someone?
If you're just after console logging here's what I'd do:
export default class App extends Component {
componentDidMount() {
console.log('I was triggered during componentDidMount')
}
render() {
console.log('I was triggered during render')
return (
<div> I am the App component </div>
)
}
}
Shouldn't be any need for those packages just to do console logging.
(Update: a few years later Google and Qwant "airlines" still send me here when searching for "git non-default ssh port") A probably better way in newer git versions is to use the GIT_SSH_COMMAND ENV.VAR like:
GIT_SSH_COMMAND="ssh -oPort=1234 -i ~/.ssh/myPrivate_rsa.key" \
git clone myuser@myGitRemoteServer:/my/remote/git_repo/path
This has the added advantage of allowing any other ssh suitable option (port, priv.key, IPv6, PKCS#11 device, ...).
User agent sniffing is really tricky and unreliable. We were trying to detect Safari on iOS with something like @qingu's answer above, it did work pretty well for Safari, Chrome and Firefox. But it falsely detected Opera and Edge as Safari.
So we went with feature detection, as it looks like as of today, serviceWorker
is only supported in Safari and not in any other browser on iOS. As stated in https://jakearchibald.github.io/isserviceworkerready/
Support does not include iOS versions of third-party browsers on that platform (see Safari support).
So we did something like
if ('serviceWorker' in navigator) {
return 'Safari';
}
else {
return 'Other Browser';
}
Note: Not tested on Safari on MacOS.
When you create a database in Microsoft SQL Server you can have multiple file groups, where storage is created in multiple places, directories or disks. Each file group can be named. The PRIMARY file group is the default one, which is always created, and so the SQL you've given creates your table ON the PRIMARY file group.
See MSDN for the full syntax.
tl;dr What to do in modern (2018) times? Assume tel:
is supported, use it and forget about anything else.
The tel:
URI scheme RFC5431 (as well as sms:
but also feed:
, maps:
, youtube:
and others) is handled by protocol handlers (as mailto:
and http:
are).
They're unrelated to HTML5 specification (it has been out there from 90s and documented first time back in 2k with RFC2806) then you can't check for their support using tools as modernizr. A protocol handler may be installed by an application (for example Skype installs a callto:
protocol handler with same meaning and behaviour of tel:
but it's not a standard), natively supported by browser or installed (with some limitations) by website itself.
What HTML5 added is support for installing custom web based protocol handlers (with registerProtocolHandler()
and related functions) simplifying also the check for their support through isProtocolHandlerRegistered()
function.
There is some easy ways to determine if there is an handler or not:" How to detect browser's protocol handlers?).
In general what I suggest is:
tel:
is supported (yes, it's not true for very old devices but IMO you can ignore them).tel:
isn't supported then change links to use callto:
and repeat check desctibed in 3.tel:
and callto:
aren't supported (or - in a desktop browser - you can't detect their support) then simply remove that link replacing URL in href
with javascript:void(0)
and (if number isn't repeated in text span) putting, telephone number in title
. Here HTML5 microdata won't help users (just search engines). Note that newer versions of Skype handle both callto:
and tel:
.Please note that (at least on latest Windows versions) there is always a - fake - registered protocol handler called App Picker (that annoying window that let you choose with which application you want to open an unknown file). This may vanish your tests so if you don't want to handle Windows environment as a special case you can simplify this process as:
tel:
is supported.tel:
with callto:
.tel:
or leave it as is (assuming there are good chances Skype is installed).Try like this
$(this).attr("src", urlAbsolute)
I encountered similar issue. The missing artifacts (jar files) exists in ~/.m2 directory and somehow eclipse is unable to find it.
For example: Missing artifact org.jdom:jdom:jar:1.1:compile
I looked through this directory ~/.m2/repository/org/jdom/jdom/1.1 and I noticed there is this file _maven.repositories. I opened it using text editor and saw the following entry:
#NOTE: This is an internal implementation file, its format can be changed without prior notice.
#Wed Feb 13 17:12:29 SGT 2013
jdom-1.1.jar>central=
jdom-1.1.pom>central=
I simply removed the "central" word from the file:
#NOTE: This is an internal implementation file, its format can be changed without prior notice.
#Wed Feb 13 17:12:29 SGT 2013
jdom-1.1.jar>=
jdom-1.1.pom>=
and run Maven > Update Project from eclipse and it just worked :) Note that your file may contain other keyword instead of "central".
The snippet you're showing doesn't seem to be directly responsible for the error.
This is how you can CAUSE the error:
namespace MyNameSpace
{
int i; <-- THIS NEEDS TO BE INSIDE THE CLASS
class MyClass
{
...
}
}
If you don't immediately see what is "outside" the class, this may be due to misplaced or extra closing bracket(s) }
.
To sort dictionary, we could make use of operator module. Here is the operator module documentation.
import operator #Importing operator module
dc = {"aa": 3, "bb": 4, "cc": 2, "dd": 1} #Dictionary to be sorted
dc_sort = sorted(dc.items(),key = operator.itemgetter(1),reverse = True)
print dc_sort
Output sequence will be a sorted list :
[('bb', 4), ('aa', 3), ('cc', 2), ('dd', 1)]
If we want to sort with respect to keys, we can make use of
dc_sort = sorted(dc.items(),key = operator.itemgetter(0),reverse = True)
Output sequence will be :
[('dd', 1), ('cc', 2), ('bb', 4), ('aa', 3)]
You have a parent element, you want to get all child of specific attribute
1. get the parent
2. get the parent nodename by using parent.nodeName.toLowerCase()
convert the nodename to lower case e.g DIV will be div
3. for further specific purpose, get an attribute of the parent e.g parent.getAttribute("id")
. this will give you id
of the parent
4. Then use document.QuerySelectorAll(paret.nodeName.toLowerCase()+"#"_parent.getAttribute("id")+" input " );
if you want input children of the parent node
let parent = document.querySelector("div.classnameofthediv")_x000D_
let parent_node = parent.nodeName.toLowerCase()_x000D_
let parent_clas_arr = parent.getAttribute("class").split(" ");_x000D_
let parent_clas_str = '';_x000D_
parent_clas_arr.forEach(e=>{_x000D_
parent_clas_str +=e+'.';_x000D_
})_x000D_
let parent_class_name = parent_clas_str.substr(0, parent_clas_str.length-1) //remove the last dot_x000D_
let allchild = document.querySelectorAll(parent_node+"."+parent_class_name+" input")
_x000D_
I'm afraid your posted example is not working, since X and Y aren't defined. So instead of pcolormesh
let's use imshow

[5, 6, 7, 8],
[9, 10, 11, 12],
[13, 14, 15, 16]]) # added some commas and array creation code
fig = plt.figure(figsize=(6, 3.2))
ax = fig.add_subplot(111)
ax.set_title('colorMap')
plt.imshow(H)
ax.set_aspect('equal')
cax = fig.add_axes([0.12, 0.1, 0.78, 0.8])
cax.get_xaxis().set_visible(False)
cax.get_yaxis().set_visible(False)

If you use GUID
as primary key and create clustered index then I suggest use the default of NEWSEQUENTIALID()
value for it.

Shell environment does not load when running remote ssh command. You can edit ssh environment file:
vi ~/.ssh/environment
Its format is:
VAR1=VALUE1
VAR2=VALUE2
Also, check sshd

You can't initialize your testArray
field this way, because the application resources still aren't ready.
Just change the code to:
package com.xtensivearts.episode.seven;
import android.app.ListActivity;
import android.os.Bundle;
import android.widget.ArrayAdapter;
public class Episode7 extends ListActivity {
String[] mTestArray;
/** Called when the activity is first created. */
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Create an ArrayAdapter that will contain all list items
ArrayAdapter<String> adapter;
mTestArray = getResources().getStringArray(R.array.testArray);
/* Assign the name array to that adapter and
also choose a simple layout for the list items */
adapter = new ArrayAdapter<String>(
this,
android.R.layout.simple_list_item_1,
mTestArray);
// Assign the adapter to this ListActivity
setListAdapter(adapter);
}
}
This is an adaptation, if anyone is curious. I needed to test whether RoboCopy successfully copied one file to multiple servers for its integrity:
$Comp = get-content c:\myfile.txt
ForEach ($PC in $Comp) {
dir "\\$PC\Folder\Share\*.*" | Select-Object $_.BaseName
}
Nice and simple, and it shows the directory and the file inside it. If you want to specify one file name or extension, just replace the *'s with whatever you want.

As 280Z28 says, for an IList<T>
you can just use the index. You could hide this in an extension method:
public static IEnumerable<T> FastReverse<T>(this IList<T> items)
{
for (int i = items.Count-1; i >= 0; i--)
{
yield return items[i];
}
}
This will be faster than Enumerable.Reverse()
which buffers all the data first. (I don't believe Reverse
has any optimisations applied in the way that Count()
does.) Note that this buffering means that the data is read completely when you first start iterating, whereas FastReverse
will "see" any changes made to the list while you iterate. (It will also break if you remove multiple items between iterations.)
For general sequences, there's no way of iterating in reverse - the sequence could be infinite, for example:
public static IEnumerable<T> GetStringsOfIncreasingSize()
{
string ret = "";
while (true)
{
yield return ret;
ret = ret + "x";
}
}
What would you expect to happen if you tried to iterate over that in reverse?

Here you go: ES5
var test = 'Hello World';
if( test.indexOf('World') >= 0){
// Found world
}
With ES6 best way would be to use includes
function to test if the string contains the looking work.
const test = 'Hello World';
if (test.includes('World')) {
// Found world

Since a stored procedure is created, altered and dropped using queries you actually CAN manage them using phpMyAdmin.
To create a stored procedure, you can use the following (change as necessary) :
CREATE PROCEDURE sp_test()
BEGIN
SELECT 'Number of records: ', count(*) from test;
END//
And make sure you set the "Delimiter" field on the SQL tab to //.
Once you created the stored procedure it will appear in the Routines fieldset below your tables (in the Structure tab), and you can easily change/drop it.
To use the stored procedure from PHP you have to execute a CALL query, just like you would do in plain SQL.

UPDATE 2019 (Swift 4):
Made a Date
extension for that. It uses NSDataDetector
instead of NSDateFormatter
.
// Just throw at it without any format.
var date: Date? = Date.FromString("02-14-2019 17:05:05")
Pretty enjoyable, it even recognizes things like "Tomorrow at 5".
XCTAssertEqual(Date.FromString("2019-02-14"), Date.FromCalendar(2019, 2, 14))
XCTAssertEqual(Date.FromString("2019.02.14"), Date.FromCalendar(2019, 2, 14))
XCTAssertEqual(Date.FromString("2019/02/14"), Date.FromCalendar(2019, 2, 14))
XCTAssertEqual(Date.FromString("2019 Feb 14"), Date.FromCalendar(2019, 2, 14))
XCTAssertEqual(Date.FromString("2019 Feb 14th"), Date.FromCalendar(2019, 2, 14))
XCTAssertEqual(Date.FromString("20190214"), Date.FromCalendar(2019, 2, 14))
XCTAssertEqual(Date.FromString("02-14-2019"), Date.FromCalendar(2019, 2, 14))
XCTAssertEqual(Date.FromString("02.14.2019 5:00 PM"), Date.FromCalendar(2019, 2, 14, 17))
XCTAssertEqual(Date.FromString("02/14/2019 17:00"), Date.FromCalendar(2019, 2, 14, 17))
XCTAssertEqual(Date.FromString("14 February 2019 at 5 hour"), Date.FromCalendar(2019, 2, 14, 17))
XCTAssertEqual(Date.FromString("02-14-2019 17:05:05"), Date.FromCalendar(2019, 2, 14, 17, 05, 05))
XCTAssertEqual(Date.FromString("17:05, 14 February 2019 (UTC)"), Date.FromCalendar(2019, 2, 14, 17, 05))
XCTAssertEqual(Date.FromString("02-14-2019 17:05:05 GMT"), Date.FromCalendar(2019, 2, 14, 17, 05, 05))
XCTAssertEqual(Date.FromString("02-13-2019 Tomorrow"), Date.FromCalendar(2019, 2, 14))
XCTAssertEqual(Date.FromString("2019 Feb 14th Tomorrow at 5"), Date.FromCalendar(2019, 2, 14, 17))
Goes like:
extension Date
{
public static func FromString(_ dateString: String) -> Date?
{
// Date detector.
let detector = try! NSDataDetector(types: NSTextCheckingResult.CheckingType.date.rawValue)
// Enumerate matches.
var matchedDate: Date?
var matchedTimeZone: TimeZone?
detector.enumerateMatches(
in: dateString,
options: [],
range: NSRange(location: 0, length: dateString.utf16.count),
using:
{
(eachResult, _, _) in
// Lookup matches.
matchedDate = eachResult?.date
matchedTimeZone = eachResult?.timeZone
// Convert to GMT (!) if no timezone detected.
if matchedTimeZone == nil, let detectedDate = matchedDate
{ matchedDate = Calendar.current.date(byAdding: .second, value: TimeZone.current.secondsFromGMT(), to: detectedDate)! }
})
// Result.
return matchedDate
}
}
UPDATE 2014:
Made an NSString extension for that.
// Simple as this.
date = dateString.dateValue;
Thanks to NSDataDetector, it recognizes a whole lot of format.

ORIGINAL ANSWER 2013:
Whether you're not sure (or don't care) about the date format contained in the string, use NSDataDetector for parsing date.
//Role players.
NSString *dateString = @"Wed, 03 Jul 2013 02:16:02 -0700";
__block NSDate *detectedDate;
//Detect.
NSDataDetector *detector = [NSDataDetector dataDetectorWithTypes:NSTextCheckingAllTypes error:nil];
[detector enumerateMatchesInString:dateString
options:kNilOptions
range:NSMakeRange(0, [dateString length])
usingBlock:^(NSTextCheckingResult *result, NSMatchingFlags flags, BOOL *stop)
{ detectedDate = result.date; }];
If both application have the same signature (meaning that both APPS are yours and signed with the same key), you can call your other app activity as follows:
Intent LaunchIntent = getActivity().getPackageManager().getLaunchIntentForPackage(CALC_PACKAGE_NAME);
startActivity(LaunchIntent);
Hope it helps.
to use in onMenuItemClick(MenuItem item)
just do invalidateOptionsMenu();
item.setIcon(ContextCompat.getDrawable(this, R.drawable.ic_baseline_play_circle_outline_24px));
The problem is that you're trying to print an unicode character to a possibly non-unicode terminal. You need to encode it with the 'replace
option before printing it, e.g. print ch.encode(sys.stdout.encoding, 'replace')
.
As others have pointed out, the accepted answer does not return both x86 and x64 installs. Below is my solution for that. It creates a StringBuilder
, appends the registry values to it (with formatting), and writes its output to a text file:
const string FORMAT = "{0,-100} {1,-20} {2,-30} {3,-8}\n";
private void LogInstalledSoftware()
{
var line = string.Format(FORMAT, "DisplayName", "Version", "Publisher", "InstallDate");
line += string.Format(FORMAT, "-----------", "-------", "---------", "-----------");
var sb = new StringBuilder(line, 100000);
ReadRegistryUninstall(ref sb, RegistryView.Registry32);
sb.Append($"\n[64 bit section]\n\n{line}");
ReadRegistryUninstall(ref sb, RegistryView.Registry64);
File.WriteAllText(@"c:\temp\log.txt", sb.ToString());
}
private static void ReadRegistryUninstall(ref StringBuilder sb, RegistryView view)
{
const string REGISTRY_KEY = @"SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall";
using var baseKey = RegistryKey.OpenBaseKey(RegistryHive.LocalMachine, view);
using var subKey = baseKey.OpenSubKey(REGISTRY_KEY);
foreach (string subkey_name in subKey.GetSubKeyNames())
{
using RegistryKey key = subKey.OpenSubKey(subkey_name);
if (!string.IsNullOrEmpty(key.GetValue("DisplayName") as string))
{
var line = string.Format(FORMAT,
key.GetValue("DisplayName"),
key.GetValue("DisplayVersion"),
key.GetValue("Publisher"),
key.GetValue("InstallDate"));
sb.Append(line);
}
key.Close();
}
subKey.Close();
baseKey.Close();
}
You need the path of the plugins directory of your local GATE install. So if Gate is installed in "/home/user/GATE_Developer_8.1", the code looks like this:
System.setProperty("gate.home", "/home/user/GATE_Developer_8.1/plugins");
You don't have to set gate.home from the command line. You can set it in your application, as long as you set it BEFORE you call Gate.init().
After installing socket.io-client:
npm install socket.io-client
This is how the client code looks like:
var io = require('socket.io-client'),
socket = io.connect('localhost', {
port: 1337
});
socket.on('connect', function () { console.log("socket connected"); });
socket.emit('private message', { user: 'me', msg: 'whazzzup?' });
Thanks alessioalex.
The runas command does not allow a password on its command line. This is by design (and also the reason you cannot pipe a password to it as input). Raymond Chen says it nicely:
The RunAs program demands that you type the password manually. Why doesn't it accept a password on the command line?
This was a conscious decision. If it were possible to pass the password on the command line, people would start embedding passwords into batch files and logon scripts, which is laughably insecure.
In other words, the feature is missing to remove the temptation to use the feature insecurely.
According to this site, this is supported in the playbackRate
and defaultPlaybackRate
attributes, accessible via the DOM. Example:
/* play video twice as fast */
document.querySelector('video').defaultPlaybackRate = 2.0;
document.querySelector('video').play();
/* now play three times as fast just for the heck of it */
document.querySelector('video').playbackRate = 3.0;
The above works on Chrome 43+, Firefox 20+, IE 9+, Edge 12+.
Use the 64 bit version only if you have to work with heavy amounts of data, in that scenario, the 64 bits performs better with the inconvenient that John La Rooy said; if not, stick with the 32 bits.
The max length property is camel-cased: maxLength
jQuery doesn't come with a maxlength method by default. Also, your document ready function isn't technically correct:
$(document).ready(function () {
$("#ms_num")[0].maxLength = 6;
// OR:
$("#ms_num").attr('maxlength', 6);
// OR you can use prop if you are using jQuery 1.6+:
$("#ms_num").prop('maxLength', 6);
});
Also, since you are using jQuery, you can rewrite your code like this (taking advantage of jQuery 1.6+):
$('input').each(function (index) {
var element = $(this);
if (index === 1) {
element.prop('maxLength', 3);
} else if (element.is(':radio') || element.is(':checkbox')) {
element.prop('maxLength', 5);
}
});
$(function() {
$("#ms_num").prop('maxLength', 6);
});
if you're using the compiled bootstrap, one of the ways of fixing it is by editing the bootstrap.min.js before the line
$next[0].offsetWidth
force reflow Change to
if (typeof $next == 'object' && $next.length) $next[0].offsetWidth // force reflow
In case your UIViewController is inside a UINavigationController you will have to set the BarStyle:
-[UINavigationBar setBarStyle:UIBarStyleBlack]

Take a look at my jquery videoBG plugin
http://syddev.com/jquery.videoBG/
Make any HTML5 video a site background... has an image fallback for browsers that don't support html5
Really easy to use
Let me know if you need any help.
Another example just using a basic loop and index check
HTML
<ul id="foo">
<li>0</li>
<li>1</li>
<li>2</li>
<li>3</li>
<li>4</li>
</ul>
JavaScript runs onload/ready or after ul is rendered
var list = document.getElementById("foo"),
items = list.getElementsByTagName("li");
list.onclick = function(e) {
var evt = e || window.event,
src = evt.target || evt.srcElement;
var myIndex = findIndex(src);
alert(myIndex);
};
function findIndex( elem ) {
var i, len = items.length;
for(i=0; i<len; i++) {
if (items[i]===elem) {
return i;
}
}
return -1;
}
Running Example
Declare where display: flex;
was given Element.
align-items: center;
You don't want to delete if you're wanting to leave the row itself intact. You want to update the row, and change the column value.
The general form for this would be an UPDATE
statement:
UPDATE <table name>
SET
ColumnA = <NULL, or '', or whatever else is suitable for the new value for the column>
WHERE
ColumnA = <bad value> /* or any other search conditions */
I had the same issue the solution for me was to change my java version in the pom.xml file.
Shell variables have no type, so the simplest way is to use the return type test
command:
if [ $var -eq $var 2> /dev/null ]; then ...
(Or else parse it with a regexp)
This is the error line:
if (called_from.equalsIgnoreCase("add")) { --->38th error line
This means that called_from
is null. Simple check if it is null above:
String called_from = getIntent().getStringExtra("called");
if(called_from == null) {
called_from = "empty string";
}
if (called_from.equalsIgnoreCase("add")) {
// do whatever
} else {
// do whatever
}
That way, if called_from
is null, it'll execute the else
part of your if statement.
It looks like details
is an array of hashes. So item
inside of your block will be the whole hash. Therefore, to check the :qty
key, you'd do something like the following:
details.select{ |item| item[:qty] != "" }
That will give you all items where the :qty
key isn't an empty string.
<?php
header('Content-type: text/plain');
header('Content-Disposition: attachment;
filename="<name for the created file>"');
/*
assign file content to a PHP Variable $content
*/
echo $content;
?>
It means "a python object", i.e. not one of the builtin scalar types supported by numpy.
np.array([object()]).dtype
=> dtype('O')
Here are my observation, firstly you need to include the header math.h
as sqrt()
function declared in math.h
header file. For e.g
#include <math.h>
secondly, if you read manual page of sqrt you will notice this line Link with -lm.
#include <math.h> /* header file you need to include */
double sqrt(double x); /* prototype of sqrt() function */
Link with -lm. /* Library linking instruction */
But application still says undefined reference to sqrt. Do you see any problem here?
Compiler error is correct as you haven't linked your program with library lm
& linker is unable to find reference of sqrt()
, you need to link it explicitly. For e.g
gcc -Wall -Wextra -Werror -pedantic test.c -lm
JSFiddle wraps your code in a function, so start()
is not defined in the global scope.
Moral of the story: don't use inline event bindings. Use addEventListener
/attachEvent
.
Please don't pass strings to setTimeout
and setInterval
. It's eval
in disguise.
Use a function instead, and get cozy with var
and white space:
var input = document.getElementById("input"),
add;
function start() {
add = setInterval(function() {
input.value++;
}, 1000);
}
start();

It seems like the $in
operator would serve your purposes just fine.
You could do something like this (pseudo-query):
if (db.courses.find({"students" : {"$in" : [studentId]}, "course" : courseId }).count() > 0) {
// student is enrolled in class
}
Alternatively, you could remove the "course" : courseId
clause and get back a set of all classes the student is enrolled in.
If you're just looking for an actual regex that allows for various dots, underscores and dashes, it as follows: [a-zA-z0-9.-]+\@[a-zA-z0-9.-]+.[a-zA-Z]+
. That will allow a fairly stupid looking email like tom_anderson.1-neo@my-mail_matrix.com
to be validated.
Consider the figure enclosed in this other question.
ebp-4
is your first local variable and, seen as a dword pointer, it is the address of a 32 bit integer that has to be cleared.
Maybe your source starts with
Object x = null;
Also you can check using Keras backend function:
from keras import backend as K
K.tensorflow_backend._get_available_gpus()
I test this on Keras (2.1.1)
Try this:
Sometimes the port is changed and generated error.
I was dealing with same error and after spending time solved it by adding below lines in web.config file

a thorough reading of jQuery AJAX cross domain seems to indicate that the server you are querying is returning a header string that prohibits cross-domain json requests. Check the headers of the response you are receiving to see if the Access-Control-Allow-Origin header is set, and whether its value restricts cross-domain requests to the local host.
System.getProperty("user.name") is not a good security option since that environment variable could be faked: C:\ set USERNAME="Joe Doe" java ... // will give you System.getProperty("user.name") You ought to do:
com.sun.security.auth.module.NTSystem NTSystem = new com.sun.security.auth.module.NTSystem();
System.out.println(NTSystem.getName());
JDK 1.5 and greater.
I use it within an applet, and it has to be signed. info source
I try to give a broad picture with this answer.
The following thoughts in brackets was my belief until I have just recently tested the issue:
[[In terms of low level languages like C/C++, the code is compiled so that the processor has a special conditional jump command when a variable is zero (or non-zero).
Also, if you care about this much optimization, you could go ++i
instead of i++
, because ++i
is a single processor command whereas i++
means j=i+1, i=j
.]]
Really fast loops can be done by unrolling them:
for(i=800000;i>0;--i)
do_it(i);
It can be way slower than
for(i=800000;i>0;i-=8)
{
do_it(i); do_it(i-1); do_it(i-2); ... do_it(i-7);
}
but the reasons for this can be quite complicated (just to mention, there are the issues of processor command preprocessing and cache handling in the game).
In terms of high level languages, like JavaScript as you asked, you can optimize things if you rely on libraries, built-in functions for looping. Let them decide how it is best done.
Consequently, in JavaScript, I would suggest using something like
array.forEach(function(i) {
do_it(i);
});
It is also less error-prone and browsers have a chance to optimize your code.
[REMARK: not only the browsers, but you too have a space to optimize easily, just redefine the forEach
function (browser dependently) so that it uses the latest best trickery! :) @A.M.K. says in special cases it is worth rather using array.pop
or array.shift
. If you do that, put it behind the curtain. The utmost overkill is to add options to forEach
to select the looping algorithm.]
Moreover, also for low level languages, the best practice is to use some smart library function for complex, looped operations if it is possible.
Those libraries can also put things (multi-threaded) behind your back and also specialized programmers keep them up-to-date.
I did a bit more scrutiny and it turns out that in C/C++,
even for 5e9 = (50,000x100,000) operations, there is no difference between going up and down if the testing is done against a constant like @alestanis says. (JsPerf results are sometimes inconsistent but by and large say the same: you can't make a big difference.)
So --i
happens to be rather a "posh" thing. It only makes you look like a better programmer. :)
On the other hand, for-unrolling in this 5e9 situation, it has brought me down from 12 sec to 2.5 sec when I went by 10s, and to 2.1 sec when I went by 20s. It was without optimization, and optimization has brought things down to unmeasureable little time. :) (Unrolling can be done in my way above or using i++
, but that does not bring things ahead in JavaScript. )
All in all: keep i--
/i++
and ++i
/i++
differences to the job interviews, stick to array.forEach
or other complex library functions when available. ;)
I fixed this by changing JAVA_HOME from x86 to x64. Maven was running on x86 but node was using x64. Remove /node and /node_modules and build again.
This code is for the headset profiles, probably it will work for other profiles too. First you need to provide profile listener (Kotlin code):
private val mProfileListener = object : BluetoothProfile.ServiceListener {
override fun onServiceConnected(profile: Int, proxy: BluetoothProfile) {
if (profile == BluetoothProfile.HEADSET)
mBluetoothHeadset = proxy as BluetoothHeadset
}
override fun onServiceDisconnected(profile: Int) {
if (profile == BluetoothProfile.HEADSET) {
mBluetoothHeadset = null
}
}
}
Then while checking bluetooth:
mBluetoothAdapter.getProfileProxy(context, mProfileListener, BluetoothProfile.HEADSET)
if (!mBluetoothAdapter.isEnabled) {
return Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE)
}
It takes a bit of time until onSeviceConnected is called. After that you may get the list of the connected headset devices from:
mBluetoothHeadset!!.connectedDevices
If you have your hex value, and your just wondering what the value for the alpha would be, this snippet may help:
const alphaToHex = (alpha => {_x000D_
if (alpha > 1 || alpha < 0 || isNaN(alpha)) {_x000D_
throw new Error('The argument must be a number between 0 and 1');_x000D_
}_x000D_
return Math.ceil(255 * alpha).toString(16).toUpperCase();_x000D_
})_x000D_
_x000D_
console.log(alphaToHex(0.45));
_x000D_
Alternative ASP.NET MVC 5 Fix:
In my case the error was occurring during the request. Best approach in my scenario is modifying the actual JsonValueProviderFactory
which applies the fix to the global project and can be done by editing the global.cs
file as such.
JsonValueProviderConfig.Config(ValueProviderFactories.Factories);
add a web.config entry:
<add key="aspnet:MaxJsonLength" value="20971520" />
and then create the two following classes
public class JsonValueProviderConfig
{
public static void Config(ValueProviderFactoryCollection factories)
{
var jsonProviderFactory = factories.OfType<JsonValueProviderFactory>().Single();
factories.Remove(jsonProviderFactory);
factories.Add(new CustomJsonValueProviderFactory());
}
}
This is basically an exact copy of the default implementation found in System.Web.Mvc
but with the addition of a configurable web.config appsetting value aspnet:MaxJsonLength
.
public class CustomJsonValueProviderFactory : ValueProviderFactory
{
/// <summary>Returns a JSON value-provider object for the specified controller context.</summary>
/// <returns>A JSON value-provider object for the specified controller context.</returns>

{

}
}

We just released pako https://github.com/nodeca/pako , port of zlib to javascript. I think that's now the fastest js implementation of deflate / inflate / gzip / ungzip. Also, it has democratic MIT licence. Pako supports all zlib options and it's results are binary equal.
Example:
var inflate = require('pako/lib/inflate').inflate;
var text = inflate(zipped, {to: 'string'});
According to the documentation on here http://angularjs.blogspot.co.uk/2017/03/angular-400-now-available.html you 'should' just be able to run...
npm install @angular/{common,compiler,compiler-cli,core,forms,http,platform-browser,platform-browser-dynamic,platform-server,router,animations}@latest typescript@latest --save
I tried it and got a couple of errors due to my zone.js and ngrx/store libraries being older versions.
Updating those to the latest versions npm install zone.js@latest --save
and npm install @ngrx/store@latest -save
, then running the angular install again worked for me.
I seconded Matthieu answer
I commented #Listen 443 in httpd-ssl file and apache can be started
Because the file already has VirtualHost default:443
Well if you really wanted to make it one line without importing anything you could do:
eval('*'.join(str(item) for item in list))
But don't.
Once you have Selected a group of sheets, you can use Selection
Consider:
Sub luxation()
ThisWorkbook.Sheets(Array("Sheet1", "Sheet2", "Sheet3")).Select
Selection.ExportAsFixedFormat _
Type:=xlTypePDF, _
Filename:="C:\TestFolder\temp.pdf", _
Quality:=xlQualityStandard, _
IncludeDocProperties:=True, _
IgnorePrintAreas:=False, _
OpenAfterPublish:=True
End Sub
EDIT#1:
Further testing has reveled that this technique depends on the group of cells selected on each worksheet. To get a comprehensive output, use something like:
Sub Macro1()
Sheets("Sheet1").Activate
ActiveSheet.UsedRange.Select
Sheets("Sheet2").Activate
ActiveSheet.UsedRange.Select
Sheets("Sheet3").Activate
ActiveSheet.UsedRange.Select
ThisWorkbook.Sheets(Array("Sheet1", "Sheet2", "Sheet3")).Select
Selection.ExportAsFixedFormat Type:=xlTypePDF, Filename:= _
"C:\Users\James\Desktop\pdfmaker.pdf", Quality:=xlQualityStandard, _
IncludeDocProperties:=True, IgnorePrintAreas:=False, OpenAfterPublish:= _
True
End Sub
I'm using this without any additional settings:
if (!$st->execute()) {
print_r($st->errorInfo());
}
Angular CLI now uses environment files to do this.
First, add an environments
section to the angular-cli.json
Something like :
{
"apps": [{
"environments": {
"prod": "environments/environment.prod.ts"
}
}]
}
And then inside the environment file (environments/environment.prod.ts
in this case), add something like :
export const environment = {
production: true,
"output-path": "./whatever/dist/"
};
now when you run :
ng build --prod
it will output to the ./whatever/dist/
folder.
const
is equivalent to #define
but only for value statements(e.g. #define myvalue = 2
). The value declared replaces the name of the variable before compilation.
static
is a variable. The value can change, but the variable will persist throughout the execution of the program even if the variable is declared in a function. It is equivalent to a global variable who's usage scope is the scope of the block they have been declared in, but their value's scope is global.
As such, static variables are only initialized once. This is especially important if the variable is declared in a function, since it guarantees the initialization will only take place at the first call to the function.
Another usage of statics involves objects. Declaring a static variable in an object has the effect that this value is the same for all instances of the object. As such, it cannot be called with the object's name, but only with the class's name.
public class Test
{
public static int test;
}
Test myTestObject=new Test();
myTestObject.test=2;//ERROR
Test.test=2;//Correct
In languages like C and C++, it is meaningless to declare static global variables, but they are very useful in functions and classes. In managed languages, the only way to have the effect of a global variable is to declare it as static.
final Fragment fragment1 = new fragment1();
final Fragment fragment2 = new fragment2();
final FragmentManager fm = getSupportFragmentManager();

In onCreate, after setContentView, i hid two fragments and committed them to the fragment manager, but i didn't hide the first fragment that will serve as home.
fm.beginTransaction().add(R.id.main_container, fragment2, "2").hide(fragment2).commit();
fm.beginTransaction().add(R.id.main_container,fragment1, "1").commit();

You can create a jQuery function to unload Bootstrap CSS files at the size of 768px, and load it back when resized to lower width. This way you can design a mobile website without touching the desktop version, by using col-xs-* only
function resize() {
if ($(window).width() > 767) {
$('link[rel=stylesheet][href~="bootstrap.min.css"]').prop('disabled', true);
$('link[rel=stylesheet][href~="bootstrap-theme.min.css"]').prop('disabled', true);
}
else {
$('link[rel=stylesheet][href~="bootstrap.min.css"]').prop('disabled', false);
$('link[rel=stylesheet][href~="bootstrap-theme.min.css"]').prop('disabled', false);
}
}
and
$(document).ready(function() {
$(window).resize(resize);
resize();
if ($(window).width() > 767) {
$('link[rel=stylesheet][href~="bootstrap.min.css"]').prop('disabled', true);
$('link[rel=stylesheet][href~="bootstrap-theme.min.css"]').prop('disabled', true);
}
});
May I suggest that you initialize your "max and min so far" variables not to infinity, but to the first number in the array?
The Dart language has aspects of functional programming, so what you want can be written concisely as:
List<String> list = ['one', 'two', 'three', 'four'];
List<Widget> widgets = list.map((name) => new Text(name)).toList();
Read this as "take each name
in list
and map it to a Text
and form them back into a List
".
I also Had to filter based on the URL pattern(/{servicename}/api/stats/)in java code .
if (path.startsWith("/{servicename}/api/statistics/")) {
validatingAuthToken(((HttpServletRequest) request).getHeader("auth_token"));
filterChain.doFilter(request, response);
}
But its bizarre, that servlet doesn't support url pattern other than (/*), This should be a very common case for servlet API's !
I had a more specifc error message that stated to remove 'Office 16 Click-to-Run Extensibility Component'

cballou's solution will work if you are using an old version of jquery. In newer versions you can also try:
$.ajax({
type: 'POST',
url:'url.do',
data: formData,
success: function(data, textStatus, request){
alert(request.getResponseHeader('some_header'));
},
error: function (request, textStatus, errorThrown) {
alert(request.getResponseHeader('some_header'));
}
});
According to docs the XMLHttpRequest object is available as of jQuery 1.4.
To save others a few seconds, and to save them from having to read the manual, here's the short answer. Add this to the top of your make file:
.DEFAULT_GOAL := mytarget
mytarget will now be the target that is run if "make" is executed and no target is specified.
If you have an older version of make (<= 3.80), this won't work. If this is the case, then you can do what anon mentions, simply add this to the top of your make file:
.PHONY: default
default: mytarget ;

I don't have much knowledge about C2DM. Use GCM, it's very easy to implement and configure.
Just watch out for any spaces or errors in your arguments/command. The mvn error message may not be so descriptive but I have realised, usually spaces/omissions can also cause that error.
Use the %
operator with a string:
irb(main):001:0> "%03d" % 5
=> "005"
The left-hand-side is a printf format string, and the right-hand side can be a list of values, so you could do something like:
irb(main):002:0> filename = "%s/%s.%04d.txt" % ["dirname", "filename", 23]
=> "dirname/filename.0023.txt"
Here's a printf format cheat sheet you might find useful in forming your format string. The printf format is originally from the C
function printf
, but similar formating functions are available in perl, ruby, python, java, php, etc.
There are many ways using them you can enable/disable any element :
Approach 1
$("#txtName").attr("disabled", true);
Approach 2
$("#txtName").attr("disabled", "disabled");
If you are using jQuery 1.7 or higher version then use prop(), instead of attr().
$("#txtName").prop("disabled", "disabled");
If you wish to enable any element then you just have to do opposite of what you did to make it disable. However jQuery provides another way to remove any attribute.
Approach 1
$("#txtName").attr("disabled", false);
Approach 2
$("#txtName").attr("disabled", "");
Approach 3
$("#txtName").removeAttr("disabled");
Again, if you are using jQuery 1.7 or higher version then use prop(), instead of attr(). That's is. This is how you enable or disable any element using jQuery.
You could follow maven's standard project layout. You don't have to actually use maven, but it would make the transition easier in the future (if necessary). Plus, other developers will be used to seeing that layout, since many open source projects are layed out this way,
The only thing that worked for me was:
git reset --hard HEAD~5
This will take you back five commits and then with
git pull
I found that by looking up how to undo a Git merge.
You can just try to download data, and if connection fail you will know that somethings with connection isn't fine.
Basically you can't check if computer is connected to internet. There can be many reasons for failure, like wrong DNS configuration, firewalls, NAT. So even if you make some tests, you can't have guaranteed that you will have connection with your API until you try.
This is how you use the TensorBoard callback:
from keras.callbacks import TensorBoard
tensorboard = TensorBoard(log_dir='./logs', histogram_freq=0,
write_graph=True, write_images=False)
# define model
model.fit(X_train, Y_train,
batch_size=batch_size,
epochs=nb_epoch,
validation_data=(X_test, Y_test),
shuffle=True,
callbacks=[tensorboard])
The value of hjust
and vjust
are only defined between 0 and 1:
Source: ggplot2, Hadley Wickham, page 196
(Yes, I know that in most cases you can use it beyond this range, but don't expect it to behave in any specific way. This is outside spec.)
hjust
controls horizontal justification and vjust
controls vertical justification.
An example should make this clear:
td <- expand.grid(
hjust=c(0, 0.5, 1),
vjust=c(0, 0.5, 1),
angle=c(0, 45, 90),
text="text"
)
ggplot(td, aes(x=hjust, y=vjust)) +
geom_point() +
geom_text(aes(label=text, angle=angle, hjust=hjust, vjust=vjust)) +
facet_grid(~angle) +
scale_x_continuous(breaks=c(0, 0.5, 1), expand=c(0, 0.2)) +
scale_y_continuous(breaks=c(0, 0.5, 1), expand=c(0, 0.2))
To understand what happens when you change the hjust
in axis text, you need to understand that the horizontal alignment for axis text is defined in relation not to the x-axis, but to the entire plot (where this includes the y-axis text). (This is, in my view, unfortunate. It would be much more useful to have the alignment relative to the axis.)
DF <- data.frame(x=LETTERS[1:3],y=1:3)
p <- ggplot(DF, aes(x,y)) + geom_point() +
ylab("Very long label for y") +
theme(axis.title.y=element_text(angle=0))
p1 <- p + theme(axis.title.x=element_text(hjust=0)) + xlab("X-axis at hjust=0")
p2 <- p + theme(axis.title.x=element_text(hjust=0.5)) + xlab("X-axis at hjust=0.5")
p3 <- p + theme(axis.title.x=element_text(hjust=1)) + xlab("X-axis at hjust=1")
library(ggExtra)
align.plots(p1, p2, p3)
To explore what happens with vjust
aligment of axis labels:
DF <- data.frame(x=c("a\na","b","cdefghijk","l"),y=1:4)
p <- ggplot(DF, aes(x,y)) + geom_point()
p1 <- p + theme(axis.text.x=element_text(vjust=0, colour="red")) +
xlab("X-axis labels aligned with vjust=0")
p2 <- p + theme(axis.text.x=element_text(vjust=0.5, colour="red")) +
xlab("X-axis labels aligned with vjust=0.5")
p3 <- p + theme(axis.text.x=element_text(vjust=1, colour="red")) +
xlab("X-axis labels aligned with vjust=1")
library(ggExtra)
align.plots(p1, p2, p3)
I'm using out of the box MVC4 with this code (note the two parameters inside ToDictionary
)
var result = new JsonResult()
{
Data = new
{
partials = GetPartials(data.Partials).ToDictionary(x => x.Key, y=> y.Value)
}
};
I get what's expected:
{"partials":{"cartSummary":"\u003cb\u003eCART SUMMARY\u003c/b\u003e"}}
Important: WebAPI in MVC4 uses JSON.NET serialization out of the box, but the standard web JsonResult
action result doesn't. Therefore I recommend using a custom ActionResult to force JSON.NET serialization. You can also get nice formatting
Here's a simple actionresult JsonNetResult
http://james.newtonking.com/archive/2008/10/16/asp-net-mvc-and-json-net.aspx
You'll see the difference (and can make sure you're using the right one) when serializing a date:
Microsoft way:
{"wireTime":"\/Date(1355627201572)\/"}
JSON.NET way:
{"wireTime":"2012-12-15T19:07:03.5247384-08:00"}
Post is the most secured along with SSL installed because its transmitted in the message body.
But all of these methods are insecure because the 7 bit protocol it uses underneath it is hack-able with escapement. Even through a level 4 web application firewall.
Sockets are no guarantee either... Even though its more secure in certain ways.
For your literal example you'd want to use the adjacent selector (+).
h4 + p {color:red}//any <p> that is immediately preceded by an <h4>
<h4>Some text</h4>
<p>I'm red</p>
<p>I'm not</p>
However, if you wanted to select all successive paragraphs, you'd need to use the general sibling selector (~).
h4 ~ p {color:red}//any <p> that has the same parent as, and comes after an <h4>
<h4>Some text</h4>
<p>I'm red</p>
<p>I am too</p>

See 7.19.6.1/7 in the C99 standard, or the more convenient POSIX documentation of formatting codes:
http://pubs.opengroup.org/onlinepubs/009695399/functions/fprintf.html
If your implementation doesn't support those formatting codes (for example because you're on C89), then you have a bit of a problem since AFAIK there aren't integer types in C89 that have formatting codes and are guaranteed to be as big as these types. So you need to do something implementation-specific.
For example if your compiler has long long
and your standard library supports %lld
, you can confidently expect that will serve in place of intmax_t
. But if it doesn't, you'll have to fall back to long
, which would fail on some other implementations because it's too small.

Map<String, Integer> wordMap = new LinkedHashMap<String, Integer>();
for (int i = 0; i < originalSplit.length - 1; i++) {

Try width:inherit
to make the image take the width of it's container <div>
. It will stretch/shrink it's height to maintain proportion. Don't set the height in the <div>
, it will size to fit the image height.
img {
width:inherit;
}
.item {
border:1px solid pink;
width: 120px;
float: left;
margin: 3px;
padding: 3px;
}
I was able to achieve that by wrapping Button
with ConstraintLayout
:
<androidx.coordinatorlayout.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_height="wrap_content"
app:elevation="0dp">
<androidx.appcompat.widget.Toolbar

You may create a drawable resourcebutton_publish_rounded
, define the button properties and assign this file to button's android:background
property:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="@color/green" />
<corners android:radius="100dp" />

Really just answering to add a link which I'm surprised hasn't been mentioned yet: Eric's Lippert's blog entry on "Arrays considered somewhat harmful."
You can judge from the title that it's suggesting using collections wherever practical - but as Marc rightly points out, there are plenty of places where an array really is the only practical solution.
For future visitors.
As of now Android 4.2.2 platform includes Google Play services. Just use an emulator running Jelly Bean. Details can be found here:
Setup Google Play Services SDK
EDIT:
Another option is to use Genymotion (runs way faster)
EDIT 2:
As @gdw2 commented: "setting up the Google Play Services SDK does not install a working Google Play app -- it just enables certain services provided by the SDK"
After version 2.0 Genymotion does not come with Play Services by default, but it can be easily installed manually. Just download the right version from here and drag and drop into the virtual device (emulador).
Whilst this an old question, I ran into this problem myself recently and some of the answers here are now deprecated (as the comments point out). So for the benefit of others who may have stumbled here:
A term
query can be used to find the exact term specified in the reverse index:
{
"query": {
"term" : { "tags" : "a" }
}
From the documenation https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-term-query.html
Alternatively you can use a terms
query, which will match all documents with any of the items specified in the given array:
{
"query": {
"terms" : { "tags" : ["a", "c"]}
}
https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-terms-query.html
One gotcha to be aware of (which caught me out) - how you define the document also makes a difference. If the field you're searching in has been indexed as a text
type then Elasticsearch will perform a full text search (i.e using an analyzed
string).
If you've indexed the field as a keyword
then a keyword search using a 'non-analyzed' string is performed. This can have a massive practical impact as Analyzed strings are pre-processed (lowercased, punctuation dropped etc.) See (https://www.elastic.co/guide/en/elasticsearch/guide/master/term-vs-full-text.html)
To avoid these issues, the string field has split into two new types: text, which should be used for full-text search, and keyword, which should be used for keyword search. (https://www.elastic.co/blog/strings-are-dead-long-live-strings)
There is no command to do it (like you would do it with MySQL for instance). The number of Redis databases is fixed, and set in the configuration file. By default, you have 16 databases. Each database is identified by a number (not a name).
You can use the following command to know the number of databases:
CONFIG GET databases
1) "databases"
2) "16"
You can use the following command to list the databases for which some keys are defined:
INFO keyspace
# Keyspace
db0:keys=10,expires=0
db1:keys=1,expires=0
db3:keys=1,expires=0
Please note that you are supposed to use the "redis-cli" client to run these commands, not telnet. If you want to use telnet, then you need to run these commands formatted using the Redis protocol.
For instance:
*2
$4
INFO
$8
keyspace
$79
# Keyspace
db0:keys=10,expires=0
db1:keys=1,expires=0
db3:keys=1,expires=0
You can find the description of the Redis protocol here: http://redis.io/topics/protocol
You can increase the memory allowed to php script by executing the following line above all the codes in the script:
ini_set('memory_limit','-1'); // enabled the full memory available.
And also de allocate the unwanted variables in the script.
Check this php library : Freeing memory with PHP
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%'
IDENTIFIED BY 'YOUR_PASS'
WITH GRANT OPTION;
FLUSH PRIVILEGES;
*.* = DB.TABLE
you can restrict user to specific database and specific table.
'root'@'%'
you can change root with any user you created and % is to allow all IP. You can restrict it by changing %.168.1.1 etc too.
If that doesn't resolve, then also modify my.cnf or my.ini and comment these lines

skip-networking
to #skip-networking

On my PC (Core i7 860 - it is doing nothing much apart from reading on my smartphone):
n += i*i
then n*2
is first2 * (i * i)
is second.The JVM is clearly not optimizing the same way than a human does (based on Runemoro's answer).
Now then, reading bytecode: javap -c -v ./target/classes/org/sample/MyBenchmark.class
I am not expert on bytecode, but we iload_2
before we imul
: that's probably where you get the difference: I can suppose that the JVM optimize reading i
twice (i
is already here, and there is no need to load it again) whilst in the 2*i*i
it can't.
Mongo includes a mongoexport utility (see docs) which can dump a collection. This utility uses the native libmongoclient and is likely the fastest method.
mongoexport -d <database> -c <collection_name>
Also helpful:
-o
: write the output to file, otherwise standard output is used (docs)
--jsonArray
: generates a valid json document, instead of one json object per line (docs)
--pretty
: outputs formatted json (docs)
The only effective mechanism for passing parameters into a build is to use Java properties:
ant -Done=1 -Dtwo=2
The following example demonstrates how you can check and ensure the expected parameters have been passed into the script
<project name="check" default="build">
<condition property="params.set">
<and>
<isset property="one"/>
<isset property="two"/>
</and>
</condition>
<target name="check">
<fail unless="params.set">
Must specify the parameters: one, two
</fail>
</target>
<target name="build" depends="check">
<echo>
one = ${one}
two = ${two}
</echo>
</target>
</project>
Given the already proposed options the easiest solution without finding a parent:
var parent = document.createElement("div");
var child = parent.appendChild(document.createElement("a"));
var span = document.createElement("span");
// for IE
if("replaceNode" in child)
child.replaceNode(span);
// for other browsers
if("replaceWith" in child)
child.replaceWith(span);
console.log(parent.outerHTML);
You need to enable virtualization using BIOS setup.
step 1. Restart your PC and when your PC booting up then press your BIOS setup key (F1 or F2 or google it your BIOS setup key).
step 2. Go to the security menu.
step 3. Select virtualization and enable it.
Note:- BIOS setup depends on PC Manufacturer-brand.

Here's a Python 3 version of the functions from @qneill 's answer:
import base64
def encode(key, clear):
enc = []
for i in range(len(clear)):
key_c = key[i % len(key)]
enc_c = chr((ord(clear[i]) + ord(key_c)) % 256)
enc.append(enc_c)
return base64.urlsafe_b64encode("".join(enc).encode()).decode()
def decode(key, enc):
dec = []
enc = base64.urlsafe_b64decode(enc).decode()
for i in range(len(enc)):
key_c = key[i % len(key)]
dec_c = chr((256 + ord(enc[i]) - ord(key_c)) % 256)
dec.append(dec_c)
return "".join(dec)
The extra encode/decodes are needed because Python 3 has split strings/byte arrays into two different concepts, and updated their APIs to reflect that..
Recursion in Python works just as recursion in an other language, with the recursive construct defined in terms of itself:
For example a recursive class could be a binary tree (or any tree):
class tree():
def __init__(self):
'''Initialise the tree'''
self.Data = None
self.Count = 0
self.LeftSubtree = None
self.RightSubtree = None
def Insert(self, data):
'''Add an item of data to the tree'''
if self.Data == None:
self.Data = data
self.Count += 1
elif data < self.Data:
if self.LeftSubtree == None:
# tree is a recurive class definition
self.LeftSubtree = tree()
# Insert is a recursive function
self.LeftSubtree.Insert(data)
elif data == self.Data:
self.Count += 1
elif data > self.Data:
if self.RightSubtree == None:
self.RightSubtree = tree()
self.RightSubtree.Insert(data)
if __name__ == '__main__':
T = tree()
# The root node
T.Insert('b')
# Will be put into the left subtree
T.Insert('a')
# Will be put into the right subtree
T.Insert('c')
As already mentioned a recursive structure must have a termination condition. In this class, it is not so obvious because it only recurses if new elements are added, and only does it a single time extra.
Also worth noting, python by default has a limit to the depth of recursion available, to avoid absorbing all of the computer's memory. On my computer this is 1000. I don't know if this changes depending on hardware, etc. To see yours :
import sys
sys.getrecursionlimit()
and to set it :
import sys #(if you haven't already)
sys.setrecursionlimit()
edit: I can't guarentee that my binary tree is the most efficient design ever. If anyone can improve it, I'd be happy to hear how
Abstraction is about identifying commonalities and reducing features that you have to work with at different levels of your code.
e.g. I may have a Vehicle
class. A Car
would derive from a Vehicle
, as would a Motorbike
. I can ask each Vehicle
for the number of wheels, passengers etc. and that info has been abstracted and identified as common from Cars
and Motorbikes
.
In my code I can often just deal with Vehicles
via common methods go()
, stop()
etc. When I add a new Vehicle type later (e.g. Scooter
) the majority of my code would remain oblivious to this fact, and the implementation of Scooter
alone worries about Scooter
particularities.
If you have committed changes to master branch. Now you want to move that same commit to release-branch. Check the commit id(Eg:xyzabc123) for the commit.
Now try following commands
git checkout release-branch
git cherry-pick xyzabc123
git push origin release-branch
Several GUI tools like Squirrel, SQL Workbench/J, AnySQL, ExecuteQuery can export to Excel files.
Most of those tools are listed in the PostgreSQL wiki:
http://wiki.postgresql.org/wiki/Community_Guide_to_PostgreSQL_GUI_Tools
You can also use google-collections (guava) Joiner class if you want to customize the print format
To do it for your whole collection you can also use a loop (based on Niels example):
db.status.find().forEach(function(doc){
doc._id=doc.UserId; db.status_new.insert(doc);
});
db.status_new.renameCollection("status", true);
In this case UserId was the new ID I wanted to use
Mota's answer is great unless your BufferedImage came from a Monochrome Bitmap. A Monochrome Bitmap has only 2 possible values for its pixels (for example 0 = black and 1 = white). When a Monochrome Bitmap is used then the
final byte[] pixels = ((DataBufferByte) image.getRaster().getDataBuffer()).getData();
call returns the raw Pixel Array data in such a fashion that each byte contains more than one pixel.
So when you use a Monochrome Bitmap image to create your BufferedImage object then this is the algorithm you want to use:
/**
* This returns a true bitmap where each element in the grid is either a 0
* or a 1. A 1 means the pixel is white and a 0 means the pixel is black.
*
* If the incoming image doesn't have any pixels in it then this method
* returns null;
*
* @param image
* @return
*/
public static int[][] convertToArray(BufferedImage image)
{
if (image == null || image.getWidth() == 0 || image.getHeight() == 0)
return null;
// This returns bytes of data starting from the top left of the bitmap
// image and goes down.
// Top to bottom. Left to right.
final byte[] pixels = ((DataBufferByte) image.getRaster()
.getDataBuffer()).getData();
final int width = image.getWidth();
final int height = image.getHeight();
int[][] result = new int[height][width];
boolean done = false;
boolean alreadyWentToNextByte = false;
int byteIndex = 0;
int row = 0;
int col = 0;
int numBits = 0;
byte currentByte = pixels[byteIndex];
while (!done)
{
alreadyWentToNextByte = false;
result[row][col] = (currentByte & 0x80) >> 7;
currentByte = (byte) (((int) currentByte) << 1);
numBits++;
if ((row == height - 1) && (col == width - 1))
{
done = true;
}
else
{
col++;
if (numBits == 8)
{
currentByte = pixels[++byteIndex];
numBits = 0;
alreadyWentToNextByte = true;
}
if (col == width)
{
row++;
col = 0;
if (!alreadyWentToNextByte)
{
currentByte = pixels[++byteIndex];
numBits = 0;
}
}
}
}
return result;
}
The problem is that when you add a parameter to DOMDocument::saveHTML()
function, you lose the encoding. In a few cases, you'll need to avoid the use of the parameter and use old string function to find what your are looking for.
I think the previous answer works for you, but since this workaround didn't work for me, I'm adding that answer to help people who may be in my case.
Have you tried using an absolute path:
File file = new File(System.getProperty("user.dir") + "/file.txt");
The passwords cannot be decrypted as will makes a vulnerability for users. So, you can simply use password_verify()
method to compare the passwords.
if(password_verify($upass, $userRow['user_pass'])){
//code for redirecting to login screen }
where, $upass
is password entered by user and $userRow['user_pass']
is user_pass field in database which is encrypted by password_hash()
function.
even with the environment variables set, I found that ant -version
does not work in scripts. Try call ant -version
VSCode will never refresh the file if you have changes in that file that are not saved to disk. However, if the file is open and does not have changes, it will replace with the changes on disk, that is true.
There is currently no way to disable this behaviour.
well you can do this:
$(function(){
var $header = $('#header');
var $footer = $('#footer');
var $content = $('#content');
var $window = $(window).on('resize', function(){
var height = $(this).height() - $header.height() + $footer.height();
$content.height(height);
}).trigger('resize'); //on page load
});

Ruby 2.4 has Regexp#match?
: (with a ?
)
def integer?(str)
/\A[+-]?\d+\z/.match? str
end
For older Ruby versions, there's Regexp#===
. And although direct use of the case equality operator should generally be avoided, it looks very clean here:
def integer?(str)
/\A[+-]?\d+\z/ === str
end
integer? "123" # true
integer? "-123" # true
integer? "+123" # true
integer? "a123" # false
integer? "123b" # false
integer? "1\n2" # false
require 'json'
out=JSON.parse(input)
This will return a Hash
So many answers that suggest globbing as many times as number of extensions, I'd prefer globbing just once instead:
from pathlib import Path
files = {p.resolve() for p in Path(path).glob("**/*") if p.suffix in [".c", ".cc", ".cpp", ".hxx", ".h"]}
After changing the configuration files don't forget to Restart All Services

I wasted three hours of my time on it.
I know it's not the answer to the original question, but you may find yourself here with this problem.
If you want all of the duplicate items in your results, the following works.
var duplicates = list
.GroupBy( x => x ) // group matching items
.Where( g => g.Skip(1).Any() ) // where the group contains more than one item
.SelectMany( g => g ); // re-expand the groups with more than one item
In my situation I need all duplicates so that I can mark them in the UI as being errors.
You just can put your query as a subquery:
SELECT avg(count)
FROM
(
SELECT COUNT (*) AS Count
FROM Table T
WHERE T.Update_time =
(SELECT MAX (B.Update_time )
FROM Table B
WHERE (B.Id = T.Id))
GROUP BY T.Grouping
) as counts
Edit: I think this should be the same:
SELECT count(*) / count(distinct T.Grouping)
FROM Table T
WHERE T.Update_time =
(SELECT MAX (B.Update_time)
FROM Table B
WHERE (B.Id = T.Id))
I had this problem with a Silverlight 5 upgraded from a previous version.
Even re-adding the service reference still gave me an empty Reference.cs
I ended up having to create a brand new project and re-creating the service reference. This is something to try if you've spent more than about half an hour on this. Even if you're determined to fix the original project you may want to try this just to see what happens and then work backwards to try to fix the problem.
I never did figure out exactly what the problem was - but possibly something in the .csproj file wasn't upgraded or some setting went wrong.
Yes; the Objective-C method syntax is like this for a couple of reasons; one of these is so that it is clear what the parameters you are specifying are. For example, if you are adding an object to an NSMutableArray
at a certain index, you would do it using the method:
- (void)insertObject:(id)anObject atIndex:(NSUInteger)index;
This method is called insertObject:atIndex:
and it is clear that an object is being inserted at a specified index.
In practice, adding a string "Hello, World!" at index 5 of an NSMutableArray
called array
would be called as follows:
NSString *obj = @"Hello, World!";
int index = 5;
[array insertObject:obj atIndex:index];
This also reduces ambiguity between the order of the method parameters, ensuring that you pass the object parameter first, then the index parameter. This becomes more useful when using functions that take a large number of arguments, and reduces error in passing the arguments.
Furthermore, the method naming convention is such because Objective-C doesn't support overloading; however, if you want to write a method that does the same job, but takes different data-types, this can be accomplished; take, for instance, the NSNumber
class; this has several object creation methods, including:
+ (id)numberWithBool:(BOOL)value;
+ (id)numberWithFloat:(float)value;
+ (id)numberWithDouble:(double)value;
In a language such as C++, you would simply overload the number method to allow different data types to be passed as the argument; however, in Objective-C, this syntax allows several different variants of the same function to be implemented, by changing the name of the method for each variant of the function.
Some old gradle tools cannot copy .so files into build folder by somehow, manually copying these files into build folder as below can solve the problem:

Any comments on this?
You basically have two options, either define it as a service, or place it on your root scope. I would suggest that you make a service out of it to avoid polluting the root scope. You create a service and make it available in your controller like this:
<!doctype html>
<html ng-app="myApp">
<head>
<script src="http://code.jquery.com/jquery-1.9.1.min.js"></script>
<script src="http://code.angularjs.org/1.1.2/angular.min.js"></script>
<script type="text/javascript">
var myApp = angular.module('myApp', []);
myApp.factory('myService', function() {
return {
foo: function() {
alert("I'm foo!");
}
};
});
myApp.controller('MainCtrl', ['$scope', 'myService', function($scope, myService) {
$scope.callFoo = function() {
myService.foo();
}
}]);
</script>
</head>
<body ng-controller="MainCtrl">
<button ng-click="callFoo()">Call foo</button>
</body>
</html>
If that's not an option for you, you can add it to the root scope like this:
<!doctype html>
<html ng-app="myApp">
<head>
<script src="http://code.jquery.com/jquery-1.9.1.min.js"></script>
<script src="http://code.angularjs.org/1.1.2/angular.min.js"></script>
<script type="text/javascript">
var myApp = angular.module('myApp', []);
myApp.run(function($rootScope) {
$rootScope.globalFoo = function() {
alert("I'm global foo!");
};
});
myApp.controller('MainCtrl', ['$scope', function($scope){
}]);
</script>
</head>
<body ng-controller="MainCtrl">
<button ng-click="globalFoo()">Call global foo</button>
</body>
</html>
That way, all of your templates can call globalFoo()
without having to pass it to the template from the controller.
There are some good answers here, but I do want to offer one more.
Create your own static method to create and initialize a Map

class in a package that I use across projects with various utilities that I use regularly that are easy for me to write and avoids the need for a dependency on some larger library.
Here's my newMap
method:
public class CollectionUtils {
public static Map newMap(Object... keyValuePairs) {
Map map = new HashMap();
if ( keyValuePairs.length % 2 == 1 ) throw new IllegalArgumentException("Must have even number of arguments");
for ( int i=0; i<keyValuePairs.length; i+=2 ) {
map.put(keyValuePairs[i], keyValuePairs[i + 1]);
}
return map;
}
}
Usage:
import static CollectionUtils.newMap;
// ...
Map aMap = newMap("key1", 1.23, "key2", 2.34);
Map bMap = newMap(objKey1, objVal1, objKey2, objVal2, objKey3, objVal3);
// etc...
It doesn't make use of generics, but you can typecast the map as you wish (just be sure you typecast it correctly!)
Map<String,Double> aMap = (Map<String,Double>)newMap("key1", 1.23, "key2", 2.34);
Just be sure that you have include python to windows PATH variable, then run python -m ensurepip
You need to checkout the branch:
git checkout master
See the Git cheat sheets for more information.
Edit: Please note that git does not manage empty directories, so you'll have to manage them yourself. If your directory is empty, just remove it directly.
New Data-Time API is introduced with the dawn of Java 8. This is due to following issues that were caused in the old data-time API.
Difficult to handle time zone : need to write lot of code to deal with time zones.
Not Thread Safe : java.util.Date is not thread safe.
So have a look around with Java 8
import java.time.LocalDate;
import java.time.LocalTime;
import java.time.LocalDateTime;
import java.time.Month;
public class DataTimeChecker {
public static void main(String args[]) {
DataTimeChecker dateTimeChecker = new DataTimeChecker();
dateTimeChecker.DateTime();
}
public void DateTime() {
// Get the current date and time
LocalDateTime currentTime = LocalDateTime.now();
System.out.println("Current DateTime: " + currentTime);
LocalDate date1 = currentTime.toLocalDate();
System.out.println("Date : " + date1);
Month month = currentTime.getMonth();
int day = currentTime.getDayOfMonth();
int seconds = currentTime.getSecond();
System.out.println("Month : " + month);
System.out.println("Day : " + day);
System.out.println("Seconds : " + seconds);
LocalDateTime date2 = currentTime.withDayOfMonth(17).withYear(2018);
System.out.println("Date : " + date2);
//Prints 17 May 2018
LocalDate date3 = LocalDate.of(2018, Month.MAY, 17);
System.out.println("Date : " + date3);
//Prints 04 hour 45 minutes
LocalTime date4 = LocalTime.of(4, 45);
System.out.println("Date : " + date4);
// Convert to a String
LocalTime date5 = LocalTime.parse("20:15:30");
System.out.println("Date : " + date5);
}
}
Output of the coding above :
Current DateTime: 2018-05-17T04:40:34.603
Date : 2018-05-17
Month : MAY
Day : 17
Seconds : 34
Date : 2018-05-17T04:40:34.603
Date : 2018-05-17
Date : 04:45
Date : 20:15:30
$1, $2, etc will contain the value of captures from the last successful match - it's important to check whether the match succeeded before accessing them, i.e.
if ( $var =~ m/( )/ ) { # use $1 etc... }
An example of the problem - $1 contains 'Quick' in both print statements below:
#!/usr/bin/perl
'Quick brown fox' =~ m{ ( quick ) }ix;
print "Found: $1\n";
'Lazy dog' =~ m{ ( quick ) }ix;
print "Found: $1\n";
Verbose, but copied from the HTTP 1.1 method specification at http://www.w3.org/Protocols/rfc2616/rfc2616-sec9.html
The GET method means retrieve whatever information (in the form of an entity) is identified by the Request-URI. If the Request-URI refers to a data-producing process, it is the produced data which shall be returned as the entity in the response and not the source text of the process, unless that text happens to be the output of the process.
The semantics of the GET method change to a "conditional GET" if the request message includes an If-Modified-Since, If-Unmodified-Since, If-Match, If-None-Match, or If-Range header field. A conditional GET method requests that the entity be transferred only under the circumstances described by the conditional header field(s). The conditional GET method is intended to reduce unnecessary network usage by allowing cached entities to be refreshed without requiring multiple requests or transferring data already held by the client.
The semantics of the GET method change to a "partial GET" if the request message includes a Range header field. A partial GET requests that only part of the entity be transferred, as described in section 14.35. The partial GET method is intended to reduce unnecessary network usage by allowing partially-retrieved entities to be completed without transferring data already held by the client.
The response to a GET request is cacheable if and only if it meets the requirements for HTTP caching described in section 13.
See section 15.1.3 for security considerations when used for forms.
The POST method is used to request that the origin server accept the entity enclosed in the request as a new subordinate of the resource identified by the Request-URI in the Request-Line. POST is designed to allow a uniform method to cover the following functions:
- Annotation of existing resources;
- Posting a message to a bulletin board, newsgroup, mailing list,
or similar group of articles;
- Providing a block of data, such as the result of submitting a
form, to a data-handling process;
- Extending a database through an append operation.
The actual function performed by the POST method is determined by the server and is usually dependent on the Request-URI. The posted entity is subordinate to that URI in the same way that a file is subordinate to a directory containing it, a news article is subordinate to a newsgroup to which it is posted, or a record is subordinate to a database.
The action performed by the POST method might not result in a resource that can be identified by a URI. In this case, either 200 (OK) or 204 (No Content) is the appropriate response status, depending on whether or not the response includes an entity that describes the result.
If a resource has been created on the origin server, the response SHOULD be 201 (Created) and contain an entity which describes the status of the request and refers to the new resource, and a Location header (see section 14.30).
Responses to this method are not cacheable, unless the response includes appropriate Cache-Control or Expires header fields. However, the 303 (See Other) response can be used to direct the user agent to retrieve a cacheable resource.
POST requests MUST obey the message transmission requirements set out in section 8.2.
See section 15.1.3 for security considerations.
The PUT method requests that the enclosed entity be stored under the supplied Request-URI. If the Request-URI refers to an already existing resource, the enclosed entity SHOULD be considered as a modified version of the one residing on the origin server. If the Request-URI does not point to an existing resource, and that URI is capable of being defined as a new resource by the requesting user agent, the origin server can create the resource with that URI. If a new resource is created, the origin server MUST inform the user agent via the 201 (Created) response. If an existing resource is modified, either the 200 (OK) or 204 (No Content) response codes SHOULD be sent to indicate successful completion of the request. If the resource could not be created or modified with the Request-URI, an appropriate error response SHOULD be given that reflects the nature of the problem. The recipient of the entity MUST NOT ignore any Content-* (e.g. Content-Range) headers that it does not understand or implement and MUST return a 501 (Not Implemented) response in such cases.
If the request passes through a cache and the Request-URI identifies one or more currently cached entities, those entries SHOULD be treated as stale. Responses to this method are not cacheable.
The fundamental difference between the POST and PUT requests is reflected in the different meaning of the Request-URI. The URI in a POST request identifies the resource that will handle the enclosed entity. That resource might be a data-accepting process, a gateway to some other protocol, or a separate entity that accepts annotations. In contrast, the URI in a PUT request identifies the entity enclosed with the request -- the user agent knows what URI is intended and the server MUST NOT attempt to apply the request to some other resource. If the server desires that the request be applied to a different URI,
it MUST send a 301 (Moved Permanently) response; the user agent MAY then make its own decision regarding whether or not to redirect the request.
A single resource MAY be identified by many different URIs. For example, an article might have a URI for identifying "the current version" which is separate from the URI identifying each particular version. In this case, a PUT request on a general URI might result in several other URIs being defined by the origin server.
HTTP/1.1 does not define how a PUT method affects the state of an origin server.
PUT requests MUST obey the message transmission requirements set out in section 8.2.
Unless otherwise specified for a particular entity-header, the entity-headers in the PUT request SHOULD be applied to the resource created or modified by the PUT.
The DELETE method requests that the origin server delete the resource identified by the Request-URI. This method MAY be overridden by human intervention (or other means) on the origin server. The client cannot be guaranteed that the operation has been carried out, even if the status code returned from the origin server indicates that the action has been completed successfully. However, the server SHOULD NOT indicate success unless, at the time the response is given, it intends to delete the resource or move it to an inaccessible location.
A successful response SHOULD be 200 (OK) if the response includes an entity describing the status, 202 (Accepted) if the action has not yet been enacted, or 204 (No Content) if the action has been enacted but the response does not include an entity.
If the request passes through a cache and the Request-URI identifies one or more currently cached entities, those entries SHOULD be treated as stale. Responses to this method are not cacheable.

Whenever you change the email field, the link is updated automatically. This requires a small amount of jQuery. So now your form will work as needed, but your link will be updated dynamically so that when someone clicks on it, it contains what they entered in the email field. You should validate the input on the receiving page.
$('input[name="email"]').change(function(){
$('#regLink').attr('href')+$('input[name="email"]').val();
});
There are already many great answers, but when I want to change date for multiple commits in one day or in one month, I don't find a proper answer. So I create a new script for this with explaintion, hope it will help someone:
#!/bin/bash
# change GIT_AUTHOR_DATE for commit at Thu Sep 14 13:39:41 2017 +0800
# you can change the data_match to change all commits at any date, one day or one month
# you can also do the same for GIT_COMMITTER_DATE
git filter-branch --force --env-filter '
date_match="^Thu, 14 Sep 2017 13+"
# GIT_AUTHOR_DATE will be @1505367581 +0800, Git internal format
author_data=$GIT_AUTHOR_DATE;
author_data=${author_data#@}
author_data=${author_data% +0800} # author_data is 1505367581
oneday=$((24*60*60))
# author_data_str will be "Thu, 14 Sep 2017 13:39:41 +0800", RFC2822 format
author_data_str=`date -R -d @$author_data`
if [[ $author_data_str =~ $date_match ]];
then
# remove one day from author_data
new_data_sec=$(($author_data-$oneday))
# change to git internal format based on new_data_sec
new_data="@$new_data_sec +0800"
export GIT_AUTHOR_DATE="$new_data"
fi
' --tag-name-filter cat -- --branches --tags
The date will be changed:
AuthorDate: Wed Sep 13 13:39:41 2017 +0800
It looks like XMLHttpRequest
has been replaced by the Fetch API. Google published a good introduction that includes this example doing what you want:
fetch('./api/some.json')
.then(
function(response) {
if (response.status !== 200) {
console.log('Looks like there was a problem. Status Code: ' +
response.status);
return;
}
// Examine the text in the response
response.json().then(function(data) {
console.log(data);
});
}
)
.catch(function(err) {
console.log('Fetch Error :-S', err);
});
However, you probably want to call response.text()
instead of response.json()
.
benefit.indexOf(map4)
It either returns an index or -1 if the items is not found.
I strongly recommend wrapping the map in some object and use generics if possible.
I modified the answer from rayzinnz to end the script with a specific key, in this case the escape key
import threading as th
import time
import keyboard
keep_going = True
def key_capture_thread():
global keep_going
a = keyboard.read_key()
if a== "esc":
keep_going = False
def do_stuff():
th.Thread(target=key_capture_thread, args=(), name='key_capture_thread', daemon=True).start()
i=0
while keep_going:
print('still going...')
time.sleep(1)
i=i+1
print (i)
print ("Schleife beendet")
do_stuff()
To count total words Or to count total words without repeat word count
public static void main(String[] args) {
// TODO Auto-generated method stub
String test = "I am trying to make make make";
Pattern p = Pattern.compile("\\w+");
Matcher m = p.matcher(test);
HashSet<String> hs = new HashSet<>();
int i=0;
while (m.find()) {
i++;
hs.add(m.group());
}
System.out.println("Total words Count==" + i);
System.out.println("Count without Repetation ==" + hs.size());
}
}
Output :
Total words Count==7
Count without Repeatation ==5
I wrote a clean functional method of playing sounds:
sounds = {
test : new Audio('/assets/sounds/test.mp3')
};
sound_volume = 0.1;
function playSound(sound) {
sounds[sound].volume = sound_volume;
sounds[sound].play();
}
function stopSound(sound) {
sounds[sound].pause();
}
function setVolume(sound, volume) {
sounds[sound].volume = volume;
sound_volume = volume;
}
In Bash and zsh you can do this with Brace Expansion. This simply expands a list of items in braces. For example:
# echo {vanilla,chocolate,strawberry}-ice-cream
vanilla-ice-cream chocolate-ice-cream strawberry-ice-cream
So you can do your rename as follows:
mv {,new.}original.filename
as this expands to:
mv original.filename new.original.filename
If that helps in some cases, it is possible to use the unicode character:
NSLog(@"Test percentage \uFF05");
Couldn't this simply be done by getting actual position of the mouse pointer then calculating and compensating sprite/scene mouse actions based off this compensation?
For instance you need the mouse pointer to be bottom center, but it sits top left; hide the cursor, use a shifted cursor image. Shift the cursor movement and map mouse input to match re-positioned cursor sprite (or 'control') clicks When/if bounds are hit, recalculate. If/when the cursor actually hits the point you want it to be, remove compensation.

The DUAL table is a special one-row table present by default in all Oracle database installations. It is suitable for use in selecting a pseudocolumn such as SYSDATE or USER
The table has a single VARCHAR2(1) column called DUMMY that has a value of "X"
You can read all about it in http://en.wikipedia.org/wiki/DUAL_table
This is fairly easy on processing power required:
(string1(.|\n)*string2)|(string2(.|\n)*string1)
I used this in visual studio 2013 to find all files that had both string 1 and 2 in it.
In most of the cases, deleting all the node packages and then installing them again, solve the problem.
But In my case node_modules folder has not write permission.
Android Studio debug.keystore file path depend on environment variable ANDROID_SDK_HOME.
If ANDROID_SDK_HOME defined, then file placed in SDK's subfolder named .android .
When not defined, then keystore placed at user home path in same subfolder:
- %HOMEPATH%\.android\ on Windows
- $HOME/.android/ on Linux
WARNING: Using
Access-Control-Allow-Origin: *
can make your API/website vulnerable to cross-site request forgery (CSRF) attacks. Make certain you understand the risks before using this code.
It's very simple to solve if you are using PHP. Just add the following script in the beginning of your PHP page which handles the request:
<?php header('Access-Control-Allow-Origin: *'); ?>
If you are using Node-red you have to allow CORS in the node-red/settings.js
file by un-commenting the following lines:
// The following property can be used to configure cross-origin resource sharing
// in the HTTP nodes.
// See https://github.com/troygoode/node-cors#configuration-options for
// details on its contents. The following is a basic permissive set of options:
httpNodeCors: {
origin: "*",
methods: "GET,PUT,POST,DELETE"
},
If you are using Flask same as the question; you have first to install flask-cors
$ pip install -U flask-cors
Then include the Flask cors in your application.
from flask_cors import CORS
A simple application will look like:
from flask import Flask
from flask_cors import CORS
app = Flask(__name__)
CORS(app)
@app.route("/")
def helloWorld():
return "Hello, cross-origin-world!"
For more details, you can check the Flask documentation.
multipart/form-data
Note. Please consult RFC2388 for additional information about file uploads, including backwards compatibility issues, the relationship between "multipart/form-data" and other content types, performance issues, etc.
Please consult the appendix for information about security issues for forms.
The content type "application/x-www-form-urlencoded" is inefficient for sending large quantities of binary data or text containing non-ASCII characters. The content type "multipart/form-data" should be used for submitting forms that contain files, non-ASCII data, and binary data.
The content type "multipart/form-data" follows the rules of all multipart MIME data streams as outlined in RFC2045. The definition of "multipart/form-data" is available at the [IANA] registry.
A "multipart/form-data" message contains a series of parts, each representing a successful control. The parts are sent to the processing agent in the same order the corresponding controls appear in the document stream. Part boundaries should not occur in any of the data; how this is done lies outside the scope of this specification.
As with all multipart MIME types, each part has an optional "Content-Type" header that defaults to "text/plain". User agents should supply the "Content-Type" header, accompanied by a "charset" parameter.
application/x-www-form-urlencoded
This is the default content type. Forms submitted with this content type must be encoded as follows:
Control names and values are escaped. Space characters are replaced by +', and then reserved characters are escaped as described in [RFC1738], section 2.2: Non-alphanumeric characters are replaced by
%HH', a percent sign and two hexadecimal digits representing the ASCII code of the character. Line breaks are represented as "CR LF" pairs (i.e., %0D%0A').
The control names/values are listed in the order they appear in the document. The name is separated from the value by
=' and name/value pairs are separated from each other by `&'.
application/x-www-form-urlencoded
the body of the HTTP message sent to the server is essentially one giant query string -- name/value pairs are separated by the ampersand (&), and names are separated from values by the equals symbol (=). An example of this would be:
MyVariableOne=ValueOne&MyVariableTwo=ValueTwo
The content type "application/x-www-form-urlencoded" is inefficient for sending large quantities of binary data or text containing non-ASCII characters. The content type "multipart/form-data" should be used for submitting forms that contain files, non-ASCII data, and binary data.
Even though your JDK in eclipse is 1.7, you need to make sure eclipse compilance level also set to 1.7. You can check compilance level--> Window-->Preferences--> Java--Compiler--compilance level.
Unsupported major minor error happens in cases where compilance level doesn't match with runtime.
std::string s(v.begin(), v.end());
Where v is pretty much anything iterable. (Specifically begin() and end() must return InputIterators.)
To be able to access the form in your controller, you have to add it to a dummy scope object.
Something like $scope.dummy = {}
For your situation this would mean something like:
<form name="dummy.customerForm">
In your controller you will be able to access the form by:
$scope.dummy.customerForm
and you will be able to do stuff like
$scope.dummy.customerForm.$setPristine()
Having a '.' in your models will ensure that prototypal inheritance is in play. So, use
<input type="text" ng-model="someObj.prop1">
rather than<input type="text" ng-model="prop1">
If you really want/need to use a primitive, there are two workarounds:
1.Use $parent.parentScopeProperty in the child scope. This will prevent the child scope from creating its own property. 2.Define a function on the parent scope, and call it from the child, passing the primitive value up to the parent (not always possible)
As a follow on, you could select "all nodes with a particular attribute" like this:
//*[@id='4']
They are the same thing. .hide()
calls a jQuery function and allows you to add a callback function to it. So, with .hide()
you can add an animation for instance.
.css("display","none")
changes the attribute of the element to display:none
. It is the same as if you do the following in JavaScript:
document.getElementById('elementId').style.display = 'none';
The .hide()
function obviously takes more time to run as it checks for callback functions, speed, etc...
If that helps anyone, (even if this is kind of poor as we must only allow this for dev purpose) here is a Java solution as I encountered the same issue.
[Edit] Do not use the wild card * as it is a bad solution, use localhost
if you really need to have something working locally.
public class SimpleCORSFilter implements Filter {
public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException {
HttpServletResponse response = (HttpServletResponse) res;
response.setHeader("Access-Control-Allow-Origin", "my-authorized-proxy-or-domain");
response.setHeader("Access-Control-Allow-Methods", "POST, GET");
response.setHeader("Access-Control-Max-Age", "3600");
response.setHeader("Access-Control-Allow-Headers", "Content-Type, Access-Control-Allow-Headers, Authorization, X-Requested-With");
chain.doFilter(req, res);
}
public void init(FilterConfig filterConfig) {}
public void destroy() {}
}
You can use equals()
.
enum.equals(String)
Cut file via operating system context menu as you usually do, then instead of doing regular paste, right click to bring context menu, then choose TortoiseSVN -> Paste
(make sure you commit from root to include both old and new files in the commit).
For category relations insertion I came across the same problem and had no idea, except that in my eloquent model I used Self() to have an instance of the same class in foreach to record multiple saves and grabing ids.
foreach($arCategories as $v)
{
if($v>0){
$obj = new Self(); // this is to have new instance of own
$obj->page_id = $page_id;
$obj->category_id = $v;
$obj->save();
}
}
without "$obj = new Self()" it only saves single record (when $obj was $this)
Yes you can infact php is one of the few languages who provide such support..
foreach($arr as $key=>$value)
{
}
As mentioned by h4z3, For a practical use, Sometimes your data is too big to directly load everything, or you have a generator, or real-time incoming data, you could use w+ to store in a file and read later.
